HC-SR505 Mini PIR Motion Sensor – Infrared Body Detector Module for Arduino & Automatic Switch Systems (1-10PCS)
Features:■Automatic induction : to enter the sensing range of the output high, people left the sensing range automatic delay off high , output low.■ ultra-small size .■ repeatable trigger: the sensor output high , the delay period , if there is human activity in its sensing range , the output will remain high until the people left after the delay will be high goes low ( it will be automatically extended after sensing module detects the human body every activity a delay period of time , and with
