Much smaller than standard PIR modules, this sensor is ideal for unobtrusive projects and plugs directly into a breadboard or perfboard.\n\nPowered 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.\n\nKey Features\n\n\nCompact Form Factor – Breadboard and perfboard friendly with 3-pin header\n\nWide Input Voltage – 3–12 V DC with onboard regulator\n\n3.3 V Digital Output – High when motion detected, low when idle\n\n13.8 mm Diameter Lens – 100° detection spread, 2–5 m range\n\n2-Second Hold Time – Signal stays high after detection for easy reading\n\n\nPinout\n\n\nPin 1 (−) – Ground\n\nPin 2 (O) – Signal output (3.3 V high/low)\n\nPin 3 (+) – Power (3–12 V DC)\n\n\n\nTip: When using with a Raspberry Pi, keep the PIR sensor physically away from the Pi to avoid false triggers.\n\n\nIdeal For\n\nMotion-activated lighting and alarms\nPresence detection in IoT projects\nBreadboard prototyping with Arduino or Raspberry Pi\n\n\nPackage Contents\n\n1× Mini PIR motion sensor with 3-pin header and lens\n\n\nResources\n\nPIR Sensor Tutorial (Adafruit Learn)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3435,"title":"Default Title","sku":"AF-4871","price":8.04,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
