Communication Among Arduino Mega, NodeMCU and Arduino Uno Using Multiple Connections - Upload Data to Blynk IoT

Combine an arduino Mega with Node MCU in order to create an automated application which monitors solar Heater, Humidity and external temperature and provide data to user in order to evaluate if he needs to power the heater in order to increase the water temperature for family needs. Since the power source of the module is Solar Panels , we can also provide data charging logging and also using relays we can add controls in the system.
