Hw-416-b Pir Sensor Datasheet ((link)) -
The HW-416-B is a high-performance passive infrared (PIR) motion sensor module, widely recognized as a compatible or upgraded version of the industry-standard HC-SR501. It is designed to detect human or animal movement by sensing changes in infrared radiation levels. Key Technical Specifications PIR Motion Sensor HW416B - Tayda Electronics
Adjusts the detection distance. Turning clockwise generally increases the range. Time Delay (TIME): hw-416-b pir sensor datasheet
Application Circuit Example (Arduino Interface)
To use the HW-416-B with an Arduino Uno or similar 5V logic board: The HW-416-B is a high-performance passive infrared (PIR)
Enclosure: The Fresnel lens (the white plastic dome) must remain unobstructed. If mounting in a box, ensure the dome protrudes through a cutout. Turning clockwise generally increases the range
The module typically features three main pins for connection and two potentiometers for fine-tuning performance. Connect to 5V–20V power source.
As soon as he powered it on, the sensor went haywire. The serial monitor scrolled "Motion detected!" in a frantic loop, even though the room was empty. Remembering a tip from an old forum, Leo checked the distance; the sensor was too close to his Raspberry Pi, and the electromagnetic noise was causing "odd behavior". He moved the sensor five feet away, but it still stayed "HIGH" for way too long.
