Project Description:
Enhanced Battery monitoring module

Need to design a system that will sense and allow monitoring of four variables
(a) Charge level of two Lead acid batteries, (b) presence of AC mains (c) Availability of Sunlight and

provide the output in the form of :

1) % remaining charge of the two batteries (LED output & logic level output)
2) indication of battery charging/discharging status (LED output & logic level output)
3) On /Off status for variables (b) & (c), and an 'ENABLE' output dependent on a logical function of

all the variables being sensed.

* Battery capacity 4Ah to 300 Ah
* Minimal current drain for this monitoring circuit

We can discuss the reference design to be used

Working (demonstrable) circuit with schematic and PCB layout
