The Efento NB-IoT wireless carbon dioxide (CO₂) logger measures gas concentration and transmits the values via a mobile network (Narrowband IoT).
An NB-IoT SIM card and an active cloud license are required for operation.
In addition to CO₂, the logger also measures temperature, humidity, and barometric pressure. The sensors are equipped with a Bluetooth Low Energy interface, allowing fast and easy configuration via smartphone. Efento NB-IoT CO₂ sensors can be integrated with Efento Cloud or any compatible cloud platform.
