The Wireless CO2 Sensor periodically measures CO2 (ppm), temperature (°C/°F), relative humidity (% RH), and barometric pressure (Pa/bar) in the surrounding air and wirelessly transmits the result to nearby Cloud Connectors (gateways) via the SecureDataShot™ protocol. Cloud Connectors relay sensor data to the DT Cloud infrastructure. From here, data can be integrated into other services using our developer APIs or viewed directly in DT Studio.
The Wireless CO2 Sensor uses Heartbeat Interval (HBI) to transmit a message notifying the system that it is present and operational, which can be set to 5 min, 15 min, 30 min, 45 min, or 60 min.
EU and US variants
This sensor is available in two variants, one for the EU and one for the US, due to different certifications, compliances, and wireless communication.
