The basic consequences of this project is 100% efficient security system based on ultrasonic sensor technology as the customer require simple, reliable and high performance core system. The ultrasonic sensor module includes a transmitter and a receiver mounted on a rotating motor. A motor is used to allow the sensor to cover 360 degree. The ultrasonic sound energy is transmitted from transmitting device into an area of interest and this further reacts to a change in the reflected energy pattern. Basically it works on the principle of echo. The microcontroller accepts this signal and continuously monitors the receiver output of the ultrasonic transmitter. Once the distance is calculated the microcontroller checks whether the object is within the range specified within microcontroller for initiating the alert. If the object is within the minimum range the microcontroller initiates a sound alarm and also the GSM modem to send a SMS to the concerned person and camera will capture the image of object to the storage element.
