Sensor Recommendations Please

Has anyone used and can recommend sensors to measure:
-ammonia level
-nitrate level
-nitrite level
thank you,

Sensors? You mean like something for an Arduino project?

Most people use chemical tests, such as those from API.

If speaking of mechanical electrical sensors, I would not bother. Ammonia and nitrite at any level is not expected or acceptable so I only measure them when I suspect trouble. For nitrate, I only need to know if it is more, less or the same. That leaves me using the 5-in-1 strip that shows best to my eyes. It takes a bit of trial and error to find which works best for you but I like the Jungle brand as cheap easy and available since the test is not a place where great precision is needed.

did not hear about such sensors used in the DYI projects. They are way too expensive.
Strips or liquid tests will do the job, as @PlantedRich already mentioned. Usually, you use Amonia and Nitrite only after you setup the tank, and once that is balanced, things are ok, and your test is sitting unused.
Nitrate is the only one that a planted tank has to keep an eye on, especially if there is a fertilization going on. But again, once you know your regime of fertilization, you pretty much know what are the levels, and check them from time to time, and yes, you need just the ballpark of the measurements.

So, I would not bother with spending money on that unless is as cheap as a Ph probe (and I do not use even that one in my Arduino iAqua built)
