Hi FvM. I tried your example, I think it works but this is very sensitive. Parhaps you can advice me for sensitive, how to reduce it?
I put on several capacitor 68 nF between OA Output and Negative but nothing changes for it.
Hi Klaus. Originally I tried with LED and I saw that wasn't a good result which I want to get. After I tried with a photodiode, of course the result is was far batter comparing with LED. At now I'm working with photodiode but result is not accurate for dusk and dark.
Hello. Actually I used a simple LED diode, after I used photodiode and I compared a both. Now I'm using photodiode. Yes you are right for zener diode there was really zener diode. I have a several issue, why do you use in this example OPA353? Perhaps its debends something from it? What's nominal...
Hello I need advice for my solar tracker system. I'm trying to create light sensor using LM358 OA and LED sensor diode. I use controller measurement light signal. I use controller Atmega32 which I connected with OA output (with ADC port). I protect it from high voltage signal with SD. So I want...
