This mini doppler radar sensor module is equipped with supporting DC 4-28V wide voltage,It will automatically continuously output the high level TTL signal when there is motion. 360 degree no blind angle detection and maximum 7m sensing distance.
It is perfect for DIY microwave motion sensor light switch, human sensor toys, smart security devices, etc.
Power up the sensor by 5VDC using pins “VIN” and “GND”.
It can handle anywhere from 4v-28v in, which it then converts and outputs 3.3v to the 3V3 pin. This pin can be utilized for a multitude of tasks, such as an LED to indicate power, or even to supply power to a mini 3v based MCU.
*Notes– The right ahead of induction side should’t place any metal to block. The front/back side should reserve more than 1cm space
