Results that are calculated and displayed include incoming AC voltage, current, frequency, active power, reactive power, apparent power, power factor, and energy consumption in kWh. In addition to being a fully functional tool for energy measurement, the Energy Watchdog is a development tool to help system designers develop their own smart plug designs and go-to-market very quickly. The tool has a debug port as well as serial interfaces to connect optional peripherals, like wireless communication modules to transmit energy consumption data to a remote location. Wireless solutions such as ZigBee or sub-1 GHz solutions like wireless M-Bus are available from TI and can connect easily to the Energy Watchdog tool. Full schematics and software are available for system designers to get started with smart plug development right out of the box.
