Building a Power subsystem for water level monitoring system for tank. We are using Arduino due and we need to implement solar cell of 5v with battery and backup battery. Batteries are rechargeable for the absence of sun. The solar cell has to work for at least a year without intervention and the back-up power source with enough energy for two days of functionality. As we can see it’s a solar recharger project that We need to build.
