CO2 Sensor

image 12.jpg

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) at a predetermined Heartbeat Interval (HBI) via the SecureDataShot™ protocol. Cloud Connectors relay sensor data to the cloud via cellular or ethernet connectivity. From the cloud, the data can be integrated into other services using REST APIs and webhooks or viewed directly in DT Studio.

The Wireless CO2 Sensor uses HBI to transmit a message notifying the system that it is present and operational, which can be set to 2.5 min, 5 min, 15 min, 30 min, 45 min, or 60 min. 

This sensor comes in two versions: EU (Product No. 102521) and US (Product No. 102522), each tailored to meet distinct regional certifications, compliances, and wireless communication requirements.
