Wireless Carbon Dioxide Transmitters

Our pick

GARNI 102Q

Find it on Amazon

The GARNI 102Q measures carbon dioxide from 400 to 5000 ppm and shows readings on its own display; check the exact receiver list before adding it to a weather-station system.¹²

Why this one

Choose the GARNI 102Q for indoor carbon dioxide readings with a listed compatible GARNI weather station or GTway Plus gateway; the receiver supports only one of these sensors despite its four channel choices.¹²
