Efento Cloud is a complete system for monitoring temperature and humidity. The system consists of Efento sensors, Efento Gateway that receives and retransmits the measurements from the sensors, and Efento Cloud server platform. The server platform is the “brain” of the whole system, which saves the measurement data, gives users access to the data from any place in the world, decides on sending SMS / email notifications. The measurement data may come from sensors located in different cities, and the administrator of the system is able to manage the information in many ways, e.g. group some data, provide users with access to selected sensors etc.
