    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));

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

    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.

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

    Great device! I haven't been able to test it's accuracy, but it reads about 390 ppm, and the value increases when I exhale on it and put it near a source of combustion.
