US3000 Ultrasonic Ranging Module
New Product Recommendation | US3000 Ultrasonic Ranging Module
US3000 is a high-precision miniature ranging sensor module. The module uses a miniature ultra-low power transducer chip with patented MEMS packaging technology. Based on the ultrasonic time-of-flight (TOF) principle, coupled with related acoustics, electricity and algorithm design, it can achieve high-precision distance measurement through the energy difference of ultrasonic echo signals, and output millimeter-level distance information, which can also be used to distinguish soft and hard materials.
Introduction to the Principle of Ultrasonic Ranging
Ultrasonic ranging is by continuously detecting the echoes reflected by obstacles encountered after ultrasonic emission. By measuring the time difference T between transmitting and receiving echoes, the distance S=CT/2 can be obtained. C is the propagation speed of ultrasonic waves in air.
Since ultrasonic is also a kind of sound wave, its sound velocity C is related to temperature. In use, if the temperature does not change much, it can be considered that the speed of sound is basically constant. If the distance measurement accuracy is very high, it should be corrected by temperature compensation. After the speed of sound is determined, as long as the round-trip time of the ultrasonic wave is measured, the distance can be obtained. This is the mechanism of ultrasonic ranging.
