MQ135 Arduino library | Details |

01/01/2015· The datasheet claims that the MQ135 is sensitive for CO2, Alkohol, Benzene, NOx, NH3 and the Fig 3 shows the change in resistance depending on the concentration of these gases in the ambient air in ppm (of the total gas volume). It turns out the the general sensitivity is the roughly same for all the gases. This is where you think: Wait a minute! CO2 is the 4th most abundant trace gas in the ...


MQ135 Sensor calibrate and configure DIY Projects

06/05/2020· 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 …

MQ135 CO2 PPM Calculation Firmware Particle

01/07/2016· I am working on MQ135 Gas sensor for CO2 PPM. I refer Internet blogs, datasheet, internet codes and i apply in my coding. I also got result in PPM in range of 420 to 450. is it true or not? What is CO2 PPM in Air? Also it gives me reading in loop, it can not go beyond 450 PPM. I used this equation Rs=( ( * RL ) ( RL * Vout ) ) / Vout, where Vout is ADC value RL=10 ratio=Rs/R0, …
