sr602人体感应模块代码【原创版】目录1.介绍 SR602 人体感应模块2.SR602 人体感应模块的工作原理3.SR602 人体感应模块的代码编写4.SR602 人体感应模块的应用领域正文一、介绍 SR602 人体感应模块SR602 人体感应模块是一种红外热释传感器，它能够检测到人体发射的红外辐射。

该模块具有灵敏度高、反应速度快、抗干扰能力强等优点，广泛应用于智能家居、安防监控、医疗保健等领域。

二、SR602 人体感应模块的工作原理SR602 人体感应模块基于热释电效应原理工作。

当人体进入模块的检测范围时，人体会发射红外辐射，这些辐射被模块接收并转换为电信号。

电信号的大小与红外辐射的强度成正比，因此当人体进入检测范围时，模块输出的电压会相应地发生变化。

三、SR602 人体感应模块的代码编写以下是一个基于 Arduino 的 SR602 人体感应模块代码示例：```c// 定义模块连接的引脚const int sensorPin = A0;void setup() {// 设置传感器引脚为输入pinMode(sensorPin, INPUT);}void loop() {// 读取传感器引脚的值int sensorValue = analogRead(sensorPin);// 判断传感器值是否超过阈值if (sensorValue > 600) {// 当人体进入检测范围时，执行相应操作Serial.println("人体进入检测范围");} else {// 当人体离开检测范围时，执行相应操作Serial.println("人体离开检测范围");}// 等待 100 毫秒，进行下一次循环delay(100);}```四、SR602 人体感应模块的应用领域SR602 人体感应模块广泛应用于各种场景，例如：1.智能家居：用于自动控制照明、空调等设备，实现节能和人性化家居环境。

AD602：

AD602：双通道、低噪声、宽带可变增益放⼤器（增益范围-10 dB⾄+30 dB）AD600/AD602均为双通道、低噪声、可变增益放⼤器,并针对超声成像系统应⽤进⾏了优化,但同样适⽤于任何要求精确增益、低噪声、低失真和宽带宽的应⽤。

每个独⽴通道均提供0 dB⾄+40 dB(AD600)/-10 dB⾄+30 dB(AD602)增益。

AD602的增益较低,可改善输出的信噪⽐(SNR)。

不过,两款产品均具有相同的1.4 nV/√Hz输⼊噪声谱密度。

dB增益与控制电压成正⽐关系,经过精密校准,⽽且不随电源电压和温度⽽变化。

为实现⾼难度的性能⽬标,ADI公司开发出⼀种专有电路形式X-AMP®。

X-AMP的每个通道均含有0 dB⾄-42.14 dB可变衰减器,后接⾼速固定增益放⼤器。

这样,放⼤器永远不必处理较⼤输⼊,并且还可以利⽤负反馈来精确定义增益和动态范围。

衰减器以7级R-2R梯形⽹络的形式实现,具有经激光调整⾄±2%的100Ω输⼊电阻。

触点之间的衰减为6.02 dB,增益控制电路提供这些触点之间的连续插值,由此便可获得以dB为单位的线性控制功能。

增益控制接⼝为完全差分接⼝,提供约15 MΩ的输⼊电阻以及由内部基准电压定义的32 dB/V(即31.25 mV/dB)⽐例因⼦。

此接⼝的响应时间不到1 µs。

每个通道还具有独⽴的选通设置,可以选择性阻⽌信号传输,并将直流输出电平设置在输出地电压的数毫伏范围以内。

选通控制输⼊为TTL/CMOS兼容。

AD600的最⼤增益为41.07 dB,AD602的最⼤增益为31.07 dB；两种型号的-3 dB带宽标称值均为35 MHz,基本上与增益⽆关。

1 V均⽅根输出和1 MHz噪声带宽的SNR典型值为76 dB(AD600)/86 dB(AD602)。

在100 kHz⾄10 MHz范围内,振幅响应平坦度为±0.5 dB；超出此频率范围时,所有增益设置的群延迟变化幅度均⼩于±2 ns。

注意：电源可采用隔离、非隔离的恒流或恒压电路，只需保证输出电压的波动范围在额定值内。输出电源波动不要大于20%，以免误触发。如果需要黑夜工作，可以将CDS端通过光敏电阻连接到地。
与红外产品比较：微波开关感应距离更远，角度广，无死区，能穿透玻璃和薄木板，根据功率不同可以穿透不同厚度的墙壁，不受环境、温度、灰尘等影响，在 37 度情况下，感应距离不会缩短。微波雷达开关抗干扰能力强，几乎不受风、热等外界环境因素的干扰。
默认设置为连续触发模式。默认设置延时为 2 秒，可以改成 30 秒默认设置为全天工作。

Plug & lock-in the male connector to the mating female connector on the aluminum housing.Power & Output Connection - Open the cover of the main aluminum housing. Slide the cable through the strain relief and connect the wires to the terminal block on the board as shown in Fig. 2-1.

Here are the important components on the board:(1) - Terminal Block for Power & Output connections(2) - Single Turn Potentiometer to adjust Emissivity in tenths (0.x_)(3) - Single Turn Potentiometer to adjust Emissivity in hundreds (0._x)(4) -Slide switch to select between real time (Normal Operation) and alarm set point(5) - Alarm set point adjust, P4(6) - Sensor Head connection(7) - Input Zero adjust, P3(8) - Input Span adjust, P2(9) - Output Zero adjust, P5(10) - Output Span adjust, P6Figure 3-1. Main PC Board3.2Ambient TemperatureThe Sensing head can operate in an ambient temperature of 0 to 70°C (32to 158°F). The Sensing head in the high temperature model (-HT) can operate in an ambient temperature of 0 to 85°C (32 to 185°F) without any cooling required. The Sensing head can operate up to 200°C (392°F) using the water cool jacket accessory OS100-WC (See Fig. 3-6).There is a warm up period of 3 minutes after power up. After the warm up period, temperature measurement can be made.When the ambient temperature around the sensor head changes abruptly,the sensor head goes through thermal shock. It takes a certain amount of time for the sensor head to stabilize to the new ambient temperature. For example, it takes about 30 minutes for the sensor head to stabilize going from 25°C to 50°C (77 to 122°F) ambient temperature.The sensor head dimensions are shown in Fig. 3-2.Figure 3-2. Sensor Housing3-23-33.3Atmospheric QualityEnvironments with smoke, dust, and fumes dirty up the optical lens, and cause erroneous temperature readings. To keep the surface of the optical lens clean, the air purge collar accessory is recommended, OS100-AP , See Fig. 3-7.3.4Measuring TemperatureBefore starting to measure temperature, make sure that the following check list is met:ߜ The power and analog output connections are made (Fig. 2-1).ߜThe sensor head is connected to the main unit.ߜThe slide switch (SW1) on the main board is set to real time (Fig. 3-1).ߜThe target is larger than the optical field of view of the sensor head (Fig. 3-3).ߜThe emissivity adjustment on the main board is set properly (Fig. 3-1).ߜThe output load is within the product specification.On OS102 transmitters, follow these additional steps:ߜ The temperature display is set to °F or °C (Fig. 3-4)ߜ For 4-20mA output models, make sure an output load is added, ie. 250ohms.Figure 3-3.

Here is an exampleof an alarm setting.• An OS101-MA(4/20 mA output), the alarm is to be set at 400°Ftemperature.• Connect the alarm output as shown in Fig. 2-2.• Set the slide switch (SW1) on the main board to the Alarm position.• Measure the analog output, and set the Potentiometer P4 until theoutput reads 10.4 mA which is 40% (400°F) of the temperature range.40 x (20-4)[10.4mA=+ 4]100• Set the slide switch (SW1) back to the Real Time position.• If the temperature reading is below the alarm set point, the alarmoutput stays high, otherwise it goes low.On the OS102, you can set the alarm set point directly based on thetemperature display.3.6Adding Extension CableYou can add extension cable between the Sensor Head and the mainelectronic housing up to 15.2 m (50 feet). After adding the extension cable,the Zero input potentiometer, P3 may be re-adjusted.

This accessory is only used for alignment of the sensor head to the target area.After the alignment process, the accessory has to be removed from the front of the sensor head before temperature measurement.The laser sight accessory is powered from a small compact battery pack (included with the accessory). Connect the battery pack to the accessory using the cable provided. Aim at the target, and turn on the battery power using the slide switch on the battery pack.

九、应用信息
1、振荡器工作频率计算
LD602仅需一个外接电容CT和一个上拉电阻RT即可设置振荡器的工作频率，上电后通过上拉电阻RT对CT电容进行充电，当电容上电压充电到0.6Vdd电压时，双门限比较器动作开启内部下拉27K电阻对CT进行放电，当电容上电压放电到0.4Vdd时，双门限比较器动作关闭内部下拉电阻，CT电容再一次通过上拉电阻RT进行充电到0.6Vdd，这样周期性的对电容进行充放电，从而得到稳定的工作振荡频率，近似的工作频率和电阻电容之间关系由公式TOSC=0.4CTRT*RT/RT-27决定，(电阻单位为K,电容单位为nF,Tosc单位为uS)，频率由f=1⁄TOSC确定，如RT=680K,CT=1nF时，对应的延时时间约为30秒。

选择上拉电阻RT时，需大于80K以上的电阻。

（内置27K电阻可能会在后续版本中修改，请关注最新版的Datasheet）.
振荡器内部工作原理
2、触发延时时间定时器和触发封锁时间定时器
LD602定义触发延时定时器的时间为Tx，触发封锁时间定时器的时间Ti，两者的比例系数为K，即K=Tx/Ti,LD602的K值默认为14，封装为SOP8封装，为适应不同的应用场合，如有其他K值需要（3<K<48）请咨询本司销售。

触发延时时间定时器主要用于信号触发后进入持续输出高电平时间阶段，其定时时间约为100000个Tosc时钟周期，即Tx为固定的100000TOSC，经100000个Tosc时钟周期后，OUT引脚开始输出低电平进入触发封锁时间定时器阶段，触发封锁阶段OUT引脚是持续输出低电平，但振荡器继续工作直至Ti结束。

触发延时和封锁延时
3、可重复触发和不可重复触发功能
当引脚A=”0”时，工作方式设置为不可重复触发模式，所谓不可重复触发模式指的是当Vc高电平有效时，触发信号Vs的第一个上升沿跳变将使OUT脚输出高电平，芯片进入Tx触发延时定时和Ti触发封锁定时阶段，在此阶段内如果再来Vs触发信号，Vs触发信号
将是无效的，一直到Tx和Ti定时结束，触发信号Vs重新有效
不可重复触发模式
当引脚A=”1”时，工作方式设置为可重复触发模式，所谓可重复触发模式指的是当Vc
高电平有效时，触发信号Vs的第一个上升沿跳变将使OUT脚输出高电平，芯片进入Tx触
发延时定时阶段，在Tx阶段内Vs一直有效，在此阶段内如果有Vs上升沿跳变再次触发，
芯片将重新计数Tx触发延时定时，一直到Tx定时结束才使Vs触发信号无效进入Ti封
锁定时阶段，在Ti封锁定时结束后，触发信号Vs才重新有效。

可重复触发模式
4、PIR红外热释电应用建议
一般最常用的热释电红外传感器的灵敏度是沿长方形方向横向移动才是最高的，所以为了在各个方向灵敏度相近，成品在装配布置时，建议采用45度安装，并且使用菲涅尔（Fresnel）透镜。

热释电红外传感器容易受各种热源，光源，辐射，环境温度等干扰，为了尽量避免误触发，请尽量远离火源、空调、窗口等。

在电路布线上，PIR与其他器件的连线越短越好，多层板布线时，连线下方不要走线，尤其不能走大电流的走线。

PIR感应部分的电路要单独隔离并有单独的接地，探头电源上接一个100nF的电容到地，并尽量与探头电源接近。

如果允许，在电源上串联一个47K电阻，并且并联一个100uF的电解电容，在D/S之间接一个200pF 电容等各种方法，尽量避免干扰信号进入处理芯片。

十、封装消息
LD602用的是标准的SOP8通用封装，在立创商城下载一个SOP8封装就可以用。
