The 3D magnetic sensor TLV493D-A1B6 offers accurate three-dimensional sensing with extremely low power consumption in a small 6-pin package. With its magnetic field detection in x, y, and z-direction the sensor reliably measures three-dimensional, linear and rotation movements. Applications include joysticks, control elements (white goods, multifunction knops), or electric meters (anti tampering) and any other application that requires accurate angular measurements or low power consumptions. The integrated temperature sensor can furthermore be used for plausibility checks.
Key features are 3D magnetic sensing with a very low power consumption during operations. The sensor has a digital output via 2-wire based standard I2C interface up to 1 MBit/sec and 12 bit data resolution for each measurement direction (Bx, By and Bz linear field measurement up to +-130mT).

Processing
This library supports the open-source software Processing for creating GUIs. It allows you to connect your evaluation board to a PC over serial communication and visualisation of the embedded system. Find out more on the Arduino homepage here. The respective files are stored in the /processing folder of this repository.
Printables
The TLx493D 3D magnetic sensor family has additional tools which can be directly mounted on top of the evaluation boards. The 3D print data of the joystick, the rotate knob and the linear slider can be found in the folder printables.
