Design of a tilt angle measurement and control system

A design of a tilt measurement system and control is presented in this paper. Inclination angles are measured by a MEMSIC 2125 dual-axis accelerometer. The design consists of both hardware and software. The tilt angle in one-axis is measured by the accelerometer which is mounted on a stamp board and connected to a microcontroller. The tilt measuring system is mounted on a plate. When the plate is tilted, the tilt angle is measured by the accelerometer. A basic stamp II microcontroller reads the accelerometer measurement and sends a signal to a servo-motor to implement the desired control action by adjusting the plate to the stable position (0-degree). The ambient temperature is measured by the accelerometer as well, and both the tilt angle and temperature measurements are displayed on an LCD.
