Adafruit TLV493D Three-Axis Magnetometer – STEMMA QT/Qwiic

The TLV493D 3-Axis Magnetometer is a great little sensor for detecting magnets in 3D. In fact, the manufacturer Infineon suggests that it could be used to make a joystick! You could also use it for other cool things like detecting objects with magnets attached, like the lid of a box, or perhaps a statue that unlocks your secret hiding place when placed on your mantel? The TLD493D excels at measuring nearby magnetic fields in three dimensions. It won’t make a good compass, it’s not sensitive enough to pick up the Earth’s magnetic field, but you can use it to track the movement of nearby magnets in three dimensions. Here are a few specifications: Digital output via 2-wire based standard I2C interface up to 1 Mbps. 12-bit data resolution for each measurement direction Bx, By and Bz linear field measurement up to +130 mT Excellent adjustment of the X/Y measurement for accurate angle measurement As we are used to, we have made the TLV easy to use by combining it with Place the circuit on a breakout circuit board for support. A voltage regulator and logic level circuitry make it usable with a range of microcontrollers with either 3.3V or 5V logic levels. We even give you a pen to use the excess 3.3V juice not needed by the TLV493D. We’ve also equipped the breakout with SparkFun Qwiic compatible STEMMA QT connectors so you can use it with other similarly equipped boards without having to solder. Because the TLV493D “speaks” I2C, you only need two cables (in addition to the power supply) to connect to your microcontroller and you can share these pins with other I2C sensors. The manufacturer Infineon was kind enough to provide a library for using the sensor with Arduino, and we wrote one to use it with CircuitPython and Python for use on Raspberry Pi and other Linux computers. Dimensions: 25.4 x 17.8 x 4.6 mm. Weight: 1.8 g.
