Pir Sensor Datasheet [updated] — Hw-416-b

Turning the Tx potentiometer clockwise increases the duration the output stays "High" after motion ends (from ~0.3 seconds up to 5 minutes). Trigger Jumper:

The HW-416-B is a compact, passive infrared motion sensor designed to detect infrared radiation emitted by living beings. It is called "passive" because it does not emit any energy (like lasers or microwaves) but rather detects changes in the ambient IR radiation around it. It is called "passive" because it does not

With a wide operational voltage range and dead-simple digital output logic, the HW-416-B is an essential asset in any maker's hardware toolkit. Connect to a DC voltage source between 4

Power input pin. Connect to a DC voltage source between 4.5V and 20V.

The HW-416-B relies on pyroelectric technology to detect changes in infrared radiation emitted by moving objects (such as humans or pets). Below are the core electrical and physical parameters of the module: DC 4.5V to 20V (Commonly powered via 5V) Static Current Consumption: < 60 A (Ideal for battery-powered projects)

The board features two trimpots. One adjusts the sensitivity (sensing distance), and the other adjusts the delay time (how long the output stays HIGH after motion is detected).
