The sensor uses the Hall effect to make the resulting voltage measurable or to react to a magnetic field. MMT has applied for two patents regarding first a basic structure of this torque sensor and then an optimized design [2] [3]. Using this technique, the hall sensor will be able to detect the presence of magnet around it. The north pole of a magnet is attached to the back surface if the integrated circuit is to sense the absence of ferrous matrial. Enough of theory let’s get into hardware. Throttle Position Sensor in Hall Effect Technology Hollow and D-Shaft Versions DESIGN SUPPORT TOOLS FEATURES • Accurate linearity down to: ± 0.5 % • Easy mounting principle • Non contacting technology: Hall effect • Model dedicated to all applic ations in harsh environments • … HALL-EFFECT SWITCHES FOR HIGH-TEMP. effect). As you can see, the hall effect sensor arduino circuit diagram is pretty simple. Fig. A Hall Effect sensor is a transducer that outputs a voltage in response to the magnetic field generated by the current flow. When this charged conductor comes in contact with the magnetic field which is in a perpendicular direction to the motion of electrons, the electrons get deflected. 49E Hall-Effect Linear Position Sensor. Modern Hall-effect sensor ICs integrate signal conditioning and amplification techniques to make practical devices. Another possibility is to change the reluctance of the magnet so neither the magnet nor hall effect sensor have to move. Velocity detecting of motor bicycle .
