The SR602 is a PIR (passive infrared detector) sensor that offers accurate detection and reliability, making it ideal for security applications. Consider, for example, switching on an outdoor light when someone approaches or securing rooms in your house house.
The sensor is designed to prevent false detection, is compact and has a low idle consumption, making it a great fit for any IoT project. Connecting the sensor is simple and the supply voltage range is large so that it can be used in combination with any microcontroller.
Useful to know:
The PIR602 will switch a voltage of 3.3V to the output for 2.5 seconds upon detection. To help you get started quickly, we've written an example code [link github] for Arduino and created a YAML file for Home Assistant so you can get started right away!
