AEV Data ConversionAEV User Manual – System Analysis 1

The data recorded with the Arduino is in the form of integers that must be converted to physical parameters

Available data from Arduino includes: EEProm Time (TE) Current (IE) Voltage (VE)

First-Year Engineering Program

AEV Data Conversion cont.AEV User Manual – System Analysis 1

Convert into the physical parameters of Time (seconds) Current (amps) Voltage (volts)

Analyze the data by calculating: Power (watts) Incremental Energy (joules) Total Energy (joules)

AEV Data Conversion cont.AEV User Manual – System Analysis 1

A rectangular approximation of the power and time will be used to calculate incremental and total energy

There are 3 approximation methods:

AEV Data Conversion cont.AEV User Manual – System Analysis 1

The midpoint method will be used by averaging the power of 2 neighboring points and multiplying by the time increment

Sum up the incremental energy for the total value used throughout the operation
