The MH-Z19C is the successor to the popular MH-Z19B and is largely compatible. This version is more stable, and in practice more accurate than the MH-Z19B. This CO2 sensor can measure the amount of carbon dioxide very accurately with the non-dispersive infrared principle (NDIR).
This sensor comes with accompanying cable. We also sell a cable with a convenient DuPont connector for this sensor: Cable for Winsen MH-Z19
