IQS622 Eval Kit 4

The IQS622 ProxFusion® IC is a multifunctional ambient light sensing (ALS), active IR, capacitance & Hall-effect sensor designed for applications where any or all of the technologies may be required. The IQS622 is an ultra-low power solution designed for short or long term activations through any of the sensing channels. The IQS622 is fully I2C compatible and can be configured to operate on an event mode basis to wake-up on dedicated sensors.
