Design and Implementation of IoT System with Intelligent Solar Charger Controller

Our daily lives have been significantly impacted by the internet. A brand-new, quickly evolving technology called the Internet of Things (IoT) enables electronic devices to remotely perceive and control one another over the internet. The standard criterion for each solar PV cell is maximum power output. Energy storage in off-grid PV systems necessitates the use of a battery charge controller. However, severe weather and frequent variations in load demand can cause the PV power flow provided to the load to vary, decreasing battery charging. The proportional–integral (PI) control MPPT technique was selected for this work. This study uses an Arduino MEGA (microcontroller) to develop a battery charge control system for PV modules. A battery, an Arduino MEGA, sensors, a synchronous buck-boost converter, a Wi-Fi module, a photovoltaic module, and a solar panel are all included in the proposed system. An Arduino-based DHT11 sensor-based automatic temperature management system is designed and implemented in this work. Temperature, humidity, a rain sensor to detect environmental occurrences, and liquid crystal display (LCD) indicators show how weather conditions affect the system under consideration. The results are provided by the DHT11 sensor, which measures the humidity and temperature of the surrounding space.
