摘要
介绍了一种简单易用的数字压力传感器的设计方法,以单片机内部精确的时钟为基准,通过软件精确控制脉冲的高电平时间,使得模拟传感器的数字化稳定而精确,使得不同量程、不同分辨率要求的压力传感器可利用软件的改变来实现数字化。
A digital pressure sensor that can be easily designed and used is introduced. Since the user precisely controls the high time of pulse train via software which is based on the accurate digital time base of the micro-controller, the digital representation of the analog signal is very stable and accurate. As for different span and resolution of the sensor, the software can be changed to digitize the signal.
