Smart GMR Magnetometer
The new SM124-10E Smart Magnetometer combines a Giant Magnetoresistance (GMR) sensor element with sophisticated digital signal processing.

An I²C interface provides data as well as an external programming interface. A digital output provides precise, programmable thresholds:

SM124 Detailed Block Diagram

Unlike awkward, old-fashioned Hall-effect sensors, GMR is sensitive in-plane for optimal current sensing and easy mechanical interfaces.

Key SM124-10E features include:
  • Factory calibrated
  • Can detect magnets more than 50 mm away
  • I²C and digital threshold outputs
  • 7-bit output resolution
  • In-plane sensitivity—more usable than Hall effect sensors
  • Factory calibrated
  • Internal temperature compensation
  • Programmable offset and gain compensation
  • Optional magnet temperature compensation
  • 2.2 to 3.6V supply
  • Ultraminiature 2.5 x 2.5 x 0.8 mm TDFN package

Evaluation Kit
The AG952-07 Evaluation Kit has everything you need to calibrate, test, and evaluate the remarkable SM124-10E Smart Magnetometer:
AG952-07 Evaluation Kit
The evaluation kit includes:
  •  An evaluation board with:
      -  an SM124-10E 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.

Here’s a live demonstration of the kit:

Self-Contained SM124 Programmer 
The new SM124 Smart GMR AG955-07 Programmer ModuleMagnetometer can be programmed for whatever magnetic threshold you want, and a ridiculously simple I≤C interface lets you program it from a microcontroller.

And we also offer a self-contained board that lets you set the threshold with thumbwheel switches. No computer needed.

There is a pushbutton for rezeroing, and miniature thumbwheel switches for programming threshold and hysteresis. The module is powered by a small wall-mounted power supply (included).

Jumpers allow the SM124-10E to be disconnected from the rest of the board so the board can also be used as an interface to the customerís electronics.

Smart Magnetometer Socket Board 
The AG954-07E provides a socket for easy programming and prototyping of TDFN6 devices without soldering and unsoldering.

The custom socket is compatible with NVE's 2.5 mm x 2.5 mm TDFN6 package parts (-10E suffixes), including the new SM124-10E Smart Magnetometer:

The AG954-07E Socket Board

A 0.1"-spaced header provides for connections to the sensors, and a row of 0.1"-spaced through-holes allows for auxiliary parts such as a decoupling capacitor or an LED for the Digital Output pin.

The board is 1.5" x 2" (38 mm x 50 mm), and uses brass hardware to minimize magnetic interference with the socketed sensor.
