Energy harvesting technology, which collects natural energy and converts it into electrical energy, is a very important technology for the future energy industry. Solar cells are one of the most popular energy harvesting devices due to their high power and cost-effectiveness; however, because solar cells are highly influenced by weather conditions, they are not suitable for continuously generating electricity. In this paper we propose a new unified harvesting module (UHM), which is thin and lightweight, to harvest natural energy sources in various weather conditions. The UHM consists of two triboelectric nanogenerators (TENG), a transparent one for harvesting energy from raindrop impacts and one for harvesting wind energy, and a solar cell. This device can turn on 62 LEDs in real time without an energy storage device. Additionally, the UHM can be used as a self-powered weather sensor to detect rain drops, sunlight, and wind speed based on its electrical output. From this, the weather monitoring platform was subsequently demonstrated for use on a smart farm using a data acquisition system and LabVIEW software. This work proposes a new generator for not only harvesting natural energy, but also for broadening its application to the Internet of Things by developing practical usage of energy harvesting technology systems.

收集自然能并将其转换为电能的能量收集技术对于未来的能源行业来说是非常重要的技术。太阳能电池由于其高功率和成本效益而成为最受欢迎的能量收集设备之一。但是，由于太阳能电池受天气条件的影响很大，因此不适合连续发电。在本文中，我们提出了一种新型的统一采集模块（UHM），它既轻巧又轻便，可以在各种天气条件下采集自然能源。UHM由两个摩擦电纳米发电机（TENG），一个透明的，用于收集雨滴撞击的能量和一个用于收集风能的发电机以及一个太阳能电池组成。该设备无需储能设备即可实时打开62个LED。另外，UHM可用作自供电的天气传感器，可根据其电输出来检测雨滴，阳光和风速。由此，随后演示了天气监视平台，该平台可通过数据采集系统和LabVIEW软件在智能农场中使用。这项工作提出了一种新型发电机，该发电机不仅用于收集自然能源，而且还可以通过开发实际使用的能量收集技术系统来扩大其在物联网中的应用。
