众所周知，可以从活植物中收集电能，这些植物可以用作在偏远地区为无线设备供电的潜在可再生能源，在偏远地区替换或充电电池是一项艰巨的任务。因此，从偏远地区（例如在农场或森林地区）中收集电能的电能可能是理想的能源来源，因为这些地区富含活植物。本文提出了电源管理电路的设计，该电源可以利用，存储和管理从芦荟叶叶（Aloe Vera）工厂收获的电能，以触发发射器负载，以供电遥控传感器。电源管理电路由两个部分，即；一个能够用作能源储存库的储能系统，可存储从工厂收获的能量以及电压调节系统，该系统用于根据负载操作来增强和管理能量。实验结果表明，在特定的设置条件下从芦荟中收获的电能可以产生3.49 V和1.1 mA的输出。收获的能量被引导到电源管理电路，该电路可以在无负载条件下将电压提高到10.9 V。电源管理电路提升的植物的收获能量可以自动打开发射器，以激活温度和湿度传感器，以定期测量1.22秒的环境刺激，而TOFF为0.46秒。这证明，这种新的能源与电源管理电路结合使用，可以用于为无线传感器网络供电，以在物联网（IoT）中应用。
It is well proven that electrical energy can be harvested from the living plants which can be used as a potential renewable energy source for powering wireless devices in remote areas where replacing or recharging the battery is a difficult task. Therefore, harvesting electrical energy from living plants in remote areas such as in farms or forest areas can be an ideal source of energy as these areas are rich with living plants. The present paper proposes a design of a power management circuit that can harness, store and manage the electrical energy which is harvested from the leaves of Aloe Barbadensis Miller (Aloe Vera) plants to trigger a transmitter load to power a remote sensor. The power management circuit consists of two sections namely; an energy storage system that acts as an energy storage reservoir to store the energy harvested from the plants as well as a voltage regulation system which is used to boost and manage the energy in accordance to a load operation. The experimental results show that the electrical energy harvested from the Aloe Vera under a specific setup condition can produce an output of 3.49 V and 1.1 mA. The harvested energy is being channeled to the power management circuit which can boost the voltage to 10.9 V under no load condition. The harvested energy from the plants boosted by the power management circuit can turn ON the transmitter automatically to activate a temperature and humidity sensor to measure the environmental stimuli periodically with a ton of 1.22 seconds and toff of 0.46 seconds. This proves that this new source of energy combined with a power management circuit can be employed for powering the wireless sensor network for application in the Internet of Things (IoT).
