## Description

A compact passive infrared (PIR) motion sensor that detects movement from people and animals at distances of 2 to 5 metres. Much smaller than standard PIR modules, this sensor is ideal for unobtrusive projects and plugs directly into a breadboard or perfboard. Powered from 3–12 V DC via an onboard regulator, the sensor outputs a 3.3 V digital signal that goes high when motion is detected and stays high for approximately 2 seconds, giving your microcontroller plenty of time to read the state. Key Features Compact Form Factor – Breadboard and perfboard friendly with 3-pin header Wide Input Voltage – 3–12 V DC with onboard regulator 3.3 V Digital Output – High when motion detected, low when idle 13.8 mm Diameter Lens – 100° detection spread, 2–5 m range 2-Second Hold Time – Signal stays high after detection for easy reading Pinout Pin 1 (−) – Ground Pin 2 (O) – Signal output (3.3 V high/low) Pin 3 (+) – Power (3–12 V DC) Tip: When using with a Raspberry Pi, keep the PIR sensor physically away from the Pi to avoid false triggers. Ideal For Motion-activated lighting and alarms Presence detection in IoT projects Breadboard prototyping with Arduino or Raspberry Pi Package Contents 1× Mini PIR motion sensor with 3-pin header and lens Resources PIR Sensor Tutorial (Adafruit Learn)
