As the need to monitor agriculture parameters intensifies, the development of new sensor nodes for data collection is crucial. These sensor types naturally require power for operation, but conventional battery-based power solutions have certain limitations. This study investigates the potential of harnessing the natural temperature gradient between soil and air to power wireless sensor nodes deployed in environments such as agricultural areas or remote off-grid locations where the use of batteries as a power source is impractical. We evaluated existing devices that exploit similar energy sources and applied the results to develop a state-of-the-art device for extensive testing over a 12-month period. Our main objective was to precisely measure the temperature on a thermoelectric generator (TEG) (a Peltier cell, in particular) and assess the device's energy yield. The device harvested 7852.2 J of electrical energy during the testing period. The experiment highlights the viability of using environmental temperature differences to power wireless sensor nodes in off-grid and battery-constrained applications. The results indicate significant potential for the device as a sustainable energy solution in agricultural monitoring scenarios.
随着监测农业参数的需求日益增强，开发用于数据收集的新型传感器节点至关重要。这些传感器类型自然需要电力来运行，但传统的基于电池的供电解决方案存在一定局限性。本研究探讨了利用土壤和空气之间的自然温度梯度为部署在农业区域或偏远离网地点等环境中的无线传感器节点供电的潜力，在这些环境中使用电池作为电源是不切实际的。我们评估了利用类似能源的现有设备，并将结果应用于开发一种先进设备，进行为期12个月的广泛测试。我们的主要目标是精确测量热电发电机（TEG）（特别是珀尔帖电池）上的温度，并评估该设备的能量产量。在测试期间，该设备收获了7852.2焦耳的电能。该实验突出了利用环境温度差异为离网和电池受限应用中的无线传感器节点供电的可行性。结果表明该设备在农业监测场景中作为可持续能源解决方案具有巨大潜力。
