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.

In constant use for 2+ years
I've had this connected to an esp32 to monitor my fish tank. Helps give me a nice reminder if my tank is really dirty and needs a cleaning. 24/7 use for the last 2 years, no issues, and still going strong.

Seems accurate
Plugged this into my arduino uno, copied the code from cqrobot.wiki and it seems to be working great. Tap water reads 180 ppm. Purified drinking water reads 0. Was a little worried by some of the other reviews, but I'm impressed.

Does not work, have bought multiple. try another brand, these are trash
i have bougt 2 of these sensors and spent countless hours adjusting code for these to calibrate, and they are just total junk.

Not good for hydroponics, works for regular water
It only goes up to 1,000ppm. Most hydroponics are 900 to 2,000ppm. Works great for water, aquarium or pool but claiming hydroponics is a stretch.
