IR sensor motion detectors provides an effective, efficient, and convenient way to improve security in variety of settings, and therefore are commonly used in security systems, automatic doors, and other applications where the detection of motion is required. Here is a typical case of microcontroller-based motion detector.  

The Infrared motion detector is consisted of a transmitter, a receiver, LED lights, and lens. It works by emitting a beam of infrared radiation and then measuring the amount of reflection or absorption that occurs when the beam is interrupted by a moving object. The sensor then sends a signal to the device it is connected to, such as an alarm system or lighting control, to trigger a response.   

Main features:

1.Detection range: 100m

2.Beams: 2 beams active

3.Optical Source: Infrared digital pulse mode

4.Response Speed: 50～700ms

5.Alarm Output: NC&NO contact rating AV/DC 30V/0.5A

6.Alarm Output-bus: MA bus across wave carrier model

7.Input Voltage: DC 9～24V

8.Current: 65mA
