About this Gig

Need a reliable smart energy meter prototype to validate your idea before mass production? I will design and build a proof-of-concept embedded IoT energy meter that measures power/energy accurately and sends data to the cloud for real-time monitoring and basic billing logic.


What you'll get


  • Embedded firmware development (ESP32/STM32/Arduino-class MCU)
  • Energy measurement integration (voltage/current sensing + calibration approach)
  • Real-time readings: V, I, P, kWh, power factor (as supported by your sensor/IC)
  • Wi-Fi IoT connectivity: MQTT/HTTP to your server or platforms like Firebase/ThingsBoard
  • Dashboard-ready data: live values, history logging, usage trends
  • Alerts & automation: threshold notifications, overload/peak usage triggers
  • Prototype documentation: wiring, firmware setup, test steps, and handover notes


Real-world impact


  • Reduce electricity waste by identifying high-consumption loads and peak usage
  • Enable automated billing and transparent consumption tracking for tenants/rooms/shops
  • Remote monitoring for facilities without manual meter checking
  • Fast validation for startups and businessesprove your concept before investing in tooling
