Tips: How do ultrasonic sensors measure distance?

Ultrasonic sensors rely on high-frequency sound waves to achieve precise distance measurement. During operation, the sensor first emits ultrasonic pulses toward the detection direction. When the sound waves encounter the target object during propagation, they reflect back as echoes and are received by the sensor. The sensor then calculates the actual distance by precisely measuring the time difference between the emitted and received echoes. Translated with DeepL.com (free version). To improve accuracy, many ultrasonic sensors incorporate temperature compensation, as the speed of sound varies with ambient temperature.The sensor then calculates the distance by measuring the time it takes for the echo to return. Since the speed of sound in air is known, the distance is determined using the formula:
Distance = (Speed of Sound × Echo Time) ÷ 2
Because this method does not rely on light, ultrasonic sensors can reliably measure distance regardless of object color, transparency, or lighting conditions, making them well-suited for industrial automation, level measurement, obstacle detection, and positioning applications.
