On the PCB version often associated with HW-416 codes, there are three pads labeled H , L , and a center pad (often requiring soldering a jumper rather than using a pin header).
| Component | Function | |-----------|----------| | | Adjusts output hold time (clockwise = longer) | | Sensitivity (Rx) | Adjusts detection distance (clockwise = more sensitive / longer range) | | Trigger mode jumper (L / H) | L = single trigger, H = repeat trigger | | Temperature compensation (some modules) | Helps reduce false triggers in hot/cold environments | hw-416-b pir sensor datasheet

In the quiet hum of Leo’s cluttered workshop, a single HW-416B PIR sensor In the quiet hum of Leo’s cluttered workshop,
The sensor uses a simple 3-pin interface usually found under the white Fresnel lens: Connect to 5V power.
The module typically features a 3-pin interface, making it compatible with Arduino, ESP32, Raspberry Pi, and other microcontrollers. Power input (4.5V to 20V).
