The motion detector module is based on infrared technology, automatic control module and LHI778 probe design. This ensures high sensitivity, high reliability and ultra-low voltage operation mode.

It is widely used in various electric auto-sensing devices, especially battery-operated auto-controlled products.

The module is also equipped with a so-called Fresnel lens, a special type of filter that focuses infrared radiation onto the sensor.


  • High sensitivity and reliability
  • Soldered-in jumper for setting temperature compensation
  • Direct switching of relays
  • Ideal for use with microcontroller boards
  • The perfect module for any household
