Abstract

Nowadays engineers are widely inventing modern technology in which new technologies will be introduced around the world every day that will make human life efficient. The Internet of Things (IoT) is one of the most ground-breaking inventions ever devised by engineers all over the world. The wireless automation system is one of the IoT applications that allows for real-time control and monitoring of home appliances through the Internet. This project is developed to help the users to achieve full time electrical supplies for houses, hospitals, server room’s etc. The main appliances such as refrigerator, aquarium oxygen tank, medical supply equipment and aircond are such examples of electrical appliances. In this project, the ESP32 microcontroller is used and programmed to the Arduino IDE. The ESP32 microcontroller will be used to detect and read the input from the current and voltage sensor. At the same time, the ESP32 will process the input signal and inform to the relay to perform the solar output. The users can monitor the voltage, current, power, Kwh and battery backup indicator value from the blynk application. Besides, the users will be informed once the power supply is changed to solar battery backup from the blynk app notification. The blynk application is integrated with the ESP32 Wi-Fi module. The backup supply is from the battery unit. It have been charged from two types of solar panel. Those two types of solar panel is Monocrystalline and Polycrystalline. This two solar panel are used in order to analyze and compare the efficiency of those solar panels different themselves. The analysis of this project is carried out by recording the timing for charging and discharging the solar panels with the battery backup. The benefits from this project will enable the user to monitor the power consumption and to achieve full time power supply more efficiency.
