Compare adjustable, Mini and Digital Grove PIR sensors, wire them for ESP32 3.3 V logic and read motion without an extra Arduino library.
Features
🌱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
Description
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.
Note:
Please note that the orientation can influence the sensitivity, for more accurate detection, please place the sensor as in the picture below.
