摘要
Abstract
In order to overcome defects of some traditional distance measurement methods can't be measured in some special occasions, a non-contact air measurement method is realized by use of an ultrasonic sensor based on P89LPC932. The design performed temperature compensation based on the close relationship between velocity and temperature to further gain measurement distance about 700cm, optimal precision at 1%. This design has some features such as strong anti-jamming capability, simple installation, small size, low power consumption, and it is easy to be embedded to other systems.关键词
