GSM Based Emergency Calling System Operated With Solar Panel

Abstract

This project presents an emergency flexible calling system consists of GSM module, solar panel, battery sensor and fire sensor which are connected with centralized control room by wireless communication. Proposed system may be installed at any remote location where even basic emergency services are not available. It will be totally based on GSM signal strength. When a person traveling in a remote location without mobile or having mobile with switch off condition, then suppose emergency like robbery or accident or any medical emergency occurs, In such situations this system will be very useful for contact with central control room for help. In case of medical and accidental emergency happen in the coal mine, particularly when a worker doesn't have the mobile phone or having no tower in coal mine, this system may be very much helpful. System has flexible timer for calling to the control room. The System will be protected from theft attempts using alarm circuit like battery sensor. Fire sensor detect any short circuit of the system and inform about it to the control room by message and call. This system will be continuously powered through a solar panel. This system will be useful even for illiterate people as well as for coal mining worker. The purpose of this project is to help people in emergency in remote location as early as possible. This system can useful in villages having no electricity.
