I am looking for a reliable and easy to use CO2 sensors, there are too many choices on the internet i don't really know which model I should choose. Some mention they could occur "drift effect in long run", and some models require humidity calibration.

The operation environment is likely to be high humidity, and is within 10 ~ 30 C in temperature. The maximum concentration is < 2000ppm. It will be also operating 24 hours a day all year round.

Thank you in advance.
