{"title":"Mini PIR Sensor with Time and Sensitivity Control - BS612","handle":"mini-pir-sensor-with-time-and-sensitivity-control-bs612","url":"/products/mini-pir-sensor-with-time-and-sensitivity-control-bs612","description":"The BS612 is a compact, fully configurable mini PIR motion sensor that detects movement from approximately 3–8 metres away with a 120° detection spread. Its small form factor makes it ideal for unobtrusive motion-sensing projects where a full-size PIR module would be too bulky.\n\nUnlike basic PIR sensors, the BS612 provides dedicated pins for adjusting both sensitivity and output hold time via simple resistor dividers. The sensitivity can be tuned from most sensitive (0 V on SENS pin) to least sensitive (3.3 V), while the output on-time is adjustable from 2 seconds (0 V on ONTIME pin) up to one hour (3.3 V).\n\nKey Features\n\n\nCompact Form Factor – Much smaller than standard PIR modules with a 4 × 3 mm sensor window\n\nAdjustable Sensitivity – Configure via resistor divider on the SENS pin\n\nAdjustable On-Time – Set output hold duration from 2 seconds to 1 hour via ONTIME pin\n\nEnable/Disable Control – OEN pin to enable or disable the output\n\n3.3 V Operation – Digital output at 3.3 V logic levels\n\nSnap-On Lens – Focused to ~5 m range with 120° spread\n\nFlexible Wires – Breadboard and perfboard friendly\n\n\nQuick Start Wiring\n\n\nPin 1 (SENS) – Connect to GND for maximum sensitivity\n\nPin 3 (VSS) – Connect to GND\n\nPin 4 (VDD/OEN) – Connect to 3.3 V to power and enable output\n\nPin 5 (REL) – Digital signal output\n\nPin 6 (ONTIME) – Connect to GND for 2-second on-time\n\n\nSpecifications\n\n\nOperating Voltage – 3.3 V\n\nDetection Range – ~3–8 m (focused at 5 m)\n\nDetection Angle – 120°\n\nSensor Window – 4 × 3 mm\n\nOutput – 3.3 V digital high/low\n\n\nIdeal For\n\nCompact motion-activated lighting and alarms\nIoT occupancy detection\nBattery-powered motion sensing projects\nDiscreet security and automation triggers\n\n\nPackage Contents\n\n1× Mini PIR Sensor BS612 (with snap-on lens)\n\n\n\nNote: This sensor operates at 3.3 V only. When interfacing with 5 V boards like Arduino, power it from the 3.3 V regulator.\n\n\nResources\n\nAdafruit PIR Sensor Tutorial\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":1924,"title":"Default Title","sku":"AF-5578","price":4.04,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":3,"option1":"Default Title"}]}
