The HW-416-B is slightly more compact, making it better for wearable or space-constrained projects. hw-416-b pir sensor datasheet

Confirm your board’s marking – some HW-416-B variants swap the naming. The HW-416-B is slightly more compact, making it

The HW-416-B is a passive infrared (PIR) motion sensor module built around the signal processing IC. It is designed for Arduino, Raspberry Pi, ESP32, and other microcontroller (MCU) or relay-based projects. Typical applications include automatic lighting, security alarms, human-activated displays, and energy-saving systems. The HW-416-B is slightly more compact
