Hi, I am Designing a PID based Solar Tracker in which i am using 4 LDR connected to each ADC of PIC16f877A,
Kindly Assist me how to manipulate the signals from the LDR sensors for one set point???
hi
if u want do it in PID base it's better U save the curve of each sensor in day light & then do it on sum of these curves
but u can give help via a RTC clock to real set the sun rise time in each day in year
or U can use solar panel as a solar tracker by measuring the voltage & power of it's output
goodluck
