Ultrasonic Rangefinder Based on P89LPC932

Abstract:

In order to overcome the limitation, some traditional distance measurement methods in some special occasions go beyond measure flaw. This design centres on P89LPC932 and realizes non-contact air measurement by use of an ultrasonic sensor, which fully considers the close relationship of velocity and temperature, thus temperature compensation, further get measurement distance about 700cm, optimal precision at 1%. This design has some features, such as the strong anti-jamming capability, simple installation, small size, low power consumption, easy to embed in other system.
