Designing control and monitoring system of the air conditioning under internet of things

Currently, there are a record number of air conditioning (AC) systems installed worldwide as a result of rapid population development and rising income of consumer. In order to meet the growing demand for AC, billions of dollars have been invested in infrastructure, and billions of tons of carbon dioxide have been released into the atmosphere. The purpose of this research is to design control and monitoring system of the AC. To achieve this goal, internet of things is applied to control and monitor the AC load and temperature. There are three kinds of sensor to support in this system, such as: PZEM, PIR and DHT22. According to the findings of this research that the cost saving can be achieved 1119.87 IDR when the AC operate during 5 hours.
