Hw-416-b Pir Sensor Datasheet Jun 2026

: The sensor is optimized to detect motion frequencies between 0.7 Hz and 30 Hz.

Technical Datasheet: HW-416-B PIR Motion Sensor The is a compact, high-sensitivity Passive Infrared (PIR) sensor module designed for automatic motion detection. It is widely used in DIY electronics, security systems, and energy-saving lighting projects due to its low power consumption and easy integration with microcontrollers like Arduino and Raspberry Pi. 1. General Description hw-416-b pir sensor datasheet

Turning clockwise increases the "ON" time after motion is detected. Tip: Turn fully counter-clockwise for a short (~ second) delay, which is best for initial testing. Trigger Jumper : The sensor is optimized to detect motion

The module typically features three pins, usually marked on the PCB or under the white Fresnel lens: Power input ( is recommended for most applications). OUT: Digital output signal ( 3.3V3.3 cap V GND: Ground connection. On-Board Adjustments Trigger Jumper The module typically features three pins,
