The main component of the master node is an Industrial board that takes care of the management of all the data communication buses. In order to increase the number of the communication bus an integrated circuit has been mounted on the board, the LAN9514 is a high-performance USB 2.0 Hi-Speed ​​hub with a 10/100 Ethernet controller, and is able to manage 4 ports USB that can be used for connecting expansion devices: such as pen drives, keyboards, mice, printers, wireless communication devices and more; while the Ethernet bus is essentially used for data communication over the network (cloud).
The LAN9514 hub also provides over 30 programmable features, including: PortMap (also referred to as port remapping) capable of providing flexible port mapping and enabling and disabling sequences; PortSwap that allows the programmability of the pins of the USB differential pair; PHYBoost which allows you to enable four different power levels on each USB port.

MICROCONTOLLER: The microcontroller is the heart of the sensor node: it acquires, controls and manages all the other subsystems and acts as an arbiter on the data bus communications. It is a high performance and low consumption device with a CPU based on RISC architecture.
DATA TRANSMISSION AND RECEPTION VIA XBEE
PROBE ACQUISITION SYSTEM: 4 probes can be connected to each sensor node. Each probe supplies an analog signal at its output which, once processed (analog buffer and switch) by the electronic board, is measured by the 12-bit analog to digital converter present in the microcontroller. The system is very flexible as it lends itself to further future applications as other probes and sensors (temperature, pressure, force, physico-chemical, etc.) can be connected which provide an analog output.

In the case of the accelerometer, at each sending the platform will not receive a single data (such as the temperature at a given time), but an array of data corresponding to a sampling of n seconds. Depending on the sampling rate, you will have more or less data.
For example, if you sample for 1 second at 6 kHz, you will have 6000 acceleration data (on each axis) for each sample.
Furthermore, from the acceleration data it is important to derive, through the Fourier Transform, the peaks of the main frequencies present. The analysis of these peaks allows the implementation of predictive diagnostics.
The HyperIoT platform was therefore equipped with a widget that allows you to view the acceleration data and an enrichment that calculates the Fourier transform and then allows you to view it in an ad hoc widget.
The sensor sends the data in JSON format as requested by the platform, with the MQTT protocol.
