3MINI SENSING MODULE HC-SR505

Description

The HC-SR505 Mini PIR Motion Sensor Module is a compact infrared sensor designed for motion detection applications. Using passive infrared (PIR) technology, it detects human body movement within its sensing range and outputs a high-level signal. With low power consumption, small size, and high reliability, it is widely used in security systems, lighting control, and automation projects.

Features

Low-power consumption Output level: High 3.3V / Low 0V  Trigger: repeatable trigger (default)Automatic induction: to enter the sensing range of the output is high, people leave the sensor range automatically delay off high, output low. Ultra-small size.

Repeatable trigger: the sensor output high, the delay period, if there is human activity in its sensing range, the output will remain high until people leave after the high variable delay Low (automatically extended sensor module detects the human body after every activity a delay period, and the last time an event is the starting point of the delay time).

Wide operating voltage range: the default operating voltage DC4.5V-20V. Micropower: quiescent current <50 microamps, especially for battery-powered automatic control products. Output high signal: easy docking and all kinds of circuits.
