The energy consumption of a heating, ventilation, and air conditioning (HVAC) system represents a large amount of the total for a commercial or civic building. In order to optimize the system performance and to increase the comfort of people living or working in a building, it is necessary to monitor the relevant parameters of the circulating air flux. To this end, an array of sensors (i.e., temperature, humidity, and CO percentage sensors) is usually deployed along the aeraulic ducts and/or in various rooms. Generally, these sensors are powered by wires or batteries, but both methods have some drawbacks. In this paper, a possible solution to these drawbacks is proposed. It presents a wireless sensor node powered by an Energy Harvesting (EH) device acted on by the air flux itself. The collected data are transmitted to a central unit via a LoRa radio channel. The EH device can be placed in air ducts or close to air outlets.
供暖、通风与空调（HVAC）系统的能耗在商业或民用建筑的总能耗中占比很大。为了优化系统性能并提高建筑物内居住或工作人员的舒适度，有必要监测循环空气流量的相关参数。为此，通常会沿着风道和/或在各个房间部署一系列传感器（即温度、湿度和一氧化碳百分比传感器）。一般来说，这些传感器由电线或电池供电，但这两种方法都有一些缺点。本文提出了一种解决这些缺点的可能方案。它展示了一种由能量收集（EH）装置供电的无线传感器节点，该装置由空气流量本身驱动。收集到的数据通过LoRa无线电信道传输到中央单元。EH装置可以放置在风道中或靠近出风口的位置。
