MQ137 Pinout, Interfacing with Arduino, Datasheet ...

The MQ137 is an ammonia gas sensor which detects the presence of ammonia gas. As the concentration of N gas rises in the air, the conductivity of the sensor tends to become higher. Using a circuit, you can convert this change in conductivity to the output value which indicates the concentration of a gas. Along with ammonia gas, it can detect ...

Interfacing MQ137 Sensor with Arduino to Measure Ammonia ...

Feb 09, 2018· 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 ...
