MQ137 Test CircuitInstructions: The above fig is the basic test circuit of MQ137.The sensorrequirestwo voltageinputs: heater voltage(V H ) and circuit voltage(V C ). V H is used to supply standard working temperature to the sensor and it can adopts DC or AC power, while V RL is the voltage of load resistance R L which is in series with sensor. Vc supplies the detect voltage to load resistance R Land it should adopts DC power.Description of Sensor CharactersNH3 AirCautions1 .Following conditions must be prohibited1.1 Exposed to organic silicon steamSensing material will lose sensitivity and never recover if the sensor absorbs organic silicon steam. Sensors must be avoid exposing to silicon bond, fixature, silicon latex, putty or plastic contain silicon environment. 1.2 High Corrosive gasIf the sensors are exposed to high concentration corrosive gas (such as H 2S, SO X , Cl 2, HCl etc.), it will not only result in corrosion of sensors structure, also it cause sincere sensitivity attenuation. 1.3 Alkali, Alkali metals salt, halogen pollutionThe sensors performance will be changed badly if sensors be sprayed polluted by alkali metals salt especially brine, or be exposed to halogen such as fluorine.1.4 Touch waterSensitivity of the sensors will be reduced when spattered or dipped in water. 1.5 FreezingDo avoid icing on sensor’s surface, otherwise sensing material will be broken and lost sensitivity. 1.6 Applied higher voltageApplied voltage on sensor should not be higher than stipulated value, even if the sensor is not physically damaged or broken, it causes down-line or heater damaged, and bring on sensors’ sensitivity characteristic changed badly.1.7 Voltage on wrong pinsFor 6 pins sensor, Pin 2&5 is heating electrodes, Pin (1,3)/(4,6) are testing electrodes (Pin 1 connects with Pin 3, while Pin 4 connects with Pin 6).If apply voltage on Pin 1&3 or 4&6, it will make lead broken; and no signal putout if apply on pins 2&4.Fig7. Lead sketch2 .Following conditions must be avoided 2.1 Water CondensationIndoor conditions, slight water condensation will influence sensors’ performance lightly. However, ifwater condensation on sensors surface and keep a certain period, sensors ’ sensitiv e will be decreased. 2.2 Used in high gas concentrationNo matter the sensor is electrified or not, if it is placed in high gas concentration for long time, sensorscharacteristic will be affected. If lighter gas sprays the sensor,it will cause extremely damage. 2.3 Long time storageThe sensors resistance will drift reversibly if it’s stored for long time without electrify, this drift is related with storage conditions. Sensors should be stored in airproof bag without volatile silicon compound. For the sensors with long time storage but no electrify, they need long galvanical aging time for stability before using. The suggested aging time as follow:Stable2.No matter the sensors electrified or not, if exposed to adverse environment for long time, such as high humidity, high temperature, or high pollution etc., it will influence the sensors’ performance badly. 2.5 VibrationContinual vibration will result in sensors down-lead response then break. In transportation or assembling line, pneumatic screwdriver/ultrasonic welding machine can lead this vibration. 2.6 ConcussionIf sensors meet strong concussion, it may lead its lead wire disconnected. 2.7 Usage Conditions2.7.1For sensor, handmade welding is optimal way.

氨气传感器原理
氨气传感器原理氨气传感器是一种用于测量空气中氨气浓度的仪器，它可以广泛应用于农业、环境保护、工业等领域。
传感器的原理是基于氨气的电化学反应，在电极上产生电流或电压信号，进而测量氨气浓度。
本文将介绍氨气传感器的原理及其应用。
氨气传感器主要使用的传感元件是氨气电化学传感器，它利用氨气的电化学反应测量氨气的浓度。
一般来说，氨气电化学传感器由三个基本部分组成：工作电极、参考电极和电解质。
1. 工作电极：在氨气溶液中，工作电极表面的铂金属上发生氧化还原反应，其中氧化反应是把氨气氧化为氮气，还原反应是把氧气还原为水。
这些反应产生的电流或电势与氨气浓度成正比。
2. 参考电极：参考电极通常使用银/银氯化物电极或银电极。
3. 电解质：电解质通常是含有钾离子的盐水溶液，它的主要作用是传递离子电流。
当氨气接触到工作电极时，它会发生电化学反应，产生电荷，并且改变电化学反应的方向。
在测量过程中，电解质中的外部电源引起的电流可以表示氨气与铂电极之间的交互作用。
随着氨气浓度的增加，工作电极中反应的速率随之增加，电位变化也随之增大。
电位或电流的测量可以被用来评估气体浓度。
二、应用领域1. 农业：氨气传感器可用于测量畜禽场等场所的氨气浓度，帮助农民了解空气质量，保护动物健康，减少氨气的挥发和排放，改善环境质量。
2. 工业：氨气传感器可以用于化学处理、卫生清洁、医药制造和其他工业应用中氨气检测，以保护工人健康和安全，防止化学品泄漏和火灾等意外事故发生。
3. 环境保护：氨气传感器可用于测量高氨气浓度的空气污染源，例如农场、污水处理厂、化肥工厂、垃圾填埋场等，掌握状况，制定控制策略，减少氨气排放对环境的影响。
4. 医学：氨气是肝脏疾病的重要生物指标，它能够反映肝脏的代谢活动和功能状态。
利用氨气传感器可以测量人体呼出气中的氨气浓度，从而诊断肝脏疾病。
氨气传感器具有测量范围广、响应时间快、灵敏度高、可重复使用等优点，可以满足不同领域的需求，为实现环保和保障人的健康发挥重要作用。
