The main objective of this project is to design a solar energy measurement system using IOT for measuring solar cell parameters such as voltage, current and temperature through multiple sensors and upload this parameter values into the thingspeak webpage along with date and time. Solar energy is stored into the rechargeable battery through charging circuit and this battery power is used to switches on the LEDs. The project also includes light sensor which detects the sunlight intensity. The current and voltage sensors are used to measure current and voltage from solar panel. Temperature sensor is used to measuring the temperature. The solar panel is fed to the microcontroller through a potential divider to measure voltage. The system also detects the intensity of sunlight using light sensor and voltage sensor under abnormal conditions of the sunlight the system alerts the user through SMS messages via GSM modem interfaced with the microcontroller. The controlling device of the whole project is Arduino Nano Microcontroller. These parameters as the input value are fed to the arduino nano and then Arduino upload this parameter values into the thingspeak webpage along with date and time through ESP8266 WI-FI module. To perform the task, Microcontroller is loaded with an intelligent program written in embedded ‘C’ language. ThingSpeak is an open-source Internet of Things (IoT) application and API to store and retrieve data from things using the HTTP protocol over the Internet or via a Local Area Network. This IoT device could measure the SOLAR parameters. It continuously monitors the data and updates them to an IoT platform. We can increase the monitoring techniques by making use of advanced technology. In this project we are making use of technology to sense solar energy efficiency using light sensor and voltage sensors so that efficient services can be provided to the solar systems. The system provides SMS alerts using GSM modem to the predefined number under abnormal conditions of the sunlight intensity.
