In this system, we are using sensors like IR sensor, LDR sensor, Temperature sensor, smoke sensor, and the vibration sensor. The IR Sensor is used to monitoring the person IN/OUT in the ATM room. If more than 2 person enters the ATM, then it gives an alert to the user. LDR sensor is used to monitor the light intensity inside the ATM room. If the LDR output values are lower than the threshold value, then the ATM room light will automatically switch ON. Temperature Sensor is used if the temperature inside the ATM room goes below the specified limit, then the AC can be switched off, thus we can have a power saving. Smoke Sensor is to monitor the smoke level in the ATM room. If the smoke sensor value crosses the threshold value, the buzzer will get ON automatically. The Vibrator Sensors used to monitor the ATM when try to break. This will lock the door and send the message to the police station. The whole system relates to the IoT. So the user can monitor the ATM (like temperature level, Smoke) from anywhere and also can control the loads (Like AC, light, door) from the long distance
