摘要
主要介绍了压阻式压力传感器的特点及在无人机上用其来解算高度、速度等参数的使用情况 ,经过温度补偿后 ,使传感器的温度特性得到了进一步的改善 ,用单片机解算高度、速度 ,达到了满意的效果 。
A characteristic of piezoresistive pressure sensor and some parameters used to compute altitude and velocity in unmanned air vehicle(UAV) are introduced.The sensor's temperature characteristic is further improved after temperature compensation,it has achieved a satisfactory result by using single chip processor to compute altitude and velocity.The application prospect of the piezoresistive pressure sensor is analysed.
