IQS624数据手册传感器变送器的多功能规格书PDF

描述 Description

The IQS624 ProxFusion® IC is a multifunctional capacitance, inductance and Hall-effect sensor designed for applications where any or all of the technologies may be required. The two 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 of the magnet without extra calculations. The inductive sensing is suitable for the detection of metallic objects while capacitive sensing provides human touch and proximity detection.
