INTRODUCTION



1.1 PROJECT BACKGROUD



For this project, „Digital Car's Fuel Detector‟ has been picked as the main application

regarding the ultrasonic sensors. This is due to the aspects that the technology can be used for

measuring wind speed and direction (anemometer), tank or channel level, and speed through

air or water. This ultrasonic criterion perfectly fixes the need of sensor to detect the fuels

level in the car tank. When measuring the tank or channel level, the sensor measures the

distance to the surface of the fluid.

Ultrasonic sensors work on a principle which evaluates attributes of a target by

interpreting the echoes from radio or sound waves respectively. Ultrasonic sensors functioned

particularly similar to radar or sonar. Besides that, it is also known as transceiver where they

both transmit and receive signal. Ultrasonic sensors generate high frequency sound waves

and evaluate the echo which is received back by the sensor. Sensors calculate the time

interval between sending the signal and receiving the echo to determine the distance to an

object. The illustration on how the ultrasonic sensor works based on its wave propagated is

shown in Figure 1 and Figure 2. When the wave is propagated back the time taken is recorded

and produced by the ultrasonic to be inserted in the calculation below to obtain the exact

distance travelled by the wave.







T = time between when an ultrasonic wave is emitted and when it is received Division by 2 is

because the sound wave has to travel to the object and back.
