This sensor can detect movement in areas up to 6 ft away.
This sensor detects changes in infrared radiation which 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. The sensor is also characterized by a narrow sensing area. 60cm sensor cable included.
This sensor requires a Phidgets interface device, like the 8/8/8
