Description 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. Specification - Grove compatible interface - Voltage range: 3 ... 5 V - 2.0cm x 4.0cm twig module - Detecting angle: 120 degree - Detecting distance: max 6m (3m by default) - Adjustable detecting distance and holding time Application Ideas - Motion sensor - Thief-guarding System - Switch - Industrial automation For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product. https://elecena.pl/product/9696466/101020020-arduino-grove-pir-motion-sensor-tm2291 2017-08-05 https://elecena.pl/product/9696466/101020020-arduino-grove-pir-motion-sensor-tm2291 2018-01-25 https://elecena.pl/product/9696466/101020020-arduino-grove-pir-motion-sensor-tm2291 2021-05-21 https://elecena.pl/product/9696466/101020020-arduino-grove-pir-motion-sensor-tm2291 2022-10-22 https://elecena.pl/product/9696466/101020020-arduino-grove-pir-motion-sensor-tm2291 2023-08-16 https://elecena.pl/product/9696466/101020020-arduino-grove-pir-motion-sensor-tm2291 2025-02-08 https://elecena.pl/product/9696466/101020020-arduino-grove-pir-motion-sensor-tm2291 2026-02-20
