Abstract

Nowadays, electronic devices have become common in applications. All the electronic devices require energy to function. The chemical energy of the Aloe Vera can be converted to the useful energy. Electrolysis is a process which converts chemical energy into electrical energy. In this project, the electrical energy will be used to power up a wireless switch. Firstly, electrical power generation is characterized from the Aloe Vera with different number of copper-zinc electrode pair. Electrical power from the Aloe Vera is measured and plotted in graph. This mechanism is referred to as self-powering whereby the RF transmitter is powered by the Aloe Vera without battery. A wireless automated watering system for plants will be developed. The copper-zinc electrode pair is inserted into the Aloe Vera to generate output voltage. Power conditioning and storage circuit is designed for storing electrical energy generated by Aloe Vera. The power conditioning circuit is designed to trigger the storage voltage and discharge the voltage to power up the RF wireless switch. After RF transmitter is being turned on, 1 bit RF signal will be send to RF receiver within 10 meter. The RF receiver contains temperature and humidity sensor and automated watering system. Once the RF receiver received 1 bit RF signal, this will trigger the microcontroller unit with WIFI module to read the data from the sensor and send to IoT monitoring system. The watering system will water the plants if the humidity is less than 50%.
