ESP32 with PIR Motion Sensor using Interrupts and Timers ...

2018-08-03· This tutorial shows how to detect motion with the ESP32 using a PIR motion sensor. In this example, when motion is detected (an interrupt is triggered), the ESP32 starts a timer and turns an LED on for a predefined number of seconds. When the timer finishes counting down, the LED is automatically turned off. With this example we’ll also explore two important concepts: interrupts and timers ...

What is a passive infrared sensor? | Arduino by Example

A passive infrared sensor (PIR) is an electronic sensor that uses infrared radiation to detect variations in its field of are most commonly used as motion sensors; for example, they are used to minimize power consumption by switching off lights and utilities if nobody is at home. They are also used in state-of-the-art burglar alarm systems to trigger a switch when motion is detected.
