Hall effect wheel speed sensor arduino. Useful links and tutorials on hall effect sensor. The gnd of the sensor is connected to the gnd pin on the arduino. Simply speaking a hall effect sensor or ic detects motion position or change in magnetic field strength of either a permanent magnet an electromagnet or any. With a lab scope a 2 wire hall effect abs sensor signal voltage is measured with the wheel turned by hand.
Achim and shutterdrone s suggestion to use a reed switch makes more sense though given the supporting hardware a hall effect sensor requires to get a clean digital signal. If you remember the arduino waterflow sensor tutorial we implemented earlier the main component of the water flow sensor is the hall effect ic. In continuation with my previous instructable rc car that you can find on this linkrc car using infraredi ve decided to upgrade the car with rpm measurement using hall sensor and a neodymium magnet.
