The Cloud solution proposed to guarantee data integrity and its accessibility and to create a network of measurement nodes that periodically transmit the information to a local acquisition unit.

The control unit provides time stamping and archiving of the acquired data, making them available via Wi-Fi.
The control unit can operate independently without an internet connection.

Each controller is equipped with a radio module so it can connect to the unit  IoT Gateway and send the acquired data relating to the detected parameters, according to the following scheme.

The network operates in the Industrial Scientific Medical band (ISMB) according to IEEE 802.15.4 specifications

This type of configuration guarantees high reliability of data transmission.
