Azoteq IQS625 ProxFusion IC is a multifunctional capacitance and Hall-effect sensor designed for applications where any or all of the technologies may be required. The Hall-effect sensors calculate the angle of a magnet rotating parallel with the sensor. The sensor is fully I2C compatible, and on-chip calculations enable the IC to stream the current angle/interval of the magnet without extra calculations. Applications include anemometer, thermostat, dial/selector knob, mouse wheel, measuring wheel, digital angle gauge, and speedometer for a bicycle.
Hall effect angle sensor
On-chip Hall plates
Absolute Wheel Interval Output
Raw data can be used to calculate degrees on an external processor.
Wide operational range
No external components required
Partial auto calibration
Continuous auto-calibration, compensation for wear or small displacements of the sensor or magnet.
