Amazing Features

Unlike awkward, old-fashioned Hall-effect sensors, TMR is sensitive in-plane for optimal current sensing and easy mechanical interfaces. Key SM324-10E features include:

  • Can detect magnets more than 50 mm away
  • I2C and digital threshold outputs
  • 24-bit output resolution
  • In-plane sensitivity more usable than Hall effect sensors
  • Programmable offset and gain compensation
  • Internal temperature compensation
  • 1.68 to 3.6 volt supply
  • Ultraminiature 2.5 × 2.5 × 0.8 mm TDFN package

The kit includes:

  • An evaluation board with:
    • an SM324-10E sensor.
    • a microcontroller connected to the sensor via I2C.
    • a current-carrying trace under the sensor for evaluating as a current sensor.
  • A powerful, intuitive graphical user interface.
  • Simple software installation.
  • Flexibility to power from USB or external power supply.
  • Isolated USB interface for safety and low noise.
  • USB cable to connect the Evaluation Board to a computer.
  • A small ceramic magnet for evaluating as a proximity sensor.

SM324-10E Smart Magnetometers are priced at $1.94 each in 1000-piece quantities. The AG951-07E Smart Magnetometer Evaluation Kits are priced at $245.00 each. Sensors and kits are both in stock for immediate delivery.
