Air Conditioner Maintenance Alert System Using The Internet of Things Via LINE Notify

Nowadays, air conditioners can be considered electrical appliances that are widely used by people. And there are many people who neglect the maintenance of air conditioners and do not take care of them. The air conditioner will not work at full efficiency and may have an increased electricity consumption rate and additional costs as a result of the dirtiness of the cooling system. The air conditioning system is divided into two main parts: the evaporator set and the condenser set, which coil the coil pipe when used for a long time. Dust will thicken and cause the air conditioner to not cool. Or, if the condenser is dirty, heat will not be able to escape, causing the air conditioner to not cool. It will consume more electricity than usual and may damage the compressor. The organizing team therefore had the idea to monitor air conditioners through the IoT system to help. To notify users about air conditioning maintenance. There will be a sensor system to detect the temperature of the condenser or hot coil and the rate of electricity consumption. Data from the sensors will be sent to the ESP32 as a data transmitter to be stored in the cloud and used to compare the inlet and outlet temperatures of the refrigerant pipes. When the air conditioner has an abnormal temperature or electrical current The system will send a notification message to the mobile phone of the person using this system. So that users can know and contact expert technicians to do maintenance. It also extends the life of the air conditioner
