Autonomous WiFi Sensor for Heating Systems in the Internet of Things

الملخص EN

In smart cities and home applications, the use of Wireless Sensor Networks to extract environmental data becomes more common with the passing of time.

These sensors are used for a wide array of applications, but mainly to manage energy consumption in domestic buildings.

One of the key energy consumers in households is heating systems.

To monitor them, sensors are used with wireless communication protocols, like ZigBee, to transmit data to a central processing unit (CPU).

WiFi communications, on the contrary, are rarely seen in these implementations due to its high energy consumption, although almost in every home one can find such networks.

Yet, with the Internet of Things (IoT), new revisions of the standard have arisen which enable this technology for wireless sensing.

To validate this theory and fill a technological necessity, this proposal is presented.

In this work, the design and implementation of an autonomous WiFi sensor, paired with thermoelectric energy harvesting, are presented as an IoT solution for monitoring heating devices.

For this, a thorough analysis of the proposed architecture is presented.

Tests regarding energy consumption and generation, efficiency, and real world scenario trials are done.

Finalizing, a comparison between the obtained results and current implementations is shown.
