The Efento NB-IoT wireless CO₂ logger measures carbon dioxide concentration and also records temperature, humidity and air pressure, after which the data is sent via the NB-IoT network to Efento Cloud or another cloud platform. Thanks to the Bluetooth Low Energy interface, the sensor can easily be configured with a smartphone, and the configuration can be adjusted remotely. With a measuring range of 400–5000 ppm CO₂, an accuracy of ±(40 ppm + 5% of the reading), and up to 5 years of maintenance-free battery operation, this sensor offers reliable real-time monitoring.
