Electrical – How to measure RPM from vehicle tires? Wheel Speed Sensor

arduinohall-effectinfraredraspberry pisensor

I'm looking for a Wheel Speed Sensor to use it with a Raspberry Pi project to measure RPMs from a vehicle tires, however, I can only found sensor devices that I can't use with vehicle tires, they are for smaller purposes.

There are several ways to do it:

  • Hall Effect
  • Reed Switch
  • IR Sensor

I've found some sensors from companies but they are builded for specific devices from them.

I hope to receive some help from you guys! Thanks

This technology already exists for ABS brake sensors. Rings on the axle have spaced magnets combined with a simple 12vdc sensor. Check this out.
