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：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。

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.

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. Adjust the sensor head position so that the laser beam points to the center of the target area. Turn off the battery pack, and remove the laser sighting accessory from the sensor head.

This document focuses on the issues that need to be taken into account in each phase, in order to minimize the design cost and increase the stability of the product, and to improve the efficiency of the project completion.From hardware circuit reference design, radar antenna and housing layout requirements, how to distinguish interference and multi-functional standard UART protocol output. The radar is a self-contained system.This radar is a self-contained space sensing sensor, which consists of RF antenna, radar chip and high speed MCU. The radar is a self-contained sensor with a combination of RF antenna, radar chip and high-speed main frequency MCU. It can be equipped with a host computer or host computer to flexibly output detection status and data, and meet the needs of several groups of GPIOs. It can be equipped with a host computer or a host computer to flexibly output detection status and data, and meet several groups of GPIOs for user customization and development.1. Working PrincipleThe radar transmits a 60G band millimeter wave signal, and the target reflects the electromagnetic wave signal, and demodulates it from the transmitted signal. The signal is demodulated, then amplified, filtered, ADC and other processing to obtain the echo demodulation signal data. In the MCU unit, the amplitude, frequency and phase of the echo signal are decoded, and the target signal is finally decoded. The target parameters (sleep quality, respiration, tossing, body movement, etc.) are measured and evaluated in the MCU.2. Hardware Design ConsiderationsThe rated supply voltage of the radar needs to meet 4.9 - 6V, and the rated current needs to be 200mA or more input is required. The power supply is designed to have a ripple of ≤100mv.2.1 Power supply can refer to the following circuit designFigure 1Figure 22.2 Wiring DiagramFigure 3 Module and peripheral wiring diagram3. Antenna and housing layout requirementsPCBA: Need to keep the radar patch height ≥ 1mm higher than other devicesHousing structure: need to keep the radar antenna surface and the housing surface have 2 - 5mm distanceHousing detection surface: non-metallic housing, need to be straight to avoid bending surface, affect the performance of the whole sweep surface area PerformanceFigure 44. Electrostatic protectionRadar products with electrostatic sensitive circuitry inside, vulnerable to electrostatic hazards, so need to be in transport, storage, work and handling process to do a good job of electrostatic protection, do not touch the grasp of the radar hands. Therefore, it is necessary to do a good job in the transportation, storage, work and picking up process of static protection, do not touch and grab the radar module antenna surface and connector pins, only touch the corners. Do not touch the surface of the radar module antenna and connector pins with your hands, only touch the corners.When handling the radar sensor, please wear anti-static gloves as much as possible. 5.
