Arduino-Based Smart Power Meter

One of the most practical Arduino projects for monitoring home energy usage is a smart power meter. This device allows you to track your home's electricity consumption in real-time, helping you identify energy-hungry appliances and optimize your usage.

To build an Arduino-based smart power meter, you'll need an Arduino board, a current sensor (like the ACS712), and a voltage sensor. Connect these components to your home's main power line, ensuring proper safety measures are in place.

Program your Arduino to read the current and voltage values, then calculate power consumption using the formula P = V * I.

You can display the readings on an LCD screen or send the data to a computer or smartphone via Wi-Fi or Bluetooth. This enables you to monitor your energy usage remotely and create detailed consumption reports.

Consider adding features like power factor measurement or individual circuit monitoring for more thorough insights.

Whole-House Energy Monitor

You'll need specific components and a carefully designed circuit setup to create a whole-house energy monitor with Arduino.

Once you've assembled the hardware, you'll program the Arduino to collect and process the energy consumption data.

To make sense of the collected information, you can explore various data visualization options, allowing you to track and analyze your home's energy usage effectively.

Components and Circuit Setup

To build a whole-house energy monitor using Arduino, you'll need several key components and a well-planned circuit setup. Start with an Arduino board, preferably an Arduino Uno or Mega, as the main controller.

You'll also need a current transformer (CT) sensor to measure the electrical current flowing through your main power lines. Choose a CT sensor with a rating appropriate for your home's typical energy consumption.

For voltage measurement, you'll require a step-down transformer to reduce the mains voltage to a safe level for the Arduino. Add a voltage divider circuit to further reduce the voltage to the Arduino's input range. Include an analog-to-digital converter (ADC) chip if you need higher precision readings.

Set up your circuit by connecting the CT sensor to an analog input pin on the Arduino through a burden resistor. Connect the step-down transformer and voltage divider to another analog input.

Use a real-time clock module to timestamp your readings accurately. Add an SD card module or Ethernet shield for data logging and remote monitoring.

Verify all connections are secure and properly insulated to maintain safety when working with high-voltage systems.

Programming the Arduino

Programming the Arduino for a whole-house energy monitor involves several key steps to guarantee accurate data collection and processing. You'll need to write code that reads voltage and current values from the sensors, calculates power consumption, and sends the data to a display or storage device.

Start by including the necessary libraries for your sensors and display. Define variables for voltage, current, and power. In the setup() function, initialize serial communication and configure pin modes. The loop() function will contain the main monitoring logic.

Here's a breakdown of key programming elements:

Function	Purpose	Example Code
readVoltage()	Reads voltage sensor	float v = analogRead(A0) * calibrationFactor;
readCurrent()	Reads current sensor	float i = emon.calcIrms(1480);
calculatePower()	Computes power	float p = v * i;
displayData()	Shows readings	lcd.print("Power: " + String(p) + " W");
sendData()	Transmits to storage	Serial.println(p);

Remember to calibrate your sensors for accuracy. Implement error handling and data filtering to eliminate noise. You can add features like energy cost calculation or power factor correction for more advanced monitoring. Test your code thoroughly before deploying the monitor in your home.
