When motion is detected, the output goes HIGH. If the target keeps moving within the detection area before the delay time expires, the timer resets, keeping the output HIGH continuously until the target leaves. Interfacing HW-416-B with Arduino

Passive Infrared Sensor - an overview | ScienceDirect Topics ≈ 65mA (active), low quiescent current Detection Range:

When motion is detected, the output goes HIGH. Even if the target keeps moving, the output drops to LOW once the delay timer expires.

It was set to the center, which meant the sensor would stay active for three minutes after one tiny movement. With a small screwdriver, he turned it fully counter-clockwise, reducing the delay to a snappy three seconds. The Sensitivity Pot: Delay Time: Adjustable from ≈ 5 seconds to 5 minutes

: As passive devices, they do not emit radiation but rather sense it, making them safe and low-power.

A small jumper (often marked and L ) selects the trigger mode:

Motion detection is a foundational element of modern automation, security systems, and smart home technology. Among the various tools available to hobbyists and engineers alike, Passive Infrared (PIR) sensors are the most popular for detecting human presence. While many are familiar with the classic HC-SR501, the has emerged as a highly reliable, compact, and efficient alternative.
