Overview

The TIDA-00462 ultrasonic distance measurement reference design can measure the distance up to 99 inches with an accuracy of ±1.5 inches. The scope of this design is to give you a head-start in integrating our industrial ultra-low-power MCU, analog signal conditioning and power management technologies into  end-equipment systems. This design describes the principle of operation and basic design process for a low-cost distance-measuring system based on ultrasonic sound utilizing the MSP430 ultra-low power microcontroller. This design also addresses component selection, design theory and test results. All the relevant design files like schematics, BOM, layer plots, Altium files, Gerbers and MSP430 MCU firmware are provided.

Features
  • Ultrasonic technology
  • Non-contact detection and measurement
  • Maximum measurable distance: 99 inches
  • Minimum measurable distance: 6 inches
  • Maximum measured error less than 1.5 inches
  • Current consumption less than 1.8 mA at 5 V
  • Simple, low-cost system-on-chip
