How Ultrasonic Sensors Work
Transmission of Sound Waves: The sensor emits a burst of ultrasonic sound waves (typically around 40 kHz) from a transmitter transducer.
Reflection of Sound Waves: The sound waves travel through the air and reflect off an object.
Reception of Reflected Waves: The reflected sound waves are detected by a receiver transducer in the sensor.
Time Measurement:
The sensor measures the time it takes for the sound waves to travel to the object and back.
Distance Calculation: Using the speed of sound (approximately 343 meters per second in air), the sensor calculates the distance to the object based on the time measured.

Applications of Ultrasonic Sensors
Distance Measurement: In robotics, for obstacle detection and avoidance.
Level Sensing: In tanks and silos for liquid or granular materials.
Object Detection: In industrial automation to detect the presence or absence of objects.
Proximity Alarms: In parking assistance systems to warn drivers of obstacles.
