The PIR sensors have a great range of detection and are easy to connect.Great addition to an 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.
