Automatically turning on corridor, bathroom, or outdoor pathway lights when someone approaches, saving significant electrical energy.
Adjusts how long the output pin remains HIGH after motion is detected. Range is approximately 0.3s to 300s. Trigger Jumper (Yellow Cap): L (Non-repeatable): hw-416-b pir sensor datasheet
The HW-416-B PIR sensor module typically has three pins:
: The sensor is optimized to detect motion frequencies between 0.7 Hz and 30 Hz. from machine import Pin import time Automatically turning
