This sensor will show you the mysteries of magnetism. Measures upto 8 Gauss (1 Gauss is 0.0001 Tesla, and if measuring in air, it is 1 Oersted) in three orthogonal directions. Comes with one those super strong neodymium magnets. Has digital I2C outputs, for more precision. View, process and map the sensor data using our Magnetic3D software (see below). Need longer cables ? Use the ExtendCable2D-1. See this videoclip for a demo of Magnetic v2.1 !
- Measure proximity of magnetic objects (or objects with a magnet attached), or count how many pass by the sensor.
- Attach to doors and detect when they are (almost) closed.
- Measure the strength of the earth's magnetic field.
- Measure the RPM of a wheel.
Using the sensor with the Wi-microSystem enables you to use the sensor without being tethered to your computer or MIDI device.
- Any magnetic materials or fields in the vicinity of the sensor may distort the sensor output.
- Make sure the sensor is plugged into the digitizer with the red wire connected to power. Reversing the plug may cause damage to the sensor.
- 20 Aug 2014: Magnetic3D v1.20 for MacOS and Windows from source code in Max. Use together with Connect (MacOS) or BlueMIDI (Windows).

The earth's magnetic field has to be taken into account when measuring the field strength of magnets, since the strength of the earth's magnetic field at the earth's surface ranges from less than 30 microteslas (0.3 gauss) in an area including most of South America and South Africa to over 60 microteslas (0.6 gauss) around the magnetic poles in northern Canada and south of Australia, and in part of Siberia. The calibration table above includes the earth's magnetic field as measured in Montreal, Canada.
