This Grove - PIR Motion Sensor(Passive Infrared Sensor) can detect infrared signal caused by motion. If the PIR sensor notices the infrared energy, the motion detector is triggered and 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.

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 advance
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, is it possible to adjust sensitivity to about 1 meter?
Hi if you view the WIKI there was told you Measuring Range is 0.1m to 6m. So it is can work on 1m.
hiI have a PIR motion sesnor version 1.1bI'm curious about one of the Specificationsthe Detecting angle: 120 degreeit means the sensing range is in front of the sensor? above the sensor?or both of them?this is not clear in the speci
You can see a white guy onto the board,the sensing range is in front of the guy(vertical direction of the board).
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 # Regards
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
Hi there~ Sorry, could you please tell us more about your problem, I don't get your point.Regards
Hi there~We have tested it for you, and the transparent plastic box will be OK.Regards
Trying to use with Linkit One and Base Shield v2 but only high voltage gets all the time.... what do I'm missing?
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.
