Question

As an engineer, you have been asked to design a digital measuring tape. The designed measuring tape should operate in a wide temperature range, specifically in the range from -10

°C to 65°Cfor the ambient temperature. The power supplied for the system should be between 5 to 9 V DC.The ultrasonic sensor used for the system should have a range from 25 to 100 cm. The accuracy of the measurement should be better than +-0.25 %. The unit price of the sensors used for the system should not exceed 5 KWD. The height of the measuring tape should be between 10 to 20cm. b) (5pts) Ultrasonic sensor is used in many systems in life. Give minimum three application where this type of sensor is used.
