This project deals with protection of ATM from robbery. • This system uses Arduino based embedded system to process real time data collected by the vibration sensor, accelerometer and temperature sensors. Once the robbery is detected, the Siren will start alerting the public. The door of the ATM will automatically shut close. • Solenoid valve is used to leak the gas (Chloroform) inside the ATM chamber to bring the thief into unconscious stage once he inhales the dose defined. • GSM Modem is used to send message to the nearby police station, corresponding bank manager and Security Officers. Once the bank officials or Police come, they can disable the system by entering a password then open the ATM door and catch hold of the Thief. METHODOLOGY The basic methodology of the project is when the code is dumped into the board and powered up, there are 3 major parameters that are checked continuously, they are: • Vibrations: Vibration sensors attached to the ATM machine will trigger when the robber tries to cut the ATM machine using any of cutting tools such as hacksaw or any drilling machine. This generates a lot of vibration, more than the average activates in the ATM booth. • Temperature sensor [LM35]: Few of them are placed just behind the cash withdrawal chamber. There is a possibility that the robber can use a gas cutter to cut through the cash chamber rather than using a cutter, then temperature could easily exceed 400 degree centigrade. The output of sensor is in the form of analog voltage. • Accelerometer [ADXL335]: The displacement of the machine measured by the 3 axis accelerometer. Finally there is also a chance that he can try and lift the whole of the ATM machine. Hence once the predefined threshold level is crossed the microcontroller is trigger indicating the ATM machine is being tried to shift out of its place. • If either of the above three things were to happen there is a trigger to the Arduino, the door of the ATM is automatically shut down. The chloroform gas is released into the chamber, It is reported that exposure to chloroform at 920-1,100 ppm for 2-3 min resulted in dizziness .Hence meanwhile the PPM level of the gas is continuously measured and monitored. When this level reaches the peak level beyond which it could be lethal to the person inside, the valve is closed. • The next step, the siren goes on, alerting the public. An SMS is sent to the concerned persons using the GSM module connected to the microcontroller. The SMS could be sent to police, bank manager and the security guard. We could keep displaying the PPM level and status of the emergency level. • Now there is need of the bank manager or the police to come and open the door and apprehend the thief. Once the code is accepted, the door is ready to be opened. But before that there will be gas in the chamber, this can cause effects to the outsider, so there is as exhaust fan setup at the top of the ATM chamber, this is turned on. Once the PPM level comes down below certain acceptable level the door opens. Then the alarm is disabled and the board is reset again. FLOW CHART START VIBRATION SENSOR TR. TEMP SENSOR .

Moreover the development board used and the software used are Opensource, hence this project provides an option for future enhancements. It uses GSM technology which is very popular and reliable. We have provided a way to catch hold of the thief which plays an important role. FUTURE IMPLEMENTATIONS One other major trouble for the customers is that they could be assaulted in the chamber for the cash or the PIN, there are also some reported cases. There is an idea that are planned to be implemented in our next prototype. Firstly we can try and help the victim if he is inside the chamber, kept as hostage. We can install a panic button, if pressed by the victim the chamber gets immediately filled with fog so that the thief can’t see anything. And secondly we can use a high pitched very irritating sound so that both the parties can’t do anything but cover their ears. Then we can introduce the chloroform gas and reaper.
