20170104· Measure CO2 with MQ135 and Arduino. I had bought 3 MQ135 gas sensors on AliExpress to test if it is possible to measure CO2 with them. First I started with a very simple analog read to check the values in my computer/hobby room with a CO2 ppm around 650.

CO2 Monitor Arduino Project Hub

+

The CO2 concentration is calculated from the measured resistance and the temperature/relative humidity correction. 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 ...

+

20211121· The SCD30 is an NDIR sensor, which is a ''true'' CO2 sensor, that will tell you the CO2 PPM (partspermillion) composition of ambient air. Unlike the SGP30, this sensor isn''t approximating it from VOC gas concentration it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...

CO2 Monitoring with K30 Sensor Arduino Project Hub

+

20170620· 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, autocalibrating 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.
