Description: These motion detectors emit microwave signals and measure the time taken for the signal to be reflected back to the sensor. A person moving into the detection zone causes a disruption in the microwave beam and trigger.These detect motion through the principle of Doppler radar and are similar to a radar speed gun. A continuous wave of microwave radiation is emitted, and phase shifts in the reflected microwaves due to motion of an object toward (or away from) the receiver result in a heterodyne signal at a low audio frequency.It is mainly used in automatic door control, safety guard system, automatic video control system, etc. This module uses 10.525 GHz band to detect moving. This module is a Non-contact object detection which is independent of temperature, humidity, noise, airflow, dust, light, etc.The output power is low and harmless for human body. The microwave motion detectors feature strong RF interface.
