Hall Effect Bicycle Speedometer

Project Overview

Designed and fabricated a universal bicycle speedometer with the use of rapid prototyping, National Instruments (NI) myDAQ, LabVIEW, and a hall effect sensor. Successfully demonstrated the measurement of RPM, velocity, and total distance traveled using LabVIEW's front panel.

What?

  • Created a bicycle speedometer with an A3144 hall effect sensor.

  • Utilized LabVIEW front panel to display bicycle wheel RPM, velocity, and total distance traveled.

  • Worked with a team of 3 to integrate all components of the project.

How?

  • Acquired and displayed data through National Instruments (NI) myDAQ and LabVIEW.

  • Designed universal mount through SolidWorks.

  • Fabricated (PETG) using rapid prototyping (FDM 3D printing).

Results

  • Successfully developed a speedometer to display bicycle speeds on LabVIEW's front panel.

  • Achieved universal fitment by accommodating for any wheel size and making use of adaptable mounting design.

SJSU: ME 120 (Experimental Methods) - Term Project

This Hall Effect Bicycle Speedometer was my term project submission for my ME 120 course at SJSU. This was done within a team of 3. The semester goal for this project was to utilize our LabVIEW and myDAQ knowledge, gained through the semester, and apply it on a real world application.
