Hw-416-b Pir Sensor Datasheet ^new^ -

Comprehensive Guide to the HW-416-B PIR Motion Sensor The is a compact, highly efficient Passive Infrared (PIR) sensor module widely used in DIY electronics, security systems, and automated lighting projects . Often categorized alongside the popular HC-SR501, the HW-416-B is favored for its smaller footprint and reliable performance in detecting human or animal movement.

The is a compact Passive Infrared (PIR) motion sensor module, commonly used in DIY electronics projects for detecting human movement. It is essentially a variation of the popular AM312 or HC-SR501 sensors, designed for low-power consumption and a smaller physical footprint. Core Specifications Operating Voltage: 2.7V to 12V DC. Static Power Consumption: (ideal for battery-powered devices). Output Signal: High/Low (3.3V High, 0V Low). hw-416-b pir sensor datasheet
