Description
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.

Particularities
- 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
