Title Microcontroller-based Infrared Distance
Measurement System
Abstract
The main applications of infrared distance is the non-proliferation principle of infrared propagation. Infrared refractive index is small when crossing other substances, so the long-distance range finder will consider the infrared. However, infrared rays will losing power when propagation. When the infrared issued from a range finder with certain power,and then hit a reflector and is reflected back till rangefinder received, there will be some loss of power, The remaining power which returned from the infrared is converted into a voltage, the distance of the reflective object can be calculated then.This paper introduces the principle of infrared range first, then uses dsPIC30F6010A as the core to make hardware design by Cadence software. The PCB board designed has many functions including the distance measurement, LCD display, Bluetooth communication, voice broadcasting and so on. Followed with a software function design to make successful completion of the circuit board of the function prediction. The final results showed that each function can work properly.
