Development of MEMS and GSM based ATM Security System

The project is designed using MEMS technology. According to this technology the communication takes place between two devices - MEMS and microcontroller. The MEMS sensor is a device which identifies the tilt produced by the ATM machine due to the irregular movement that occur during theft. This paper makes use of MEMS as a sensor device which identifies the tilt Produced by the ATM machine due to the irregular movement that occur. The design basically consists of a MEMS sensor which identifies the tilt by the machine and activates the microcontroller to start with the following sequence which shuts the door using stepper motor and sending SMS to vigilance using GSM system is involved. This system stops any sort of robbery by taking MEMS functional bock as its input. It is the MEMS that is activating the total design by identifying the tilt caused by the breaking down during the theft of an ATM machine. Once the microcontroller is activated a sequence is started which involves shutting of the door using stepper motor and alerting the vigilance system by a SMS using GSM.
