Check ADC resolution in ESP32 #10

Assuming 10-bit in code - not sure if this is correct

See what it is by default
See if it can be changed in Arduino Core to 12-bit

Apply 3.3V to analog pin, see if it reads 1023 or 4095. Change to 12-bit The goal of this is to get a full sign wave before processing and calculating RMS

We were initially using Arduino MEGA for testing which had a 10 bit ADC, the code has been moved to Bee Data Logger with a 12Bit ADC , Datalogger.py is run which reads the data from serial and saves it on a CSV file .
