How does Arduino measure energy consumption?

In order to measure energy consumption, you need to use a shunt. A shunt is a resistor which you put in your electronical circuit: when current go through the little value resistor, a differential voltage is created. Energy can be calculated with the Ohm law : Power = Voltage x Current.

What is Arduino energy meter?

So this meter measures the supply current to your home through a CT (current transformer) and then does a couple of calculations to give you your current, power, maximum power and kilowatt hours consumed. Its also really easy to add your local tariff and display the cost of electricity used to date.

How Arduino read data from energy meter?

This meter is equipped with an optical infrared interface and a RS485 interface to distribute the collected data via the so called SML protocol. In this project we will use the RS485 interface to connect an Arduino to the meter and read out the values for total power consumption and real power.

How do you make a power meter?

DIY POWER METER INSTRUCTIONS

1. Drill a small hole in the spindle.
2. Glue strain gauges onto the spindle.
3. Wire up the strain gauges and feed wires through the small hole.
4. Connect the electronic module (SG53) and battery.
5. Do preliminary calibration and adjust gain setting resistor if needed.

How much power does Arduino Uno draw?

The Arduino Uno board draws about 42 mA assuming no power draw from sensors or other components needed in your system. With a minimum supply voltage of 7 volts, the power consumption of the board is therefore 0.29 Watts.

Can Arduino read RS485?

To use RS485 in your Arduino, you will require a module known as 5C MAX485TTL to RS485. This module is designed to allow serial communication over an extended distance of approximately 1200 meters; furthermore, it is bi-directional. It features a data transfer speed of 2.5 Mbps when used in a half-duplex mode.

Can Arduino detect voltage?

Arduino analog inputs can be used to measure DC voltage between 0 and 5V (on 5V Arduinos such as the Arduino Uno when using the standard 5V analog reference voltage). Code in the Arduino sketch is then used to calculate the actual voltage being measured. This allows voltages greater than 5V to be measured.

How can I monitor my Arduino energy meter?

Then I decided to monitor the voltage, current, power & energy involved in the system.

Which is the best Arduino shield for energy monitoring?

EmonTx Arduino Shield: Our open-hardware energy monitoring Arduino compatible shield featuring the above circuit alongside voltage measurement for real power calculation. 3. Interfacing with an Arduino

What makes up a monitor on an Arduino?

The monitor consists of the current sensor (which produces a signal proportional to the mains current) and the sensor electronics that convert the signal into a form the Arduino can use. For a circuit diagram and detailed discussion of sensors and electronics see: Assemble the components per the diagram above.

Which is the GSM based smart energy meter?

After the electronic ones, the Automatic Meter Reading (AMR). This system is wireless and consumption of energy meter. The reading meter will be saved to the database and bill will be generated. The latest Communication (GSM) based system. This system replace the Se rvice (SMS) to the customer and the energy board [1]. (TNB).
