In this tutorial we will check how to create a very simple alarm system with a buzzer and a PIR motion sensor. We will be using the Arduino core, running on the ESP32. The tests were performed using a DFRobot’s ESP32 module integrated in a ESP32 development board, and a DFRobot’s PIR sensor module. Introduction In this tutorial we …

In this tutorial we will check how to interact with a PIR motion sensor using an interrupt based approach, using the Arduino core running on the ESP32. The tests were performed using a DFRobot’s ESP32 module integrated in a ESP32 development board, and a DFRobot’s PIR sensor module. Introduction In this tutorial we will check how to interact with …
