The AG973-07 Evaluation Kit has everything you need to test and evaluate
the easy-to-use SM223-10E I2C Smart Magnetometer. The kit includes:
A 1" x 1.6" (25 mm x 41 mm) evaluation board with:
- an SM228-10E sensor.
- a microcontroller connected to the sensor via I2C.
- a current-carrying trace under the sensor for evaluating as a current sensor.
An LED indicating the state of the threshold output.
A PWM board output for an analog representation of the measured magnetic field.
A simple, intuitive graphical user interface.
Simple software installation.
USB cable to connect the Evaluation Board to a computer.
A small ceramic magnet for evaluating as a proximity sensor.
The AG975-07E provides easy connections to an SM223-10E high-sensitivity Smart Magnetometer. In addition to the sensor, the board has a recommended bypass capacitor and a six-pin header connected to each of the sensor I/O pads.
The board is approximately 0.6 by 0.75 inches (15 x 19 mm).
This 2” x 2” square evaluation board allows you to test the remarkable
ACT001-10E current sensor and a common application circuit.
The ACT001-10E is a fully-isolated, inline current sensor with
an on-chip current strap. A Wheatstone bridge manufactured
with NVE’s state-of-the-art tunneling magnetoresistance (TMR)
sensor elements detects the magnetic field from the input current
across NVE’s unique polymer isolation barrier.
A preassembled circuit board with a high-sensitivity AAH002-02E sensor and a differential amplifier circuit with a gain of 25. The board can be powered by a 2.7 to 12 V supply and provides a single-ended output with a typical sensitivity of 3.75 V/V/mT (375 mV/V/Oe).The circuit board is 12.5 x 7.8 mm, with Vcc, GND, and OUT plated-through holes for wires or a header.
The SM223-10E Smart Magnetometer combines a Tunneling Magnetoresistance (TMR) sensor element with
sophisticated digital signal processing for a unique combination of speed and precision. An I2C interface provides data as well as an external programming interface, and allows setting a versatile digital threshold output.
Unlike awkward, old-fashioned Hall-effect sensors, TMR is sensitive in-plane for
optimal current sensing and easy mechanical interfaces. Key features include:
0 to 1.5 mT linear range
