Abstract

automatic meter reading and improve the existing system to an Internet of things using MQTT Protocol. The system will be read power consumption through help of current sensor, process it and calculates power consumption and send it to server. It is a combination of a current sensor and a GSM (Global System for Mobile Communications) module. The module chosen is having capability of doing high speed data processing and complete stack of GSM communication. By the virtue of blooming automation industry and wireless connectivity, all the devices within the home can be connected. This improves the comfort, energy efficiency, indoor security, cost savings of the home. Small and constrained embedded devices are used to remotely monitor the conditions within home and control the home appliances. In such case, power consumption and network bandwidth become a major concern. We need a low power device that transmits messages through a less verbose protocol. Owing to the ubiquitous availability of Wi-Fi, all the appliances within home can be connected through a common gateway. This paper presents an overview of a light weight Message Queuing Telemetry Transport (MQTT) protocol. The product improvement incorporates choice of fitting stage which gives appropriate learning and advancement stage for programming advancement. Gives essential programming framework to begin and concentrate on application advancement. The picked stage is Sierra Wireless Open AT application stage which depends on Open AT RTOS. It gives bland drivers to begin with and appropriate troubleshooting support. The stage itself is industry standard and gives a decent chance to figure out how to build up an Industry standard item. The system developed is a fundamental electricity power consumption data logger unit with the help of above technologies.

Introduction

A sensor is a device which detects and converts current to get an output voltage, which is directly proportional to the current in the designed path. When current is passing through the circuit, a voltage drops across the path where the current is flowing. Also, a magnetic field is generated near the current carrying conductor. These above phenomena are used in the current sensor design technique. These sensors are these days being used widely in almost all the industries because of their vast applications and the type of output they provide which can be controlled and can be used for different applications.

Conclusion

In this project, we have done review of various existing techniques of automatic meter reading, monitoring and alerting system. We have gone through various useful technologies, algorithms and methods used. Every system has their own importance; different authors have tried different methods based on applications. The proposed system is implemented and tested with different scenarios. As the system development is done on a widely used OpenAT GSM platform we get a chance to get into GSM GPRS domain. Present system provided an entry point for use of GSM GPRS application in various domain which can be widely elaborated in future.
