In other hand, the in service classical energy meter type (induction type) suffers from well-known measuring errors. The above problems result in two significant points, waste of much money due to the large number of employees (meter readers) and the weakness in electricity management which results in lack in electric power. This project provides an excellent solution to the problems mentioned above where the system has been designed based on the use of energy smart meter to read electrical energy consumed to get an accurate reading. Then the energy reading is sent to the control centre in the electricity department based on GSM/SMS technology. The system in the electricity department receives readings and makes processing operations on them and extracts the bills that must be paid by the customer. The system also sends a message to the own customer mobile phone which contains the current bill, due bill, and total bill every two months have to be paid. In addition the system has the ability to print out a hard copy of the customer bill. Finally the proposed system has the ability of automatic power outage if the customer refrains or delays for certain time in paying the bills by means of an SMS.

INTRODUCTION The world is changing towards automatic wireless technologies, which prefer not only reducing human efforts but is helping in making systems automatic and efficient. A system is said to be intelligent when it can decide what to do without any instruction and can work automatically. An Electric or Energy meter measures the total electrical energy in units used by the appliances which consume electrical energy from the main power supply. Electromechanical and Electronic meter are two types of meter Available in the market to measure the unit consumption. Electromechanical meters are commonly used in village areas, where the uses of modern technology are not as high as it is in cities. Electromechanical meters have become out of date nowadays. Electronic meters replace electromechanical meters. This meter consists of LCD/LED to display the reading. Calibration Led is used on the meter which shows the units consumed. Manpower is required to read the meter and note down the reading. The reading on the meter is increasing which is used to generate the electricity bill. An IOT Based Smart Electricity Meter and billing System does the same
