Design a micro system (based on the example of a micro system below) that receives sensor data from multiple sensors and stores it on board. When an external system (such as a laptop or desktop) is attached to the micro system, the design should allow the data stored on the micro system to transfer to the external system.

Address all of the items below with the microsystem that you design:

• 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:
