DOMESTIC SMART ENERGY METER BY USING ARDUINO Abstract

DOMESTIC SMART ENERGY METER BY USING ARDUINO Abstract Smart energy meter becomes more popular and easier to be used in industrial field. Benefits of it are: 1. Monitor energy usage data 2. Helpful to manage the power system Testing Devices • The OMICRON CMC 356 is used as a current source and a voltage source to test the sensor. The features of it are shown as below: • Powerful current & voltage sources for testing • Some of the smart energy meters are designed for domestic used • High accuracy and versatility for testing • Only provide general data and don’t provide details about which home appliances consuming the most energy. • 10 -channel binary and analog measurement and transient recording functionality • This Data is useful to improve their home appliances using habits. • Consequently, users can save money from electricity bills. Objectives Arduino based smart energy meter can collect real time energy consumption data. A proper interface is needed so that users are more willing to read their energy consumption. The features of this smart energy meter can be found below: A. Find out the electricity usage of each home devices B. Read the consumption data in computer C. Automatic Load Switching D. Interaction between users and energy suppliers Results & Discussion: • USB charger was connected to the 13 A socket outlet and it started to charge up a mobile phone. • The serial monitor of Arduino IDE was used to view the real time data that received by the Arduino. • Arduino was used as a data logger for about one hour. Here are the results of the test: Background-Smart Energy Meter in HK • CLP is planning to implement smart gird in Hong Kong. • combine real time energy usage information and communication technologies into the grid • provide different options and bills for consumers. • It make the gird more reliable • bring positive effect to the efficiency and safety of the power supply chain. Arduino Board • Transit the collected information to Arduino • Open-source computer hardware and software • Provide sets of digital and analog I/O pins • Can be interfaced to various expansion boards • Calculate energy consumption and show the results in computer Conclusion In order to save the environment from the greenhouse effect, reduction of energy usage is essential. citizens should increase their awareness on this matter. Arduino based smart energy meter is a useful device to let users to know their energy bills regularly. It is an easier way to get information of energy usage when comparing with the old methods. Measure the Voltage & Current • • Voltage, Current are the key parameters required to calculate the power consumption Hall effect sensor is used to convert voltage and current to small voltage output Further works In the future improving work, a more powerful Arduino board is suggested to replace Arduino UNO. The reason is that UNO board is only a basic board in Arduino platform. The analog to digital convertor (ADC) built-in UNO board is 10 bits that may not large enough for more data transfer. Temperature sensors and humidity sensors can be connected to the smart meter and form a smart house. • convert magnetic signals into electronic signals for processing by electronic circuits The meter can analyse the data and control the on/off timing of the house devices such as lighting and temperature control devices. • Activated by an external magnetic field. It can reduce the wasting of energy and the energy bills. • The magnetic field density applied around the sensor generate the output signal. • The signal is also called the Hall Voltage, VH.
