Off Grid PV monitoring system (webserver)

The project involves real time data display on a webserver embedded on a WiFi connected microcontroller (ATmega/ rasberry Pi) of 3 analogue variables. The Webpage must be accessible through an IP (provided a static IP connection is available)

The data will be collected from 3 sensors connected to the microcontrollers A/D inputs.

The system must also log the 3 variable values for 30 days with 5 minute sampling. Each day can be accessed from the same webpage and displayed as a trend chart.

I have attached an image of how the home screen should look.

Thank you
