Hi. I’m trying to read ESP ADC input voltage from TDS sensor, but it jumps randomly from 0,300V to 0,450V. The Sensor output voltage is stable (0,438V) according to my multimeter and osciloscope. I connected sensor output to one of ADC GPIOS. Should I do anything else to remove the noise? Is this ES...

I'm having the same problem. Any solution to this?

Thank you
