Datasheet - Hw-416-b Pir Sensor
: As passive devices, they do not emit radiation but rather sense it, making them safe and low-power.
Digital output. Stays HIGH (3.3V) when motion is detected and LOW (0V) when idle. Connect to the common ground of your circuit. Adjustable Controls Sensitivity Potentiometer: hw-416-b pir sensor datasheet
If motion is detected while the output is already high, the "delay timer" restarts. The output stays high as long as there is continuous movement. 5. Typical Applications : As passive devices, they do not emit
Clockwise rotation increases the detection distance (up to ~7m), while counter-clockwise decreases it. Delay Time Potentiometer: : As passive devices
