Query about Analog TDS sensor
GODSON 2023-04-22 22:27:16 481 Views1 Replies I brought a TDS sensor today. Do I need to calibrate everytime when I use it. Also after uploading the sample code from Dfrobot, I got 0ppm as the value from sensor. Is there any problem with sensor and after calibrating it will it be ok

The TDS sensor will store the calibration parameter in the EEPROM of your main board.
So you don't have to re-calibrate the sensor every time you use it.
But if you use the sensor on another board, you have to calibrate the sensor again.
