Efento NB-IoT wireless carbon dioxide (CO2) logger measures gas concentration and transmit its values over a cellular network (Narrowband IoT). On top of the gas concentration, the logger also measures temperature, humidity and barometric pressure. Sensors are also equipped with Bluetooth Low Energy interface, which allows quick and easy configuration with a smartphone. Efento NB-IoT CO2 sensors can be integrated with any cloud platform.
