20200705· In principle, MQ135’s internal sensor resistor R S and external load resistor R L forms a voltage divider. In the datasheet we can see that the sensor resistor has a value of 30KΩ200KΩ (100ppm NH3). And, as pointed on the log–log plot, R S in fresh air (under certain temperature and humidity) will be a constant value..
NH3 sensor technology is available for vehicle applications. The sensor is based on a nonequilibrium electrochemical principle. It senses NH3 and outputs an emf signal that is linearly proportional to the logarithms of NH3 concentration in the engine exhaust. Testing on a diesel engine has proven that the Delphi ammonia sensors performs well in the intended

20180209· 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 the value ...
