Energy Monitoring in Real Time with IoT
An improved IoT-based smart energy monitoring device that measures both voltage and current in real time to accurately calculate power usage, energy consumption, and billing.

The Energy Monitoring in Real Time with IoT project functions by combining voltage and current sensing hardware with the IndusBoard Coin microcontroller to continuously measure electrical parameters on an AC power line. To capture voltage safely, the system uses the ZMPT101B AC voltage sensor module, which steps down high-voltage mains alternating current to a safe, micro-controller-compatible low-voltage analog signal. Simultaneously, a current sensor measures the electrical current flowing through the circuit. Both of these analog sensor outputs are wired to the IndusBoard Coin, where its analog-to-digital converter samples the waveforms in real time. Using the Arduino IDE, the microcontroller executes custom calibration code to convert these raw digital readings into accurate root-mean-square (RMS) voltage and current values. By multiplying these synchronized measurements together, the system calculates instantaneous power usage and accumulates energy consumption over time. Finally, the IndusBoard Coin utilizes its onboard IoT capabilities to transmit this processed billing and power telemetry data to an external IoT dashboard software or database, allowing users to visualize energy usage trends remotely through the serial plotter code and web interfaces.

Frequently Asked Questions
You will need the Arduino IDE to write, calibrate, and upload the monitoring code to the IndusBoard Coin, along with a compatible IoT dashboard software or database to visualize your data.
The ZMPT101B module uses an onboard miniature voltage transformer to isolate and step down high AC mains voltage into a safe, low-voltage analog signal that the IndusBoard Coin can safely measure.
Calibration code maps raw analog-to-digital converter values from the ZMPT101B and current sensor to actual calibrated units (like volts and amperes), ensuring your power and billing calculations are accurate.
