MQ-135 NH3 Amonia Benzene Alcohol Gas Sensor ADC121C 12 ...

The MQ-135 Gas sensor makes it easy to monitor ammonia, benzene, or alcohol air concentration levels using our I2C Mini Module form factor. The MQ135 is connected to an ADC121C 12-Bit Analog to Digital converter, which is capable expanding to 9 gas sensors per I2C port using just two address jumpers (making full use of the floating address system).

good use of MICS-6814 sensor (gaz) ? - MicroPython Forum

22/07/2020· If it's allright you should have 0 in usual situation and nearly 30 ppm when you smoke on the sensor. I haven't calibrate NO2 and NH3 gas with a proffessional sensor like for co gas, but for moment there isn't big problem in comparaison with values of the I2c 3 gas sensor by groove on arduino (wich, for me, is wrong of 30 ppm for co gas in normal condition with 0 ppm).

Interfacing MQ137 Sensor with Arduino to Measure Ammonia ...

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

Ammonia Click | Mikroe

Ammonia Click is an Ammonia detection (NH3) sensor, based on the MQ-137 gas sensor. This gas sensor has a sensitive layer made of SnO2, which changes its resistance when exposed to ammonia. The sensor is able to sense NH3 concentration in the range of 5 ppm to 200 ppm. This Click board™ is also equipped with a trimmer potentiometer, used to adjust the sensitivity and offset of the MQ-137 ...
