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.
Grove compatible interface
Voltage range: 3V–5V
2.0cm x 4.0cm twig module
Detecting angle: 120 degree
Detecting distance: max 6m (3m by default)
Adjustable detecting distance and holding time

Hello, I am sorry but I don't quite understand your question.
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 speci
You can see a white guy onto the board,the sensing range is in front of the guy(vertical direction of the board).
Is this usable outdoors? I'm worried specifically about rainwater.
Hi Richard.Yu can use it outdoors,but take some measures to prevent water is unavoidable.
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.
