Design of an on-off control system and a new display via internet based on Arduino Uno with application to window A/C

Abstract

Air Conditioner (A/C) is a system of air conditioning which serves need of thermal comfort inside a room. On one side, it is an advantage. However, on the other side, the energy consumption of A/C is the biggest in household appliances. In this paper, to solve the problem was designed the control system and display of A/C based on Arduino Uno. To do this, the Arduino was uploaded with a program of control system so that it can function as a controller. Whereas, the display as a monitor was designed using the Blynk that is supported a Smart-phone and Internet network. The results showed that the response of designed control system is able to maintain the desired temperature with range of error from 0.0°C to 0.2°C and the A/C can be set and monitored from far away via internet. In addition, although, a client and the A/C were separated by distance, the response was almost not delay and stayed accurate. Moreover, it was predicted that the using of proposed A/C in illustrated situation can save energy by 50%. It can be considered as a promising solution for the energy consumption issues.
