Ammonia, Nitrite and Nitrate Probes? Sensors Arduino Forum

· Hello, I am looking for probes for determining the amount of ammonia, nitrite, and nitrate present in a liquid. Specifically, I''m looking for something I can use to monitor (not adjust, just monitor) the chemical status of my fish tank. Googleing hasn''t found me anything but the MQ137 which is a gas sensor for ammonia, not liquid.

Interfacing MQ137 Sensor with Arduino to Measure Ammonia ...

· Turns out that MQ137 sensor can measure NH3, C2H6O and even CO. But, here I am interested only in the values of NH3. However you can use the same method to calculate ppm for any sensor you like. This graph is the only source for us to find the value of ppm and if we could somehow calculate the ration of Rs/Ro (Xaxis) we can use this graph to find the value of ppm (Yaxis). To find …
