This is a simple to use PIR motion sensor with Grove compatible interface. Simply connect it to Stem shield and program it, when anyone moves in its detecting range, the sensor outputs HIGH on its SIG pin.
The detecting range and response speed can be adjusted by 2 potentiometers soldered on its circuit board, The response speed is from 0.3s - 25s, and max 6 meters of detecting range.
Ready to use with microcontrollers as a digital input. This product also has a compact modular design Plug-and-play grove compatible interface.
In the picture above, the grove shield for Arduino is stacked with Seeeduino V4.2. Of course, you can use that shield with Arduino too :)
*Note: Potentiometers are not included.
