This is a nice device, not too expensive for hobby.

For Senseair K30 CO2 sensor

The device works fine. So far I've only tested the analog output connected to Arduino A/D converter. On my request, the seller was able to disable the automatic calibration as in my application the CO2 level never reaches 405 ppm and I have to do manual calibration outdoors. I blundered and reverse connected an external +5V power supply (idiot me). Amazingly, the unit still seems to work normally.

CO2 sensor

For Arduino CO2 kit 2: sensor, LCD screen, cables

We received the CO2 within a couple of days (from Hong Kong to Belgium)
The sensor works as a charm, the data seems to be correct.
At the moment, we read the data via the arduino serial output.
The LCD screen was not yet showing data as we may have used the wrong LiquidCrystal_I2C library. But since we're not yet using the screen, we have all we want. Thanks.
A small aircraft will do measurements in the atmosphere. (as a high school science project)

Fast delivery, proper packaging, excellent communication

For Senseair K30 CO2 sensor

The delivery was fast, the seller's response was immediate and the packaging of the parcel as good as it has to be.

Works Flawlessly and arrived in 8 days

For Senseair K30 CO2 sensor

I needed a easy to use Co2 meter that wasn't expensive for testing air quality in some buildings. The K30 sensor have been a good choice. It have been very easy to interface with an Arduino, although I used the serial connection instead of the reccomended SPI interface. The sensor gives a correct reading only 4 seconds after the Powerup.

Best of the best

For Senseair K30 CO2 sensor

Very good sensor, very good price, very good seller. I won't purchase more lot this sensor on this seller if possible. Thanks.
