Sensor infravermelho para detecção de presença PIR HC-SR501

In this video, we'll explore a sensor widely used in automation and security systems: the HC-SR501 PIR infrared presence detection sensor. You've probably seen this sensor in alarm systems or in lights that automatically turn on when someone enters a room. But how does it actually work? And how can we use it correctly in our projects?
