You are tasked to design a micro system that receives sensor data from multiple sensors and stores it on board. Once a user connects an external system (such as a laptop or desktop) to this system, you should allow the data stored on the micro system to transfer to the external system.

A complete answer will address each of the problems below:

The bus type used to connect the sensor to the system

How the micro system detects a connection to the sensor

How data transfer from the sensor to the micro system is initiated OR how the system will detect that new data is available on the sensor

How the micro system handles the data internally

How the micro system initiates storage within the system

How the micro system retrieves data from memory

How the micro system transfers data to an external system

Describe the types of connections you would apply to the system and the path the data will take.

Also describe if and when you think interrupts should be used (HINT: Think about what happens when you want to download data from the micro system).

See the diagram below for an outline of the micro system:
