ULTRAULTRASONIC DISTANCE MEASUREMENT WITH THE MSP430

Project Abstract / Summary : ULTRASONIC DISTANCE MEASUREMENT WITH THE MSP430


UNIQUE

This application report depicts a separation measuring framework in view of ultrasonic sound using the MSP430F413 ultralow-power microcontroller. The framework transmits a burst of ultrasonic sound waves towards the subject and after that gets the relating reverberation. The MSP430 coordinated simple comparator. Comparator A is utilized to distinguish the entry of the reverberation to the framework. The time taken for the ultrasonic burst to venture to every part of the separation from the framework to the subject and back to the framework is precisely measured by the MSP430. Accepting the rate of sound in air at room temperature to be 1100 ft/s, the MSP430 processes the separation between the framework and the subject and shows it utilizing a two-digit static LCD driven by its incorporated LCD driver. The separation is shown in inches with an exactness of ±1 inch. The base separation that this framework can gauge is eight crawls and is constrained by the transmitter's transducer settling-time. The most extreme separation that can be measured is ninety-nine inches. The abundancy of the reverberation relies on upon the reflecting material, shape, and size. Sound-engrossing targets, for example, covers and reflecting surfaces under two square feet in region reflect inadequately. The greatest quantifiable reach is lower for such subjects. On the off chance that the plentifulness of the reverberation got by the framework is low to the point that it is not recognizable by the Comparator_A, the framework leaves range. This is shown by showing the blunder message E.
This concept can be applied in four wheelers to avoid accidents.

Why did you choose to work on this project topic : The reason for choosing our topic as 'Ultrasonic distance measurement with the MSP430' is that to create some awareness in the traffic. We have planned to use this MSP430 in four wheelers because there are many accidents are happening in the current life. To avoid these injuries we have discovered an distance measurement by using sensors in cars.

Project Highlights : It is mandatory that if our project wins the contest there will be a new chance to us to innovate something new in our country and the project what we are doing now will be very usefull for upcoming generations. Now a days there are many accidents are happening in the roadways. If our project comes true in real life then some of these things can be secured.
