Notes

We're going to take care of the image recognition part to recognize customers and estimate sex, age etc... locally, for the following reasons:

Images of people are not going to the cloud => better privacy
The bridge is already taking care of processing the raw data, so that only clean and ready to use data are sent to the cloud
We are selling more expensive hardware to the customers instead of paying higher amounts of money on the server subscription
normal Webcam

Finding a good library for people recognition
Do we have a camera? (check rasperry camera)
What datas we need to actually extract from the image recognition
should the camera be in the same device as the bridge
do we need to have two different code files for the bridge and the microcontroller?
can an Arduino recognize images? or how do we make the microcontroller recognize the images (having two seperate programms run on the microcontroller part?)
Check how to save the datas to the DB (group data by message from bridge to cloud => message_id)
Web interface
bridge should tell the arduino "start I am listening"

[FF] [Flags] [Sensor ID] [Data size] [Data] [FE]

Flags explanation:
- the first bit (from the right) represents the initialization flag, which tells to the bridge if this is the first time we are sending a message about this sensor or not. If it's set to zero, the [Data] field will contain the datatype of a new sensor used and not the actual data. After sending the first message, it waits for the bridge to reply assigning an ID to that sensor. If the first flag is set to one instead, the data sent are just the actual values read from the sensors.
in the bridge there should be some kind of dictionary that converts the Sensor ID to the actual sensor to understand what data we get

{
  "bridge_id" : number,
  "Data type" : string,
  "Value" : [number, ],
}

the AI in the cloud should somehow get feedback on whether or not the decision that it took in the past was good or not
