CO2 Monitoring with K30 Sensor - Arduino Project Hub

I tried a number of analog CO2 sensors for that project, but I ran into calibration issues - until I got a K30 CO2 module. This is a NDIR, digital, auto-calibrating sensor, so it's pretty easy to use. I am now starting a new open source project, this time using Arduino. I uploaded a I2C library for this sensor on Github: K30_CO2_I2C_Arduino.

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 …

CO2 Monitor - Arduino Project Hub

It may be written as: CO2 = 410*ppm* (Rs/f_RH_T / Rs410/f_RH_T_410)^b Where the exponent b is equal to - according to Mad Frog. And where Rs410 is the sensor resistance measured in clean air (410 ppm of CO2) and f_RH_T_410 is the correction factor at the moment that the clean air sensor resistance is measured.
