Hi,

I bought TDS tester and after some test with electronic card I found the output data (see photos).
The first one is when the tester shows 0 and the second picture is when shows 102.

How can I read his data on an arduino?

Thank you very much for your help !!

Can you post a link describing the data send by the tester?

I found this page who explain what kind of tester is it : https://www.dhgate.com/product/lcd-display-digital-multifunctional-measure/251918928.html

Hope this information can help you to help me :-)

The only technical data there is the price and the note the device is no longer available for sale. What did you find that I missed?

Sorry, I thought you wanted the references of the product...

The module does not send any data, I was able to have them by welding on pins of the microcontroller (they have no reference) wire. I was able to find the good pins sending to another microcontroller (still no reference) for displaying data.

Have you seen similar data ? If yes, how can I read this with an Arduino ? I don't know where to start for reading this data.

These are not designed to be read by an Arduino or other MCU.
You may be able to reverse engineer the code - start by doing an accurate timing of the signal and see if there are any patterns. Then try to link those patterns with temperature/EC readings. In the end you may be able to decode it.
There are much simpler ways to read EC with an Arduino...
