Edison with sensors : This is a Edison with Arduino breakboard with a Grove breakout attached. The sensors attached to this board will be.
Light sensor
Temperature sensor
Touch sensor
Sound sensor (not sure yet how it works, this is optional)
Edison : This card will work only as a bluetooth device count sensor. This means that this board only will report how many bluetooth devices are in the range.
Edison with Arduino (2) : The Edison will connect to the Arduino 101 through bluetooth to retrieve accelerometer and gyroscope metrics.
The other components left are:
Database : A Postgresql database somewhere else in the network. This database can be replaced with Intel's cloud service, but we need to check that.
Lets consider in the decision :
To have a better estimation.
