    I’m getting 5000 readings on CO2 sensor for at least 6 hr. I checked my decoding with a COM “getdata” command – same 5000… It looks quite suspicions, but I don’t have a second CO2 sensor to check uRAD measurements. So the question is – how to diagnose CO2 or any other sensor? And if it is out of order – is there any way to reset and auto re-calibrate it?
    Thanks,

    Hi Wolfrel,
    Thank you for the response. The device eui 000000008200014E. It is conneted to a private server. You are correct 5000 is an upper boundary of the device’s CO2 sensor range. I did contact RAdu about this matter. Interestegly, the CO2 sensor crrrected itself after about 40 hr. The readings are quite in line with expected – 400-700 range. HAve you ever experianced anything like this? I

    Thnak you,
    Dmitry

    Dear Dmitry, the CO2 sensor has an auto-calibration feature that kicks in after a few hours. How is the data showing now? Thanks!

    Hello Radu,
    The sensor readings are within expected range now, but it was over 40hr before it reset.
    Thnaks,
