Hi All
I am building a new safety system project. In that i have to control some digital input and also i have to monitor various analog values(like temperature,fluid level, oil pressure etc). The micro controller i am using is ATmega32. Now i am planning to isolate the analog values from the ADC input of the controller. I tried with PC817 opto coupler. But the problem is that its not linear with the analog input changes.
Can anyone provide a better solution for this...
