Smart Energy Monitoring using ARM Cortex

Abstract

Nowadays, the demand for electricity increases due to an abrupt increase in population. In the existing system, the physical energy meter reading is taken, which is inefficient and is an outdated concept. This will require a large number of laborers. The person comes from the electricity board to the consumer's house for taking the readings from the energy meter and then, has to calculate the amount of energy consumption. This process is time-consuming and is a waste of manpower and will cause a lot of errors. A solution is, to implement a smart energy meter that will monitor energy consumption in terms of unit cost on an hourly and daily basis, in order to reduce human errors, physical labor,s and to improve the efficiency of the system. The proposed system will solve all the problems which are in existing energy meters. The proposed work calculates the energy consumption and sends the data to the consumer’s mobile via the global system for mobile communication (GSM) module, and the Bluetooth module HC-05 will also give them information on Android application, only when the Bluetooth is in the range of 100 meters from the smart meter. Both of these modules are connected to the ARM Cortex Board (AT91SAM3X8E). It has low power consumption and lower cost. The smart energy meter will also have a display unit that will show the real-time running data and consumed unit. When there is no supply from Maharashtra State Electricity Board (MSEB), then the smart meter will automatically switch to the inverter or battery backup through the relay. The proposed system is user friendly and has better efficiency than the existing energy meter.
