IoT Based Smart Home Automation Using Solar Photovoltaic System and Online Time Server

In the global scenario comfortable living conditions with domestic automation has become an essential part of our daily life. Our standard of domestic comfort is directly related to consumption of limited resources. By making our house smart to lift up our comfort zone, we're also managing our necessity of water and electricity in a smart way to minimize wastage and reduce environmental pollution by using alternative source of energy for electricity like solar panels. Automation can be accomplished by incorporating the Internet of Things (IoT). This paper presents the complete design of an IoT based solar power control system and water level control system for smart home automation. The proposed design uses the flexible and user-friendly Blynk platform for measurement and control the required parameters. The sensing of different variables like water level and ambient light conditions are conducted using the NodeMCU-ESP8266 microcontroller board, which allows real time data sensing, processing and controlling final control elements in a smarter way.
