Arduino Prints AD22151 analog information to serial monitor

Printing Magnetic field sensor to serial monitor using Arduino. The AD22151 is linear magnetic field transducer. The sensor output is a voltage proportional to a magnetic field applied perpendicularly to the package top surface. The sensor combines integrated bulk Hall cell technology and instrument technology to minimize temperature related drifts associated with silicon Hall cell characteristics. Applications Of AD22151 Throttle
