What Do We Mean By a Home Energy Monitor, and How Does It Work?

Home energy monitors are the intelligent appliance that tracks your power consumption efficiently and effectively. It delivers the energy consumed graphically and interactively, at times displaying the number. You can sync it with the smart-home tool and even calculate solar energy production. It monitors the energy and breaks it down into kilowatts and dollars and cents. 

Why use a home energy monitor?

Presently, the cost of energy is increasing rapidly day by day. Many people are hunting ways to control and reduce their energy usage and costs. People are turning towards intelligent systems and apps that help them conserve energy. Others use energy-efficient appliances. Home energy monitors allow people to track and know about the device that consumes more power. Hence, help manage and control your energy output, reducing costs.

Are they worth it over other conventional options? 

Yes, home energy monitors are worth over conventional options. If you are always very careful about unplugging devices, an energy monitor can help give you better insight into your house’s energy consumption. Once you started tracking your power consumption, you will be forced to make energy-efficient choices.

Should you just DIY a home energy monitor

Yes, you can build a simple electricity energy monitor using hardware and software components. It can measure electrical energy and measure voltage using an AC to AC power adapter and CT sensor. The setup is relatively easy as it doesn’t require high voltage. 

The steps required to build an electrical energy monitor using Arduino are as follows:-

  1. Gather the hardware component. 

For building a home energy monitor, you will need:

  • Arduino – 1
  • Ohm resistor – 100k×1 and 470k×2
  • (for voltage divider)
  • Capacitor – 10uF × 2
  • AC Power Adapter- 9V AC
  • CT sensor × 1
  • Burden resistor – 18 Ohms
  • Breadboard – 1
  • Single-core wire – 8 to 10

2. Assemble the components on the breadboard

Connect the sensors which produce signals using two wires to the Arduino. The sensors must be promoted to primary current and voltage as the sensor electronics convert these signals into the form Arduino accepts. 

3. Upload the Arduino Sketch on the software 

The Arduino sketch is software that runs on Arduino. It converts the raw data programmed by you and outputs them into the needed serial. You can download the EmonLib from GitHub and place it into your Arduino folder. 

4. Viewing the electrical consumption

You can view the values on your computer by connecting the Arduino and should see values like absolute power, apparent power, RMS voltage, RMS current, and power factor. 

All the calculations are done on the digital domain software on an Arduino, and this electrical energy monitor can calculate actual power, apparent power, power factor, RMS voltage, RMS current.
