    hat ein bisschen gedauert, wegen verkehrten Adressen etc aber letztlich doch beklommen.

    For beginners or arduino examples like eucation or home air analyze can use freely, but for profesional devices like medical air-clear or weathers statiin i not recomending to buy this sensor. Or use double for get more precession value. Software for testing this and ssome other sensor we gift to banggood, and you can download from this link: http://www.mkey-support.com/ip/banggood/iSersorAPP[v1.0].zip p.s. stabilisation time = 2 minuts! (after run, call procedure delay_ms(2000 * 60));

    I've bought more of these sensors by now, it's excellent. What makes this sensor excellent that it measures directly the CO2 level unlike the ones that guess it based on air quality (cheaper ones _guess_ CO2 level based on various particle levels). So if you want a good sensor go for this or other NDIR variants and don't settle for cheaper ones that don't directly measure CO2 level.

    Very fast shipping! Not tested yet, looks OK. Nagyon gyorsan ideért, még nem próbáltam, de jónak néz ki.

    An excellent CO2 sensor for a low price In conjunction with an Arduino board one can realize a fine data logger

    Works as expected! Took me some time to get it to run, but now it works quite fine. What's also worth to be mentioned in my opinion: the sensor works by the CO2 deffusing into the measurement chamber (golden part) through the white membrane on the top, so if you want measurements with a quick response, you should make sure that there is a steady stream of the measurement media going over the membrane. Link to the Arduino Library I wrote for this sensor: https://github.com/Jan-NiklasB/MH-Z14A-Library Funktioniert wie erwartet! hat ein wenig gedauert bis es reibungslos lief, aber jetzt funktionierts. Was ebenfalls noch Erwähnenswert ist, ist dass der Sensonsr funktioniert, indem das CO2 durch die weiße Membran an der Oberseite der Messkammer (goldener Teil) diffundiert. Es ist daher ratsam wenn man eine schnelle Ansprechzeit benötigt einen stetigen Strom des Messmediums über die membran laufen zu lassen. (Lüfter o.ä.) Link zur Arduino-Lib, die ich für diesen Sendor geschrieben hab: https://github.com/Jan-NiklasB/MH-Z14A-Library

    Упакован хорошо, в комплекте есть кабель. Кроме разъема ещё есть и отверстия под пайку или под пины.

    Super-fast delivery. Arrived in good condition. This is a follow-up order for the third time. The sensors have a very good value for price. In particular the auto calibration is working astonishing well. Usage in schools to display need to open windows/change air.
