Description:
The motion sensor (1111) detects changes in infrared radiation that occur when there is movement by a person (or object), which is different in temperature from the surroundings. As this sensor detects temperature differences, it is well suited to detecting the motion of people by their body temperature.

This sensor is also characterized by a narrow sensing area. The sensor can be used with any device that has an Analogue Input
