SKU 1606-PIRMOTIONEAN 5410329557812Sensors
Description
The D203S PIR sensor module is a passive infrared motion detector designed for security, automation and home automation applications.
It detects changes in the infrared radiation emitted by moving bodies (people, for example), providing a digital TTL output (HIGH/LOW) that is easy to interface with microcontrollers and boards such as Arduino.
Thanks to its good sensitivity and wide detection angle, it is ideal for alarm systems, automatic lighting and low-power embedded projects.
