2017 - Temperature Monitoring System
In this work, we present a flexible and multi-probe temperature measurement system, suitable for real time monitoring and long-term applications. The proposed sensor system allows to investigate the thermal performance of different environments such as building areas, walls or external places. The equipment has been characterized both at device and system levels and validated through experimental tests through a comparison with different sensors. The conceived system consists of a control unit with a microcontroller, a user interface and an internal recording section for data storage and management, and digital temperature sensors with a 12-bit resolution, whose number can be freely defined, having the system a modular architecture. The low-cost and open-source characteristics, beyond of its flexibility and capability to manage several sensors placed also very far from the control unit (up to 500 m), make the proposed solution a suitable candidate to be used for practical applications that require on-field measurements.
