How To Use MQ135 Gas Sensor Codrey Electronics

· Since sense resistance (Rs) value of MQ135 gas sensor is different for various kinds and various concentration of gases, sensitivity adjustment becomes very necessary. The datasheet recommends to calibrate the MQ135 sensor for 100ppm NH3 or 50ppm Alcohol concentration in air and use value of the load resistor (RL) about 20KΩ (10KΩ to 47KΩ).

MQ135 Sensor calibrate and configure DIY Projects

· 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 …

Measure CO2 with MQ135 and Arduino Uno Rob''s blog

· 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 MQ135 sensor with a bad response curve. The next day I have tested the same with another MQ135, but the results were about the same. Wrong formula in the library
