Building 11Ligocka St. 103, 40-568 Katowice, PolandT: +48 (0) 32 438 4778E:**************************IR15 Dual Gas Series DatasheetInfrared Dual Gas Sensor for Hazardous Environments(Portable and Fixed Systems)The SGX infrared sensors use the proven Non-Dispersive Infrared (NDIR) principle to detect and monitor the presence of gases. With an infrared source and specific filtering on the pyroelectric detectors mounted inside the optical/gas cavity, individual gases or types of gas can be identified and their concentrations determined.These sensors are suitable for reliable monitoring of gas levels in general safety applications where the sensor size is restricted and require a flameproof enclosure for hazardous environments.The IR15 Series contain two active detector elements for simultaneous monitoring of Carbon Dioxide and Methane or Hydrocarbon mixtures in the same size housing as some of the single gas sensors from the IR1xxx series sensors, making the sensor more cost effective than two separate sensors.APPLICATIONS∙ Oil & Gas∙ Petrochemical ∙ Biogas∙Wastewater ∙ Utilities ∙ Steelworks∙ Confined Space Entry ∙ Indoor Air QualityFEATURES∙ For detection of the following gases:o Carbon Dioxide & Hydrocarbons, o Hydrocarbons Mixtures ∙Gas concentration ranges:o 0 - 5% Carbon Dioxide(also suitable for 0 to 0.5%v/v) o 0 - 100% Carbon Dioxide(also suitable for 0 to 10%) o 0 - 100%v/v Hydrocarbons(also suitable for 0 to 100%LEL)∙ 19mm sensor height∙ Embedded thermistor for improved temperature compensation∙ Diffused gas sampling via mesh ∙ Low power∙ Reference channel for self-compensation∙ Special gold plated optical gas cavity for stable signal levels∙ Operational in varying temperature, pressure and humidity∙ Fast response∙ Rugged stainless steel construction ∙ No moving parts∙ Immunity from ‘poisoning’∙Reliable fail-safe operation∙Certified: ATEX, IECEx, CSA and ULOPERATIONTo operate, the sensors must be interfaced to a suitable circuit for power supply, output amplification and signal processing. Sensor outputs require linearisation and compensation for ambient temperature variation using algorithms in the system firmware. This is necessary for sensors to meet their full performance specification. An embedded temperature sensor facilitates this compensation on certain types. Further compensation for pressure changes can also be made in an algorithm, provided there is a suitable input from a pressure sensor.A set of Application Notes is available from the SGX Sensortech Ltd website, to explain more about NDIR gas sensing and provide advice for the end-user on interfacing the sensors and processing signals.TECHNICAL SPECIFICATIONCONFIGURATIONSThe Highest Concentration Range is the highest range the sensor is suitable. The Lowest Concentration Range is the lowest range the sensor is suitable. The use of the sensor beyond these ranges will affect the sensor’s performance.IR15TTThe IR15TT can be used in all applications for general monitoring of both relatively low concentrations of carbon dioxide and simultaneous %LEL and %v/v concentrations of Group II hydrocarbons, including benzene. The sensors contain a broadband hydrocarbon detector which are cross sensitive to most hydrocarbons and can therefore be calibrated to a specific target gas or a number of gases that can then be selected in the configuration of the customer’s gas measurement instrument.IR15TT-MThe IR15TT-M is very similar to the IR15TT except that a narrowband hydrocarbon detector is used. The sensor can still be used to monitor the same levels of carbon dioxide and hydrocarbons but are unsuitable for the detection of benzene. The narrowband detector also has a slightly lower response to humidity than the IR15TT, but is generally more cross-sensitive to other hydrocarbons.IR15TT-RThe IR15TT-R was designed specifically for Biogas applications for the simultaneous detection of carbon dioxide up to 100%v/v and %LEL and %v/v concentrations of hydrocarbons, but can be potentially used for other applications. The IR15TT-R contains the narrowband detector which is unsuitable for the detection of benzene.IR15TT-DThe IR15TT-D is fitted with both the narrowband and broadband hydrocarbon detectors with differing centre wavelength and bandwidth to potentially differentiate between hydrocarbons. The sensor was designed for the gas instruments being used by utilities companies to help differentiate between different compositions of natural gas.HANDLING PRECAUTIONS1. Do not allow sensors to fall on the floor. This could cause IR Source filament breakage, damage to the pins and the gasentrance aperture.2. Do not apply mechanical force against the gas entrance aperture.3. Do not immerse sensors in water or other fluids.4. Protect the gas entrance aperture against dust ingress and sprayed materials.5. Anti-static handling precautions must be taken.PERFORMANCEFor test purposes, all data taken using the following conditions:- Performance as tested in the SGX IR-EK2 Evaluation Kit directly after calibration.- SGX linearisation and temperature compensation algorithms applied; see Infrared Sensor Application Notes.- IR Source Voltage 5V, square wave, at 4 Hz and 50% duty cycle. Running the IR Source at 3V will decrease performance due to lower output signals.- Ambient temperature (20°C) and pressure (101 kPa).- All gases diluted in dry nitrogen.- Performance for the Hydrocarbons refers to Methane only. Most other hydrocarbons will have an improved performance.- Performance data is the same for the supported IR Source variants (“_1” variants).- Refer to Application Notes for more information.(2) Production Test Limits, using standard test gases of Dry Nitrogen, 2%v/v Carbon Dioxide and 5%v/v Methane, where appropriate . (3) A 0.30 absorbance is equivalent to a 30% decrease in the Active peak-to-peak output.(4)The minimum detection level is the smallest detectable change in concentration based upon a 2 sigma variantion. The best detectable change occurs at 0% gas concentration due to the non-linear output of the detector (see Fractional Absorbance Curves).(5) Performance for most hydrocarbons will be better than for methane for equiavlent concentrations, as methane is one of the lower sensitive gasescompared to other hydocarbons.(6) After linearisation using the recommended method of linearisation and based upon a calibration gas with a concentration >75% of the full-scale. (7) Using average Alpha and Beta coefficients based upon test data from the instrument in which the sensor is being tested. Refer to ApplicationNotes for information on calculating Alpha and Beta coefficients. Accuracy can be improved by measuring each sensor over temperature to define specific Alpha or Alpha & Beta coefficients.(8) After sensor stabilisation and over a period of 8 hours. (9) Difference in response when changed from 0 %RH to 90 %RH.(10) Sensors can be used over a greater ambient pressure using pressure compensation of the concentration. An external pressure sensor will berequred for this.FRACTIONAL ABSORBANCE CURVESThese show the typical sensitivity versus concentration before linearisation for the range of gases. For further explanation, refer to the Infrared Sensor Application Notes.Primary Target GasesNote: Both IR15TT-D channels have a similar response to methane but different responses to other alkanes (see table below).Relative Absorbance of Narrowband and Broadband Detectors to AlkanesMethane 5%v/v Ethane (0.5%v/v) Propane (0.35%v/v) Narrowband1.00 0.82IR15TT-D / IR15TT-MBroadband 1.00CERTIFICATIONSCSAULATEXIECEXINSTRUCTIONS SPECIFIC TO HAZARDOUS AREA INSTALLATIONS(Ref: EU ATEX Directive 2014/34/EU)1.

Long-term exposure to conditions outside normal range, especially at high humidity, may temporarily affect the sensor performance. Prolonged exposure to extreme conditions may accelerate aging. To ensure stable operation of the gas sensor, the conditions described in the document SGP Handling and Assembly Instructionsregarding exposure to exceptionally high concentrations of some organic or inorganic compounds have to be met, particularly during operation. Please also refer to the Design-in Guide for optimal integration of the SGP30.2Electrical SpecificationsFigure 7 Typical application circuit (for better clarity in the image, the positioning of the pins does not reflect the positions on the real sensor).The electrical specifications of the SGP30 are shown in Table 3. The power supply pins must be decoupled with a 100 nF capacitor that shall be placed as close as possible to pin VDD – see Figure 7. The required decoupling depends on the power supply network connected to the sensor. We also recommend VDD and VDDH pins to be shorted.SCL is used to synchronize the communication between the microcontroller and the sensor. The SDA pin is used to transfer data to and from the sensor. For safe communication, the timing specifications defined in the I2C manual4 must be met. Both SCL and SDA lines are open-drain I/Os with diodes to VDD and VSS. They should be connected to external pull-up resistors. To avoid signal contention, the microcontroller must only drive SDA and SCL low. The external pull-up resistors (e.g. R p = 10 kΩ) are required to pull the signal high. For dimensioning resistor sizes please take bus capacity and communication frequency into account (see for example Section 7.1 of NXPs I2C Manual for more details4). It should be noted that pull-up5.2Communication TimingsDefault conditions of 25 °C and 1.8 V supply voltage apply to values in the table below, unless otherwise stated.4Parameter Symbol Conditions Min.

Bold SDA lines are controlled by the sensor; plain SDA lines are controlled by the micro-controller. Note that SDA valid read time is triggered by falling edge of preceding toggle.6 Operation and CommunicationThe SGP30 supports I 2C fast mode. For detailed information on the I 2C protocol, refer to NXP I 2C-bus specification 4. All SGP30 commands and data are mapped to a 16-bit address space. Additionally, data and commands are protected with a CRC checksum to increase the communication reliability. The 16-bit commands that are sent to the sensor already include a 3-bit CRC checksum. Data sent from and received by the sensor is always succeeded by an 8-bit CRC.In write direction it is mandatory to transmit the checksum, since the SGP30 only accepts data if it is followed by the correct checksum. In read direction it is up to the master to decide if it wants to read and process the checksum.SGP30 Hex. Code I 2C address0x58Table 8 I 2C device address.The typical communication sequence between the I 2C master (e.g., a microcontroller in a host device) and the sensor is described as follows:SCL70% 30%t LOW1/f SCL t HIGHt Rt FSDA70% 30%t SU;DATt HD;DATDATA INt RSDA70% 30% DATA OUTt VD;DATt F1.The sensor is powered up, communication is initialized2.The I2C master periodically requests measurement and reads data, in the following sequence:a.I2C master sends a measurement commandb.I2C master waits until the measurement is finished, either by waiting for the maximum execution time or bywaiting for the expected duration and then poll data until the read header is acknowledged by the sensor(expected durations are listed in Table 9)c.I2C master reads out the measurement result6.1Power-Up and Communication StartThe sensor starts powering-up after reaching the power-up threshold voltage V POR specified in Table 6. After reaching this threshold voltage, the sensor needs the time t PU to enter the idle state. Once the idle state is entered it is ready to receive commands from the master.Each transmission sequence begins with a START condition (S) and ends with a STOP condition (P) as described in the I2C-bus specification.6.2Measurement Communication SequenceA measurement communication sequence consists of a START condition, the I2C write header (7-bit I2C device address plus 0 as the write bit) and a 16-bit measurement command. The proper reception of each byte is indicated by the sensor. It pulls the SDA pin low (ACK bit) after the falling edge of the 8th SCL clock to indicate the reception. With the acknowledgement of the measurement command, the SGP30 starts measuring.When the measurement is in progress, no communication with the sensor is possible and the sensor aborts the communication with a NACK condition.After the sensor has completed the measurement, the master can read the measurement results by sending a START condition followed by an I2C read header. The sensor will acknowledge the reception of the read header and responds with data. The response data length is listed in Table 9 and is structured in data words, where one word consists of two bytes of data followed by one byte CRC checksum. Each byte must be acknowledged by the microcontroller with an ACK condition for the sensor to continue sending data. If the sensor does not receive an ACK from the master after any byte of data, it will not continue sending data.After receiving the checksum for the last word of data, an NACK and STOP condition have to be sent (see Figure 9).The I2C master can abort the read transfer with a NACK followed by a STOP condition after any data byte if it is not interested in subsequent data, e.g. the CRC byte or following data bytes, in order to save time. Note that the data cannot be read more than once, and access to data beyond the specified amount will return a pattern of 1s.6.3Measurement CommandsThe available measurement commands of the SGP30 are listed in Table 9.Feature SetThe SGP30 features a versioning system for the available set of measurement commands and on-chip algorithms. This so called feature set version number can be read out by sending a “Get_feature_set_version” command. The sensor responds with 2 data bytes (MSB first) and 1 CRC byte. This feature set version number is used to refer to a corresponding set of available measurement commands as listed in Table 9.Air Quality SignalsThe SGP30 uses a dynamic baseline correction algorithm and on-chip calibration parameters to provide two complementary air quality signals. Based on the sensor signals a total VOC signal (TVOC) and a CO2equivalent signal (CO2eq) are calculated. Sending an “Init_air_quality” command starts the air quality measurement. After the “Init_air_quality” command, a “Measure_air_quality” command has to be sent in regular intervals of 1s to ensure proper operation of the dynamic baseline correction algorithms. The sensor responds with 2 data bytes (MSB first) and 1 CRC byte for each of the two preprocessed air quality signals in the order CO2eq (ppm) and TVOC (ppb).The SGP30 also provides the possibility to read and write the baseline values of the baseline correction algorithm. This feature is used to save the baseline in regular intervals on an external non-volatile memory and restore it after a new power-up or soft reset of the sensor. The command “Get_baseline” returns the baseline values for the two air quality signals. T he sensorresponds with 2 data bytes (MSB first) and 1 CRC byte for each of the two values in the order CO 2eq and TVOC. These two values should be stored on an external memory. After a power-up or soft reset, the baseline of the baseline correction algorit hm can be restored by using the “Set_baseline” command with the two baseline values as parameters in the order as (TVOC, CO 2eq). An example implementation of a generic driver for the baseline algorithm can be found in the document SGP30_driver_integration_guide .A new “Init_air_quality” command has to be sent after every power -up or soft reset.Sensor SignalsThe command “Measure_signals” is intended for part verification and testing purposes. It returns the sensor signals which are used as inputs for the on-chip calibration and baseline correction algorithms as shown in Figure 6. The command performs a measurement to which the sensor responds with 2 data bytes (MSB first) and 1 CRC byte (see Figure 9) for 2 sensor signals in the order H2_signal (s out_H2) and Ethanol_signal (s out_EthOH ) Both signals can be used to calculate gas concentrations c relative to a reference concentration c ref byln (c c ref ⁄)=s ref −s outawith a = 512 (9-bit shift), s ref the H2_signal or Ethanol_signal output at the reference concentration, and s out = s out_H2 or s out = s out_EthOH .Measure TestThe command “Measure_test ” which is included for integration and production line testing runs an on-chip self-test. In case of a successful self-test the sensor returns the fixed data pattern 0xD400 (with correct CRC).Table 9 Measurement commands.6.4 Soft ResetA sensor reset can be generated using the “General Call” mode according to I 2C-bus specification. It is important to understand that a reset generated in this way is not device specific. All devices on the same I 2C bus that support the General Call mode will perform a reset. The appropriate command consists of two bytes and is shown in Table 10.Table 10 Reset through the General Call address (Clear blocks are controlled by the microcontroller, grey blocks by the sensor.).6.5Get Serial IDThe readout of the serial ID register can be used to identify the chip and verify the presence of the sensor. The appropriate command structure is shown in Table 11. After issuing the measurement command and sending the ACK Bit the sensor needs the time t IDLE = 0.5ms to respond to the I2C read header with an ACK Bit. Hence, it is recommended to wait t IDLE =0.5ms before issuing the read header.The get serial ID command returns 3 words, and every word is followed by an 8-bit CRC checksum. Together the 3 words constitute a unique serial ID with a length of 48 bits.The ID returned with this command are represented in the big endian (or MSB first) format.Table 11 Get serial ID command.6.6Checksum CalculationThe 8-bit CRC checksum transmitted after each data word is generated by a CRC algorithm. Its properties are displayed in Table 12. The CRC covers the contents of the two previously transmitted data bytes. To calculate the checksum only these two previously transmitted data bytes are used.Table 12 I2C CRC properties.6.7Communication Data SequencesFigure 9 Communication sequence for starting a measurement and reading measurement results.7Quality7.1Environmental StabilityThe qualification of the SGP30 will be performed based on the JEDEC JESD47 qualification test method.7.2Material ContentsThe device is fully RoHS and WEEE compliant, e.g., free of Pb, Cd, and Hg.8Device PackageSGP30 sensors are provided in a DFN (dual flat no leads) package with an outline of 2.45 × 2.45 × 0.9 mm3and a terminal pitch of 0.8 mm. The circular sensor opening of maximally 1.6 mm diameter is centered on the top side of the package. The sensor chip is assembled on a Ni/Pd/Au plated copper lead frame. Sensor chip and lead frame are over-molded by a black, epoxy-based mold compound. Please note that the side walls of the package are diced and therefore the lead frame sidewall surfaces are not plated. SGP308.1TraceabilityAll SGP30 sensors are laser marked for simple identification and traceability. The marking on the sensor consists of the product name and a 4-digit, alphanumeric tracking code. This code is used by Sensirion for batch-level tracking throughout production, calibration, and testing. Detailed tracking data can be provided upon justified request. The pin-1 location is indicated by the keyhole pattern in the light-colored central area. See Figure 10 for illustration.Figure 10 Laser marking on SGP30. The pin-1 location is indicated by the keyhole pattern in the light-colored central area. The bottom line contains a 4-digit alphanumeric tracking code8.2 Package OutlineFigure 11 Package outlines drawing of the SGP30 with nominal values. Dimensions are given in millimeters. The die pad shows a small recess in the bottom left part. * These dimensions are not well defined and given as a reference only.8.3 Landing PatternFigure 12 shows the PCB landing pattern. The landing pattern is understood to be the metal layer on the PCB, onto which the DFN pads are soldered. The solder mask is understood to be the insulating layer on top of the PCB covering the copper traces. It is recommended to design the solder mask as a Non-Solder Mask Defined (NSMD) type. For solder paste printing it is recommended to use a laser-cut, stainless steel stencil with electro-polished trapezoidal walls and with 0.125 to 0.150 mm stencil thickness. The length of the stencil apertures for the I/O pads should be the same as the PCB pads. However, the position of the stencil apertures should have an offset of 0.1 mm away from the package center, as indicated in Figure 12. The die pad aperture should cover 70 – 90 % of the die pad area, resulting in a size of about 1.05 mm x 1.5 mm.For information on the soldering process and further recommendation on the assembly process please contact Sensirion.Figure 12 Recommended landing pattern.o9 Ordering InformationSamples are available upon request.

ACD10产品说明书红外二氧化碳传感器•优异的长期稳定性•良好的选择性•无氧气依赖性•标准数字输出•响应迅速•恢复时间快•抗干扰能力强产品综述ACD10利用非分散红外（NDIR）原理对空气中的二氧化碳浓度进行检测。
ACD10具有良好的选择性、无氧气依赖性、寿命长等优点；具备数字接口输出，方便使用。
ACD10是一款集成红外吸收气体检测技术、精密光路和高精度信号检测电路的高性能传感器。
应用范围ACD10的应用场景广泛，适用于空气质量监控设备、新风系统、空气净化设备、暖通制冷设备等。
图1.ACD10实物图1.工作原理ACD10传感器是基于CO2气体的光谱吸收原理设计而成的。
如图2所示，传感器有光源、气室和红外传感器三个部分组成。
红外传感器是用于测量光源发射的红外线强度，当CO2通过气体进气口流入气室，从出气口流出气室，CO2会吸收气室内特定波长的红外光，且CO2的浓度变化会对红外吸收量有影响。
当CO2的浓度发生变化时，红外线传感器接收到的光源信号强度也会发生变化。
传感器通过检测特定波长的红外光的吸收率，计算得出CO2浓度。
