基于超声测速技术的数字大气环境因素测量仪

Abstract

Abstract:

By many factors,traditional mechanical anemometer have been unable to meet the target currently.The use of ultrasound to measure wind speed can effectively improve the measurement accuracy,reduce errors and power consumption.The system uses MSP430 as its processing core,and takes advantage of ultrasonic properties and ultrasonic sensors to achieve the measurement of wind velocity,and realize interactive communication using the technology of ZigBee.Analysis shows that the system proposed in the article is accurate in measurement,with better accuracy at higher wind speed.

Key words: wind speed measurement;MSP430;ultrasonic sensors;ZigBee
