JOY-IT SEN-HC-SR501 PIR-bewegingssensormodule voor Arduino, Raspberry Pi, ESP32

Detect motion with a detection angle of up to 120° and an adjustable range of 3 to 7 meters using the JOY-IT SEN-HC-SR501 PIR motion sensor. This passive infrared sensor module operates on a wide voltage range of DC 4.5V to 20V, making it compatible with Arduino, Raspberry Pi, ESP32, and other microcontrollers.

Overview

The SEN-HC-SR501 is a compact PIR motion sensor module featuring a Fresnel lens and adjustable sensitivity and delay time. It outputs a digital signal (high 3.3V, low 0V) when motion is detected. The trigger mode can be set to non-repeatable (L) or repeatable (H) via a jumper. With a quiescent current of less than 50 µA, it is suitable for battery-powered projects.
