Smart Plug with Remote Disconnect and Wi-Fi Connectivity


Design files


This design implements single-outlet energy measurement with remote connect/disconnect capability and Wi-Fi connectivity. Designers can quickly create networked load control devices for industrial building and home automation applications.

  • SimpleLink™ Wi-Fi connectivity over IEEE-802.11 b/g/n networks from any smart phone, tablet, or computer through a standard web browser
  • Single-phase energy measurement that calculates RMS current, RMS voltage, active and reactive power and energies, power factor, and frequency
  • Solid-state relay provides remote connect/disconnect capability
  • Compact physical design with minimal BOM components
  • Low-power components plus efficient power supply provide low system power consumption
  • The system design is tested and includes firmware for energy measurement, Wi-Fi connectivity, and relay control along with Android-based demo application and user’s guide
  • Enables the Internet of Things (IoT)
