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 …

Measuring CO2 with MQ135 – Pocket Science Lab

· It is marketed as a generalized “air quality” sensor, rather than precision device for measuring the concentration of any specific gas. Nevertheless, according to the data sheet the MQ135 is capable of measuring the concentrations of several gases, one of which is CO 2. This makes it an attractive low-cost alternative to more specialized (and more expensive) CO 2-specific sensors. Much …
