ABSTRACT
This research uses an IoT chip to integrate with sensors, temperature control systems, and so forth to construct a hot water remote monitoring system. The system can monitor the water temperature of the heating system using a mobile phone application (app), and upload and record the water temperature to a cloud server. The system contains: (1) a heating system: heater, temperature display, relay, and so forth; (2) a remote monitoring system: including server, mobile phone monitoring app, network monitoring system, Bluetooth or Wi-Fi module; (3) a hot water system: including inner and outer tank and a heat preservation device; (4) IoT chips: containing Arduino chip control cards and other communication protocols. The system can be used for heating systems for large companies or hot water systems for home use, and for remote control and data access through the mobile app. Monitoring through the mobile app can have the following advantages: (1) remote access to the system for heating, recording and querying usage status. The data stored in the cloud can be used for an analysis of energy efficiency and guide policy decisions for the company’s energy consumption. (2) Remote monitoring through the mobile phone app can be used to determine whether any repairs are required to the heating system. (3) Through the use of the statistical data, the heating temperature can be adjusted, and the system can be optimized according to time and temperature changes, which can save energy. The network monitoring management, temperature sensing and control, and data access control of the app are used in this research. The average control temperature error is 3% after experimental analysis. The data access time error value is three seconds. The data access stability is over 99%.
