    took a bit, due to wrong addresses etc but in the end it is depressing.

    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:[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 nice indeed! Not test again, okay. He got here really fast. I haven't tried it yet, but it looks good.

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

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

    Good sensor - data fits well to standard co2 sensors.
