## 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. Unlike 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). Key Features Compact Form Factor – Much smaller than standard PIR modules with a 4 × 3 mm sensor window Adjustable Sensitivity – Configure via resistor divider on the SENS pin Adjustable On-Time – Set output hold duration from 2 seconds to 1 hour via ONTIME pin Enable/Disable Control – OEN pin to enable or disable the output 3.3 V Operation – Digital output at 3.3 V logic levels Snap-On Lens – Focused to ~5 m range with 120° spread Flexible Wires – Breadboard and perfboard friendly Quick Start Wiring Pin 1 (SENS) – Connect to GND for maximum sensitivity Pin 3 (VSS) – Connect to GND Pin 4 (VDD/OEN) – Connect to 3.3 V to power and enable output Pin 5 (REL) – Digital signal output Pin 6 (ONTIME) – Connect to GND for 2-second on-time Specifications Operating Voltage – 3.3 V Detection Range – ~3–8 m (focused at 5 m) Detection Angle – 120° Sensor Window – 4 × 3 mm Output – 3.3 V digital high/low Ideal For Compact motion-activated lighting and alarms IoT occupancy detection Battery-powered motion sensing projects Discreet security and automation triggers Package Contents 1× Mini PIR Sensor BS612 (with snap-on lens) Note: This sensor operates at 3.3 V only. When interfacing with 5 V boards like Arduino, power it from the 3.3 V regulator. Resources Adafruit PIR Sensor Tutorial
