Distributed Sensor-less Self-powered System for Measurement of Temperature Difference
Abstract
The paper deals with a theoretical analysis and a feasibility study on a method for measurement of temperature difference between two objects. An idea of distributed and self-powered system for indirect measurement of ?T is presented. It relies on two nodes consisting of thermoelectric modules (TEMs), instead of dedicated temperature sensors. Therefore, the essence of the method requires a wireless link to exchange data between two points (not necessarily to transfer measured data to a hub). Due to the Seebeck effect, the thermoelectric devices respond with output voltages proportional to temperature gradients. Moreover, in the presented concept the TEMs play also roles of local thermogenerators powering radio transceivers and conditioning electronic circuits necessary to read, process, and send the data. The presented solution can be applied, for example, to automatic control, telemetry systems and heat metering.
