How to Interface an Industrial TDS Electrode with Arduino to Read and Display mV Values?
hey guys i bought a Industrial grade conductivity electrode (TDS ) , it has 3 pin ( +ve , gnd , output ) . It returns me value in mV . My application needs to read the electrode using arduino and display its value on serial monitor . Asper online sources i need a circuitry to help me read the value . Can anyone help me with it

You can use this guide here. Majorly when measuring voltage using Arduino you will need an ADC. For this guide each unit of the 1023 bit is equivalent to 4.9mV when using the Arduino.

Hello, you can consider using an op amp to amplify the signal to allow the microcontroller to be able to read it, that is if the output is an analogue value
