| 总结: | The purpose of this project is about to design and build a device that using the
ultrasound, which one of the ways of measuring distance. This about that can be
measured by standing just at one place which means no need to measure for along
the distance. This gives benefit in saving time and energy during measuring the
distance. This device which the ultrasonic sensor is used and it is separates into the
two kinds, the transmitter and the receiver. Both this sensor is used to transmit and
receive the 40 kHz ultrasonic signal that used to measure the time. This Ultrasonic
Range Meter detects a reflected wave from the object after sending out an ultrasonic
pulse. The detection is done to detect the received ultrasonic signal. The
microcontroller, PIC16F873 is use as interfacing to the output display. By measuring
the time which returns after emitting a sound wave, a distance to the object is
measured. This project gives the improvement on reading technique compare by
measure the distance manually. Basically, this project is separate into three main
parts. The first one is to finds and designing the hardware that required and related to
the project, the second part is to construct and develop the hardware together with
testing and troubleshooting. Then the third is designing and develop the software part
and combine together with the entire of hardware component developed. In this
project, the main electrical and electronic component is use including ultrasonic
sensor module, PIC Microcontroller and also Liquid Crystal Display (LCD). This
priority of this project is to improve the distance measuring technique to be more
easier and saving time and give another benefits and soon the conception of this
project could be apply to other applications such as distance detector for car reverse
or parking sensor and also for robotic range finder. |
