How To Use MQ-135 Gas Sensor - Codrey Electronics

2020-07-05· In this sensitivity characteristic curve (borrowed from the datasheet), Ro is the sensor resistance at 100ppm of NH3 in clean air, and Rs is the sensor resistance at various concentrations of gases. If you want to do anything serious with MQ-135 gas sensor, then you should learn to analyze this plot pretty well. However that needs some skill ...

Ammonia Sensor. - Sensors - Arduino Forum

2021-05-06· The ammonia gas sensor you looked at will meaure ammonia in air, and it is less sensitive than your nose is. Yes, That is my ideas, I want to determind the total concentration of ammonia in aquarium water. It consists of NH3 and NH4+. As I know, to determind the concentration of NH3, we have to measure the pH and total concentration of ammonia.

Interfacing MQ137 Sensor with Arduino to Measure Ammonia ...

2018-02-09· 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 (X-axis) we can use this graph to find the value of ppm (Y-axis). To find …
