    5.0 out of 5 stars They work as advertised

    You have to burn or oxidize the sensor in before it will work properly. Which means powering it for about 8 hours and letting it settle for an hour before getting accurate readings from it.

    2.0 out of 5 stars not very accurate
    Reviewed in the United States on April 21, 2022
    Verified Purchase
    These are so cheap, thought I could build an alternative to an expensive air quality meter. I burned in all of them for 2 weeks, the numbers fluctuated so much and were never close to reliable, not really worth it for sensing CO2 at least, I wasn't interested in the other gas concentrations.

    4.0 out of 5 stars Worked as expected, make sure you use the right library
    Reviewed in the United States on April 14, 2022

    Never was sure if I've used it correctly because of the burn-in procedure, but there is a proper way to 'calibrate' the sensor. Make sure the calibration is done correctly or your readings will be significantly off.
    Taking off a star because of no instructions on calibration or code provided, but these can be found on Google with a bit of research.
