This paper presents an emergency flexible calling system consists of GSM module, solar panel, vibration sensor, battery sensor and fire sensor which are connected with centralized control room by wireless communication. Proposed system may be installed near coal mine where even basic emergency services are not available. It will be total ly based on GSM signal strength. In case of medical & accide ntal emergency happen in the coal mine, particularly when the 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 protecte d from theft attempts using different alarm circuits like vibration sensor, fire sensor and battery sensor. This system will be continuously power ed through a solar pane l. This system will be us eful even for illiterate people as well as for coal mining wor ker. 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.
