Description
But instead of sniffing the blackbody radiation from a moving person, this sensor uses a microwave Doppler radar technique to detect moving objects. It has a sensitivity range of ~7 meters. When triggered, its TTL-level output (OUT) pin will switch from LOW (0 V) to HIGH (3.3 V) for a finite time (2 to 3 s) before returning to its idle (LOW) state.
This flexible sensor module can easily be used in conjunction with many microcontrollers and even without a microcontroller at all. It can handle power supply inputs anywhere from 4 to 28 V.
The output pin can be utilized for a multitude of tasks, such as for driving an aural/visual indicator or even linking with the I/O of any 3-V microcontroller for further processing. During construction, avoid any metal part in front of the sensor module. Similarly, always keep a minimum of 1-cm clear space on the front and rear side of the module.
