IQS680

The IQS680 ProxFusion® IC is a multifunctional Capacitance, Passive Infrared Radial (PIR) & Inductance sensor designed for applications such as domestic energy efficient lighting applications with movement detection. The IQS680 is an ultra-low power solution designed for short or long term activations through any of the sensing channels. The IQS680 operates standalone or via the I2C protocol and custom configurations are stored in an on-chip EEPROM.
