Question

Implement a new instrumentation system (sensors and indicators) that show the fuel level.

These sensors and indicators will be used for monitoring and for controlling these parameters. Design circuit and indicate which sensor to use.

Answer 1

ultrasonic Sensory . . o d we driver 2. This system will be implemented as hardware with seusing capabilities of the feit fuel level using . . The ultrasonic sensors will determine the distance from the tank top till the surface of the fuel and display it directly to ... the display. If the fuel level rachees below the threshold the system will automatically alarm and Judicate to the driver : Metliodology The whole block diagram h can be divided into s pött: a) power supply As the Olp to microcontrollen is sv. .. we have used as a voltage regulator. which has fixed Vollage of su (6) micro coutrelles, At mega 16 is a 40 pin wide DIP : Dual in Line) i package clip. The micro controller i also to available in surface mount package. ② Sensori It is a type of Tran receiver ultrasonic seuson, works on the principle in echo. The celtrasonic waves are sent to an object and the reflected waves are received on Thure required for the reflected waves are recorded and distance is calculated by knowing the

speed of transmitted waves. a Buager When the fuel is below the threshold ralie then the buzzer will start .. buasing the audio signala System Architecture & fuel left aut Distance roku Loca ♡gateway Buizer. Owner . The co for time and system will contain two altrabonic Laasonic moclules to show updates, a micro SD card data acquisation and saving and realf Clock (RTC) to give accurate time alla date -

e ha sonic seasons are characterized by low cost. and posiblility of being used in environme where it is not possible to use more complese sensors as camera, laser devices, optical sensors In this we can employ HC SR-04 which is ultrasonic electric telemeter. This can measure . a distance within 0.03-3mt. A first sus pulse is applied trough the pin : SIG of free module which triggers the : transmitter to . generate 40kHz oultra sound Signal. At the moment receiver Catches a ware it generates a high pulse width with which corresponds to the time that the signal takes to reflect back, By using this pulse width we can. measure the distance as well as the fuel level.
