Human Electric Trike Thesis

Design of an electrically assisted human powered trike

Data acquisition system

In order to evaluate the performance of the completed trike I plan on putting together some instrumantation to measure it’s performance. Variables I would like to log are the following:




Motor Amps

From these I can compare the actual performance to the predicted performance calculations I have made. To recored the data Dr. K.J pointed me to this $109 USB DA board:


This will plug into a laptop and allow recording of up to 8 analog inputs – currently I will need only three:

speed – optical sensor

grade – inclinometer

amps – measure voltage with shunt

The time can be tracked within the DA module, it is possible I could use additional inputs for TC’s or strain gages.

Here are some links to different inclinometers:
