HC-SR505 PIR sensor
Description
The HC-SR505 PIR Sensor is a compact, energy-efficient motion detector designed for precise detection of human presence and motion. It uses infrared technology and possesses automatic control, high sensitivity, high reliability and low power consumption. It triggers a digital output when it senses changes in infrared radiation. It’s 3 pin interface makes it easy to interface with any microcontroller and it’s perfect for motion-activated systems in smart electronics and embedded system projects.
