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):
Every object with a temperature above absolute zero emits infrared radiation. The HW-416-B contains a pyroelectric sensor split into two halves. hw-416-b pir sensor datasheet
Turning this clockwise increases the detection distance (up to 7 meters). Counter-clockwise reduces it (down to ~3 meters), which is useful for small indoor spaces to avoid false triggers. Adjusts how long the output pin remains HIGH
