The kit includes a circuit board with an AAT003-10E 40 kilohm Angle Sensor and a unity-gain buffer amplifier. The circuit board can be powered with a 1.7 V to 5.5 V power supply. An angular reticle on the circuit board aids in characterizing output versus angle.
The kit also includes a split-pole magnet and a plastic magnet locating fixture.
The AAT003-10E Angle Sensor's 20 kilohm output impedance is ideal for direct interface to microcontrollers.
