DESIGN AND DEVELOPMENT OF AIR CONDITIONER (AC) MONITORING AND MANAGEMENT SYSTEM

Abstract

Nowadays, Air Conditioner (AC) has become a more important appliance in our life. The primary reasons behind the AC explosion are gas leakage, blockage in the evaporator and compressor coil, pipelines, and dust in the air filters. Many people have been injured over the years due to AC blasts. This paper developed a system that uses sensor technology and intelligent devices to reduce AC blast. As a result, pipeline leaks or blockage fault detection system was planned and constructed using MQ-02, TTC 103, optical dust sensors for gas detection, temperature detection, and for detecting dust density, respectively. Also, bacteria can be detected through the MQ-3 sensor as it combines with AC refrigerant and produces ethanol. This system is also digitally connected to smart devices (cellphones) and a control device (RM MINI 3) so that users can receive a detection notification at any time and operate AC from any location. By implementing these sensors, the initial target was achieved. The work is low cost and environment friendly.
