Hi
the problem is that after booting my esp32 the voltage is 0.0000 Volt at adc pin 34. so measurement is not working. if i disconnect and reconnect the adc pin the measurement works and i get realistic values.
my sensor is running with 24volts. i use a step up to get the voltage.
whats the problem of my setup?
