Hw-416-b Pir Sensor Datasheet ((new))

The sensor uses a simple 3-pin interface usually found under the white Fresnel lens: Connect to 5V power.

The is a reliable, low-power motion detection module ideal for microcontroller projects requiring a fast response and compact footprint. While an official unified datasheet remains elusive, the specifications and behavior described in this article are based on reverse-engineered measurements and manufacturer-compliant components. hw-416-b pir sensor datasheet

The module typically features a 3-pin interface for easy connectivity: : Power supply input (4.5V – 20V). The sensor uses a simple 3-pin interface usually
