MQ135 Sensor - calibrate and configure - DIY Projects

2020-05-06· MQ135 Sensors are usable as an air quality sensor for detecting a wide range of gases, including NH3, NOx, alcohol, benzene, smoke and CO2. For me, these sensors should be affordable by the price but also deliver acceptable measurements. That’s the reason I decided to test this MQ135 Sensor. Five of them are available in our region even with amazon for 11€ which make these little …

MQ-135 Air Quality Sensor Circuit - Working and ...

2019-08-09· The arduino voltage regulator can’t deliver this much current. For testing, you can connect a ammeter in mA range at the output pin B and bring a cigar gas lighter. Try to leak the gas without igniting it near the sensor. As the concentration of gas rises around the sensor, the current flow through ammeter increases. If this works, your sensor is working normally. Now, you know quite a bit ...

MQ135 NH3 RIGHT VALUE OF PPM - Arduino Forum

2021-05-05· The file shows, on the first page, how the sensor needs to be connected to the Arduino. At a minimum, VRL and GND needed to be connected to the Arduino, AND a suitable value for RL needs to be selected. You then take a reading with the sensor in 100PPM Ammonia. That gives you a value, Ro.

Measure CO2 with MQ-135 and Arduino Uno - Rob's blog

2017-01-04· The next morning ppm was down to 500 according to the NETATMO, but the arduino showed a ppm of 600. I change the RZERO to 819 and the arduino also showed 500. This is no good of course, so something must go wrong in the calculations in the MQ135 library. Or I am using a MQ-135 sensor with a bad response curve.
