good day all, i'm new in this forum and i hope u guys can help me.

i'm constructing a data logger to monitor solar system. i need to moniter temperature, irradiation,voltage and current. the data will be displayed on PC thru RS232. my circuit and code are attached below..the problem is my system give a non satisfactory output..i dont know what is wrong with the circuit..i hope u guys can help me..for voltage and current sensor i use LA55 and LV25 from LEm which is connected to PV module..thanks a lot

The schematic does not seem to have any sensors for those things you wish to measure. Lacking that, your code can't possibly be related to reading in values for your solar system.
