Check the code on there Wiki
Great product, easily connected with my Raspberry Pi with an additional ADS1115, be sure check there wiki for the code.

Good probe, but some IMPORTANT TIPS....
Works well. Some tips...- Download and Use the GravityTDS.h library instead of using the sample code. MUCH simpler and easier to implement.- Remember to pull off the cover from the tip of the probe! I didn't even notice the probe cover for the first 20 mins of trying to get it to work.- For most accurate results, buy a separate temperature probe and code your project to have the temperature sensor provide the temperature compensation value for the TDS sensor.

works
actually works and does what its supposed to do.

Inaccurate and poor information
This is the same TDS meter you'll get from Gravity as well, just rebranded. Multiple brands exist for this one product.This meter is just not accurate after testing on both the raspberry pi and arduino mega. Even with calibration the meter is off by huge margins (over 50%) at 0 - 2000 ppm range. It seems the higher the salienity of the solution being measured the less accurate.After preparing multiple test solutions of 0 ppm, 100 ppm, 500 ppm, and 1000 ppm using distilled water and pouring hours of time into trying to get this thing to produce any semi-accurate readings I have to conclude this thing is just junk.Either I got a bad one or it just doesn't work. No information as to exactly how the device works either, confusing specs like 5v input but only 0 - 2.3v output? How does an ADC interpret this then if the output range is lower than the vref range?? No explanation, no datasheet, no documents, only a shotty wiki entry online that has some poorly written and misspelled code on it.

WikiPage Pi example not working
The product build quality seems great. I was able to get it connected with an ADC to my Raspberry Pi a few minutes. However, the configuration instructions aren't very clear on their Wiki page. I noticed the wiki page for other CQRobot products had a zipped file containing the test code but this one didn't. I've spent a few hours trying to get the resolve.
