Gas sensors have been designed for use in industrial plants, production halls or in urban spaces. Thanks to the gas logger, it is possible to remotely read the gas concentration in a given room or in a specific space. In addition to measuring the gas concentration in the air, the sensor measures temperature and humidity. Efento’s wireless air quality loggers are based on Bluetooth Low Energy, NB-IoT and LTE-M technologies. Sensors can be used with Efento Cloud or any other IoT platform.
