  • Product Type: HC--SR501 Body Sensor Module
  • Automatic Induction: when someone enters its sensing range, input high; when someone leave the sensor range, automatic delay off high, output low
  • Photosensitive control (optional): module is reserved for the location, you can set the photosensitive control, daytime or light sensing.
  • The photosensitive control optional features not installed at the factory photoresistor. If necessary, please purchase separately photoresistor install it yourself
