Design of a Digital Tilt Sensor Based on MMA7260Q

本文介绍了一种基于三轴加速度传感器MMA7260Q的倾角传感器设计,MMA7260Q输出的模拟信号输入到STC12C5410AD单片机的模拟量转换通道,经过ADC转换形成对应的数字量,从而实现了数字倾角传感器。实验结果表明,本文所设计的数字倾角传感器具有精度高、稳定性好等特点。

A tilt sensor based on MMA7260Q,which is a three axis accelerometer,is introduced in this paper. The analog output of MMA7260Q is connected to the ADC channel of microcontroller STC12C5410AD,and the analog signal is converted into digital valule using the ADC module of STC12C5410AD. Then the digital tilt sensor is realized. The experimental results show that the digital tilt sensor designed in the paper has the characters of high precision and high reliability. It has the great practical value.
