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.

Grove - PIR Motion Sensor
This sensor allows you to sense motion, usually human movement in its range. Simply connect it to Grove - Base shield and program it, when anyone moves in its detecting range, the sensor will output HIGH on its SIG pin.
Hi there. Can this be set up to provide a close to a voltage free contact? Ie. replace a dry contact doorbell which currently has zero volts to simply close a circuit? If not do you have pair which can do this? Thanks in advanceQuestion by: admin on 2018-12-18 02:38:59
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.Answer by: admin on 2018-12-18 02:38:59

Hi if you view the WIKI there was told you Measuring Range is 0.1m to 6m. So it is can work on 1m.Answer by: admin on 2018-12-18 02:38:59
I have a PIR motion sesnor version 1.1b
I'm curious about one of the Specifications
the Detecting angle: 120 degree
it means the sensing range is in front of the sensor? above the sensor?or both of them?
this is not clear in the speciQuestion by: admin on 2018-12-18 02:38:58
You can see a white guy onto the board,the sensing range is in front of the guy(vertical direction of the board).Answer by: admin on 2018-12-18 02:38:58
Can you re-add the dials from the 1.1 version? It's nearly impossible to solder R6 to add delay and without that it fires rapidly when used on a Wio + IFTTTQuestion by: admin on 2018-12-18 02:30:20
Hi there~ You can download the Eagle file of V1.1 from here # https://github.com/SeeedDocument/Grove_PIR_Motion_Sensor/blob/master/resources/Grove_-_PIR_Motion_Sensor_Eagle_File.zip # RegardsAnswer by: admin on 2018-12-18 02:30:20
Hello, I wish to adjust the distance of detection. I have to add a potentiometer. where do I have to solder the potentiometer on the board? and witch value? Thank you very muchQuestion by: admin on 2018-12-18 02:29:34
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.

Hi there~ Sorry, could you please tell us more about your problem, I don't get your point.RegardsAnswer by: admin on 2018-12-18 02:23:11
I wish to mount this PIR sensor outside in a waterproof box. Can you please advise what kind of material can be used to cover the sensor that doesnt interfere with the passive infrared and is still suitable for outside (i.e. waterproof and U.V. light stable).Question by: admin on 2018-12-18 02:21:32
Hi there~We have tested it for you, and the transparent plastic box will be OK.RegardsAnswer by: admin on 2018-12-18 02:21:32
Trying to use with Linkit One and Base Shield v2 but only high voltage gets all the time.... what do I'm missing?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.Answer by: admin on 2018-12-18 02:20:51
