Grove - PIR Motion Sensor
Who Viewed This Also Viewed
This is a simple to use PIR(Passive Infrared) 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.

Hi,Dear.You mean to use PIR Motion Sensor instead of ordinary doorbell button, when close to the PIR Motion Sensor, the bell will ring?If so, you also need to plus a relay to control Sensor.

Hi there~ You can refer to the PDF file of v1.2. And please pay attention to the notice. As you can see, you should add a potentiometer near the lens. This one is for distance control. If you still have problem, please contact our email. Regards ========================================================================= techsupport@seeed.cc

Question by: admin on 2018-12-18 02:20:51
It is an IR sensor. To be able to get a meaningful signal, it must be placed where the background IR is low enough that it doesn't trigger the sensor board (or the optional resistors and pots must be attached and they must be adjusted to reduce the sensor's sensitivity below the background level. To test the sensor, connect and power it, read it out. It will probably be responding to your body, your computers, etc. Place a blanket in the freezer for 15 minutes, then wrap the sensor in it and place an inverted (empty) drawer over the wrapped sensor. This should produce a low signal. (You could also just stuff the sensor in the freezer and shut the door!) If you don't get a low signal, check your wiring! Once you've achieved a low (indicating that it is not "seeing" enough IR to trigger the output) you can expose it to more light or a warm body, and it should respond. PIR sensors are used indoors, usually in unoccupied rooms, so that, when a person enters, it will see they are present by the IR (light emitted from their bodies by body heat) and turn on lights. Simulate this environment to test it.
