Product Description
The motion detector module is based on infrared technology, an automatic control module and LHI778 probe design. This ensures high sensitivity, high reliability and an ultra-recess operating mode.
It is widespread in various electrical auto-sensing devices, especially in battery-operated automatically controlled products.
The module is also equipped with a so -called Fresnellinse, a special type of filter that focuses the infrared radiation on the sensor.

particularities
- High sensitivity and reliability
- Founded jumper to adjust the temperature compensation
- Direct circuit of relays
- Ideal for use with microcontrollers boards
- The perfect module for every household
