This PIR motion sensor is a small, low-power consumption, and cost-effective sensor ideal for projects requiring short detection distances. Measuring just 20mm x 20mm x 12mm, it has a detection range of 2-5 meters, with 2 meters being the optimal range. This sensor is compatible with Arduino and Raspberry Pi platforms and has an adjustable sensitivity via a reserved pin for a slide rheostat. Its ease of use and small size make it perfect for motion detection in security systems and automated lighting. Features * Adjustable sensitivity: a reserved pin out on board to solder a slide rheostat to adjust the sensitivity * Grove-compatible interface and supports both Arduino and Raspberry Pi platforms * Product Number: Seeed 101020353 Specifications Dimensions 20mm x 20mm x 12mm Weight G.W 8g Sensor Chip S16-L221D Supply Voltage 3.3 – 5V Working Current 12 – 20 μA Sensitivity 120 – 530 μV Max Detecting Range 2m (25℃) Resources * Datasheet * PCBAGrove - Mini PIR Motion Sensor v1.0 Package Contents * 1x Grove - mini PIR motion sensor * 1x 4-pin Grove Cable https://elecena.pl/product/26108918/grove-mini-pir-motion-sensor 2024-06-21 https://elecena.pl/product/26108918/grove-mini-pir-motion-sensor 2024-09-18 https://elecena.pl/product/26108918/grove-mini-pir-motion-sensor 2024-11-29 https://elecena.pl/product/26108918/grove-mini-pir-motion-sensor 2024-11-30 https://elecena.pl/product/26108918/grove-mini-pir-motion-sensor 2025-09-29 https://elecena.pl/product/26108918/grove-mini-pir-motion-sensor 2025-11-28 https://elecena.pl/product/26108918/grove-mini-pir-motion-sensor 2025-11-29
