Construction of Indoor Thermal Comfort Environmental Monitoring System Based on the IoT Architecture

Abstract EN

With the development and progress of technology, people’s requirements for living quality are increasingly higher.

This study builds an indoor thermal comfort environmental monitoring system through the Internet of Things (IoT) architecture to explore the thermal comfort of people in indoor environments.

Then, the applicable indicators are selected from a series of thermal comfort pointers, and the controllable indoor environmental parameters are analyzed and simulated on MATLAB to obtain the impact on the thermal comfort indicators, which can serve as important data to set up the fuzzy rule base.

Next, according to the ISO7730 comfort standard and energy saving, three ways to control thermal comfort are proposed.

With Arduino UNO as the development substrate, the sensing nodes for the indoor environment are set up, and the wireless sensing network is configured with ESP8266 to transmit the sensing data to the terminal.

Monitored by the C# human-machine interface, the controllable load is controlled by wireless remote mode.

Finally, the data is stored in the database for follow-up experimentation and analysis.

Through actual measurement experiments, the thermal comfort and energy saving effects, under comfort, general, and energy-saving modes, as proposed in this study, are verified to achieve a balance between thermal comfort and energy saving.
