SUBALIGU Pyroelectricity Adjustable Pyroelectric Compatible Review

HC--SR501 Body Sensor Module, PIR motion sensors have the jumper breakout for dual-mode operation (as pictured). Works with any SOC, MCU or can even work stand-alone to build quick-n-dirty motion-activated lights, cameras or w/e. The automatic sensor, to enter the sensor output range is high, people leave the sensor range of the automatic delay off high, output low, the PIR sensors have a great range of detection and are easy to connect.Great addition to an Arduino projects. Passive infrared detector(PID) worked perfect for automatic light with MQTT and Lua and esp8266 wifi set up with a home assistant hub. These are adjustable motion sensors, which have small helpful potentiometers/pots on board to adjust on-time and sensitivity.They work well and do not need a library to run. These little infrared sensor modules for general motion detection of up to 15 feet and almost never give a false alarm.The human body sensor lighting industrial automation and control, etc.Ideal for Arduino, Raspberry Pi, PIC and more.
