Every management system is trying to make automatic, portable and remote control. In recent years many engineers and companies have been working on Automatic Meter Reading (AMR), and different media, such as radio, telephone lines, and power lines, have been used for this purpose. Energy theft and faulty meter readings are the common problem in countries like India where consumers of energy are increasing consistently as the population increases. Utilities in electricity system are destroying the amounts of revenue each year due to energy theft and erroneous meter readings. It is quite impossible to check and solve out theft and to maintain accuracy of billing by going every customer's door to door. In this paper, a new embedded technology based approach for automated energy meter reading system is proposed which enables the meter readings to be updated onto the centralized server on a regular interval basis and sends bills to customers each month. This approach is also concerned about detecting and controlling the energy meter from power theft and solves it by remotely by disconnecting the service (line) of a particular consumer. The meter readings are sent to nearby located central station using RF link and from there a computed bill is sent to consumers mobile using GSM and also displayed at consumer premises through RF Paging. An acknowledgement for the transmitted unit of energy is recorded using RF signals continuously and if there is constant delay occuring in acknowledgments, it automatically signifies as power theft and temporarily disconnects the service for that customer. It also provides the facility of electricity tamper detection. The wireless controlling of meter reading system is mainly done using arduino and GSM module.

INTRODUCTIONIndia is advancing towards the path of the digital smart country. Now most of the populations in India are the smart users, they use online methods of shopping, billing and payments. With the increasing necessity for modern equipments and a lavish lifestyle of the people, the demand for electricity has increased. This has also been a great issue in the society. With the rapid developments in the Wireless communication technology by the use of integrated circuits, it has become a trend to integrate automatic systems via wireless applications over network. Along with the advancement of technology development, research on wireless applications and remote control has become significant and popular today. An electricity meter, electric meter, or energy meter is a device that measures the amount of electric energy consumed by a residence, business, or an electrically powered device. And in such a scenario power being the main support to daily life, the tampering and losses in power is in turn a greater loss to the national economy when all the losses are added together. The traditional manual Meter Reading is n...

Face recognition is one of the most commonly used biometric for person recognition. It is used for real time identification of surveillance video images. It is also used to provide law enforcement and information security. Principle Component Analysis (PCA) and Linear Discriminate Analysis(LDA) are the appearance based techniques which are mainly used for face recognition. PCA was used for feature extraction and dimension reduction. LDA was used to further improve the separability of samples. The PCA and LDA can be combined using wavelet fusion technique. The combination of these two can be obtained using Wavelet fusion technique. It contains various levels to carry out fusion like feature extraction, matching score level, decision level, rank level.
