Hw416b Pir Sensor Datasheet Better !full! Direct

The HW-416B (HC-SR501) is a 4.5V–20V DC pyroelectric infrared motion sensor featuring adjustable sensitivity up to 7 meters and a 0.3 to 300-second delay. To improve performance, fine-tune the onboard potentiometers for sensitivity and timing, and ensure the sensor is mounted 6-8 feet high, away from direct heat sources and Wi-Fi interference. For detailed specifications and troubleshooting, see E Control Devices PIR (motion) sensor - Adafruit

Setup Tip:

Users recommend mounting the sensor at least 2 meters high and avoiding placement near heat sources or direct sunlight to prevent false positives.

To get the most out of the HW-416B, you must understand its three-pin interface: The HW-416B (HC-SR501) is a 4

1. High sensitivity: The sensor has a high sensitivity to human body radiation, allowing it to detect movement even at a distance.
2. Low noise: The sensor has a low noise output, which reduces interference and false triggers.
3. Digital output: The sensor provides a digital output signal, making it easy to interface with microcontrollers.
