| Abstract |
Gases emitted by domestic and industrial boilers significantly contribute to the overall pollution levels of urban environments. Among these gases, carbon monoxide (CO) represents a marker of the efficiency of the combustion processes, and the monitoring of its emissions, even if often neglected, is crucial to improve energy efficiency and environmental safety within a smart city context. This article aims at describing a real-time, remote system for the monitoring of CO emissions of domestic and industrial boilers based on the use of a low-power long-range wide-area network (LoRaWAN) sensor node. In particular, the proposed solution is based on an ad hoc front-end circuit acting as a power-gating system for the rest of the sensor node, exploiting the output of the CO sensor as a trigger to activate the data acquisition and transmission module. Such a solution allows to notably increase the lifetime of the node, allowing its powering using rechargeable Li-ion batteries. Tests were performed on a real boiler in order to demonstrate the validity of the proposed solution. Power consumption of the sensor node was experimentally measured: theoretical analysis demonstrated an ideal lifetime for the sensor node up to two and half years. |
