Introducing the Grove – Mini PIR Motion Sensor, a compact and economical solution designed for applications with modest detection distance requirements. Its small form factor makes it a versatile choice for various projects, ensuring seamless integration without sacrificing performance. This sensor strikes a balance between cost-effectiveness and functionality, catering to projects where affordability is a priority. Moreover, the sensor's low power consumption enhances its efficiency, allowing reliable motion detection while extending its operational life. Whether you're working on space-constrained setups or budget-sensitive projects, the Grove – Mini PIR Motion Sensor delivers reliable motion detection performance, meeting your needs with simplicity and effectiveness. 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 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.
