Design of the Trees Height Measurement System Based on AT89S51 SCM

This paper introduces a new type of trees height measurement system based on AT89S51 microcontroller, discussed the height measurement methods and basic principles.The main controller of the system is AT89S51 SCM, use SCA61T inclination angle sensor to measure angle, use optical encoder to measure displacement, LCD real time display of measured displacement, inclination and other information, the data memory storage trees height data. In this paper, angle measurement, displacement measurement, and display part of the overall program design and describes the various parts of the system hardware and software.
