Arduino Controlled Air Conditioner

Summers are here and how! This project was born out of the need to be able to control an old school window AC right from your desk, obviously it didn’t come with a remote control. You will be needing an Arduino Uno, Tower Pro MG995 servo driven mechanism to activate the AC, a DS18B20 temperature sensor, and MegunoLink Pro to set the control points. MegunoLink is a Windows Application for receiving and sending serial data. You can use it to visualize the information in an interactive manner.

To start with, you will need a mechanical actuator to control the AC switch. And a 3D printer to print it. Arduino controls the hardware with the help of the capacitor. The software records the current temperature value and if it falls below that, it will switch off the AC.

To configure the temperature controller, an interface was custom built using MegunoLink’s Interface Panel visualizer. You can get the details in the link. You can use it to change the highest and lowest temperatures. You can use it later, to check the temperature ‘history’ as well.

You can see how to set the servo and download the required libraries from the link below.
