Hw-416-b Pir: Sensor Datasheet

detects motion by measuring changes in the infrared levels emitted by surrounding objects Operating Voltage: 4.5V to 20V DC. Voltage Output: High/Low signal (3.3V High, 0V Low). Detection Range: Adjustable up to approximately 7 meters (23 feet). Detection Angle: Less than 120°. Delay Time:

(Default) The output stays HIGH as long as motion is continuously detected, resetting the delay timer with each movement.

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

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).
