Abstract: The disclosure relates to a system on Chip (SoC) for an Internet of Things (IoT) device. An example use case is a faucet system with a SoC unit. Automatic faucets include different components such as a solenoid valve, sensor and control electronics, power source, and faucet. Automatic faucets turn on in response to different trigger events. The IoT unit can track activity by the faucet, for example. Another example use case in an electrical outlet system with a SoC unit.
