Intelligent radiant floor heating regulation system with wireless sensors

Abstract

Thermal comfort of person living in building with radiant floor heating is not usually perfect. There is usually absence of control system based on each single room. This work proposes a simple, promising, effective and cost-effective regulation system for radiant floor heating. Designed system is based on small wireless sensors placed in every room to measure the temperature and wirelessly send it to the cloud. The data is analyzed and compared with user selected values and appropriate actions are taken by wireless relay unit that controls flow through each heating circuit by thermoelectric actuators. Main benefits of this system is Internet of Things (IoT) solution, which means that all the computing is made in the cloud. Used sensors and relay board can be relatively cheap due to low demands on its computing power. There is not any expensive main unit with display and user interface, because this system can be controlled via cloud from any kind of device (such as notebook, tablet, smart phone etc.). Prototype have been tested in a normal environment for its basic functions, but more data needs to be measured for final verification.
