One of the good examples for distance measurement in navigation is GPS system using satellites. This data is processed to calculate distance. The speed is also dependent on the temperature. In this project, we have used an HCSR-04 to determine the distance of an obstacle from the sensor. Fig. This is converted into a distance or a level measurement. Key Applications. Distance measurement sensors are used to control or indicate the position of objects and materials. Areas of application ultrasonic sensors It means the sound wave needs to travel in 294 µs. 2 minute read . Suppose, an object is placed at a distance of 10 cm away from the sensor, the speed of sound in air is 340 m/s or 0.034 cm/µs. An ultrasonic level sensor or distance sensor bounces short bursts of high-frequency sound waves off a target surface and measures how long it takes the reflected sound waves to return to the sensor. 1.0 Ultrasonic sensing application 6 Freescale Semiconductor 3 Ultrasonic sensing application The Figure 5 shows the Ultrasonic sensing application bl ock diagram. Distance Measurement using Arduino Ultrasonic Sensor is a very easy project to measure shorter distance precisely. The working principle of ultrasonic sensor is as follows: The ultrasonic sensor is consists of Transmitter and Receiver modules.
