SparkFun Linear 3D Hall-Effect Sensor - TMAG5273 (Qwiic)

The SparkFun TMAG5273 Qwiic Linear 3D Hall-Effect Sensor is a low-power, high-precision magnetic field sensor that can detect a magnetic field's presence, strength, and direction in three dimensions. Ideal for magnetic proximity detection, door and window sensing, mobile rotor control, and more, this board fits perfectly into a compact 2.54cm x 2.54cm Qwiic breakout.The TMAG5273 from Texas Instruments features a configurable linear magnetic range of either ±40 mT or ±80 mT, along with TI's integrated angle calculation engine (CORDIC) for gain and offset adjustments. It includes magnetic tamper detection and configurable wake-up/threshold settings that can trigger interrupts via the I²C interface or a dedicated interrupt pin.With a power consumption of just 2.3mA in Active Mode (1µA in sleep mode), a high precision of ±0.5% typical accuracy, a Disable button, and a built-in temperature sensor, the TMAG5273 is an excellent choice for anyone needing a low-power, high-precision magnetic field sensor.Communication is handled via I²C, with pins broken out to the Qwiic system, eliminating the need for soldering. For those who prefer, the I²C pins are also available on standard 2.54mm-spaced pins.Features:Breakout Board
