Wireless digital smart energy meter based on gsm/sms technology

The traditional energy meter and manual billing system are considered complex and have many problems, including inaccuracy, ease of manipulation, and failure to pay bills on time, leading to financial losses and waste of energy and time. Additionally, it requires a large number of human operators. This paper proposes the design and implementation of a wireless single-phase smart digital energy meter based on GSM/SMS communication technology. This proposed system consists of two main parts: the consumer unit, which represents the smart meter (SM), and the control unit, which represents the server unit (SU), in addition to the (RFID) recharge system. This meter relies on GSM mobile network technology, using the SMS service between the consumer meter, control center, and the consumer's personal mobile phone to inform them about energy consumption and balance. Energy consumption information and meter readings are automatically sent wirelessly to the control center.
