Grove Mini PIR motion sensor

説明

特長

🌱Adjustable sensitivity: a reserved pin out on board to solder a slide rheostat to adjust the sensitivity

🌱Easy to use: Grove compatible interface and supports both Arduino and Raspberry Pi platforms

🌱Mini size: 20mm x20mm x12mm

説明

The detection distance in the datasheet is up to 3m to 5m, however, 2m is the best detection distance that we recommend and 25℃ is the most suitable temperature.

The sensitivity of the sensor is adjustable, there is a reserved pin out on the back of the board so that you can solder a slide rheostat to adjust the sensitivity. If you think the sensitivity is not enough, here is a trick, drag the plastic cap a little up will help enhance the sensitivity.

注：

Please note that the orientation can influence the sensitivity, for more accurate detection, please place the sensor as in the picture below.
