This project uses ESP32 board and a PIR motion sensor to detect whether the room is occupied. If the room is empty for a long time, the ESP32 board will issue switch-off the outlet command via IFTTT webhook.

You need to update configurations in two files inside the sketch_main directory

cd sketch_main
cp IFTTT_config.h.example IFTTT_config.h
cp WiFiConfig.h.example WiFiConfig.h

Inside IFTTT_config.h file, you need to put in your credentials for IFTTT webhook.

Inside WiFiConfig.h file, you need to update your local WiFi credentials.

Follow Step 3 in this tutorial: https://www.instructables.com/id/ESP32RC522IFTTTHome-Security/

You need to install Arduino IDE and set it up to program with ESP32 board. You can find many tutorials online on how to do that.
