New Release! US3000 Ultrasonic Distance Sensor Module

US3000 is a micro size distance sensing module with high accuracy. The module uses a miniature ultra-low power transducer chip with patented MEMS packaging technology, based on the ultrasonic time-of-flight (TOF) principle, and is equipped with related acoustics, electricity and algorithm design, and achieves high precision measurement of distance (millimeter-level output) through the energy difference of ultrasonic echo signals, which can also be used to distinguish soft and hard materials.

Work Principle of Ultrasonic Distance Sensor

Ultrasonic distance measurement is to continuously detect the echoes reflected by obstacles encountered after ultrasonic emission, so as to measure the time difference T between the emission and reception echoes, and then calculate the distance S=CT/2, where c is the propagation speed of ultrasonic wave in the 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 is basically constant. If the accuracy requirement 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 detection.

Features of US3000

  • 1) Millimeter-level ranging error, excellent ranging stability, low power consumption, and long service life
  • 2) Can identify soft and hard materials, and can output through the serial port
  • 3) Ranging distance 20mm-60mm

Applications of Ultrasonic Distance Sensors

Ultrasonic technology has found its way into a wide range of applications, perhaps the largest in proximity detection and distance measurement. Others include liquid level detection in storage tanks, flow measurement systems and imaging products. Most of the new applications are targeting consumer electronics, automotive, industrial and robotics.
