本文介绍了利用PIC 16 C 63捕捉功能测量脉冲间隔的方法和超声波液位传感器的组成。
The measurement of the time between the send pulse and the back pulse using the capture function of the PIC16C63and consists of the liquid level detector have been described in this article.
在外界拉力下一个光纤布拉格光栅反射波长的漂移被转变成从另一个被压电陶瓷片调制的光栅反射的光脉冲间隔的变化。
The shift of reflective wavelength of one FBG under external strain is translated into a change in time interval of the optical pulse from another FBG drived by a PZT plate.
你还可以增加分压集成电路，比如4017，将脉冲间隔增加到你所希望的几乎任意长的时间。
You can also add divider ICs. such as a 4017. to increase time between pulses to almost any length you wish.
