Linear Hall effect sensor based tachometer

Magnetic Tachometer

Project Goal

The project focuses on the development of a magnetic tachometer from the linear Hall-effect sensor 811JF-55A4.

To achieve this aim, the sensor was used in combination with the following hardware:

• Arduino Micro;
• Powerbank Solar charger 5.5V output, 300-600mA;
• Booster DC-DC Step-up 2/24V to 5/12/28V Micro USB;
• ON/OFF switch;
• LM358AN OpAmp;
• CA9-MT-V10-10K Potentiometer;
• HC-05 Bluetooth module;
• Neodymium Magnet (N35);

Files

Folders are organized as follows:

• Arduino Code hosts the .ino file containing the algorithm for RPM measurements;
• Calibration hosts the MATLAB code used to display the measures performed to characterize the sensor;
• Case Design contains the .SLDPRT files for the 3D printed case;
• Circuit hosts the circuit diagrams made using Fritzing software;
• Processing Code contains the GUI interface made via Processing, implementable both on Laptop and on Android smartphone.
