Ammonia Sensor for ClosedLoop SCR Control

SENSOR NH3 EMF [mV] 042406B2 EMF. Figure 3. Wateroxygen emf difference as function of air humidity and A/F Increasing air humidity has two effects on the ammonia sensing emf. It lowers emf and changes the shape of A/Fdependence. In the range of A/F ratio between 20 and 50 the maximum emf variation observed is 15 mV at 0 g/kg, 5 mV at 20 g/kg and 9 mV at 60 g/kg. For comparison, a 15 mV ...

How To Use MQ135 Gas Sensor Codrey Electronics

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..

Interfacing MQ137 Sensor with Arduino to Measure Ammonia ...

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 ...
