Azoteq IQS625 ProxFusion IC
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.
