Interfacing MQ137 Sensor with Arduino to Measure Ammonia ...

20180209· The best value for RL will be 47K as suggested by datasheet hence we are going to use the same. ... 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 …

Bump Testing Ammonia (NH3) Sensors Critical Environment

20180228· Bump Testing Ammonia (NH3) Sensors 28 February 2018 Bump testing a gas sensor involves flowing a concentration of gas that is slightly higher than the Low alarm setpoint of the gas detector for a short period of time (12 minutes or less). The purpose of a bump test is to confirm that the sensor responds to the presence of gas, the low alarm will activate and the gas detector overall is ...
