Product description: SparkFun Mini Linear 3D Hall-Effect Sensor - Hall sensor module - Qwiic - TMAG5273 - SparkFun SEN-23881
A miniature module from SparkFun equipped with a TMAG5273 Hall sensor from Texas Instruments. It detects the presence of a magnetic field, its strength and direction in three dimensions , thanks to which it is used when it is necessary to detect magnetic proximity, it will also work when creating HID interfaces and replace mechanical switches. The configurable magnetic range is ± 40 mT (820 LSB / mT) and ± 80 mT (410 LSB / mT) . The module is powered by a voltage in the range from 1.7 V to 3.6 V , it is easy and quick to integrate thanks to the Qwiic system and communication via the I2C bus.
