Hw416b Pir Sensor Datasheet Better Jun 2026

The core signal processor that processes the output from the PIR sensor. Potentiometers: Two yellow pots for adjusting sensitivity ( Rsxcap R sub s x end-sub ) and time delay ( Rtxcap R sub t x end-sub

The module pairs a dual-element pyroelectric core (such as the RE200B) with a and an NL-11NH Fresnel lens. This combination creates 17 distinct detection zones across a wide viewing angle. hw416b pir sensor datasheet better

It does not emit energy; it only receives infrared radiation. The core signal processor that processes the output

To ensure reliable operation, the HW416B PIR sensor should be installed: It does not emit energy; it only receives infrared radiation

Adjustable from 5 seconds to 5 minutes (300 seconds) via a second potentiometer.

Repeatable Trigger: The delay timer resets with every new movement detected, keeping the output high as long as there is continuous motion.

The HW-416B PIR sensor is a capable, affordable motion detection module that works brilliantly for a wide range of projects when properly understood. The key to getting better results lies in:
