To Rolf Varga
Dear Rolf, Please connect your questions with the project, so everyone who has similar questions can follow the conversation.
I need to know more about how and what you have done. Can you post pictures of the sensor that you have constructed and how. To which input of the NANO are you connecting? The NANO has an 8 bits ADC, whereas the ESP32 uses 12 bits, although I don't believe this is the problem. How is your electronics circuit build up?
Best Regards
Pedro
Dear Denis
Thank you for your message , I did not paint or varnish the metal because it is allready chromium plated.
