Abstraction and Modeling

System Model

The monitoring system can be described by the following system flow chart:

Process Model

The monitoring system can be described by the following process:

1. The temperature sensor checks for temperature variations

2. Data is reported to bus

3. Data is compared against temperature threshold values

4. If CPU temperature is within range, it will check the performance of the CPU and compare the RPM of the fan with the RPM at a previous point in time

   1. Validates results

   2. Re-checks sensor readings

5. If the CPU temperature is not within range, then it will adjust the fan RPM and dissipate heat to the sink

   1. Re-checks sensor readings
