代码说明:

  介绍如何简单可靠而方便测量 4~20mA 信号的文章。许多仪器仪表在远距离传送信号时,都有可能采取 4~20mA 的方式进行传送。本文对使用运算放大器或者不用运算放大器的场合都有介绍。给出了接口电阻的计算方法以及调整4mA=零点,20mA=满度的详细说明。并附有局部连接的原理图。(How simple, reliable and convenient measurement of 4 ~ 20mA signal article. Many instruments in the long-distance signal transmission, may take 4 ~ 20mA way transmission. In this paper, an operational amplifier or op amp do not have a description occasions. Shows the calculation of the interface resistance and adjust the 4mA = zero, 20mA = full scale details. Local connections together with the schematic.)

  • 超声波测距模块
    说明:  由于超声波指向性强,能量消耗缓慢,在介质中传播的距离较远,因而超声波经常用于距离的测量,如测距仪和物位测量仪等都可以通过超声波来实现。利用超声波检测往往比较迅速、方便、计算简单、易于做到实时控制,并且在测量精度方面能达到工业实用的要求,因此在移动机器人研制上也得到了广泛的应用。(Because of its strong directivity, slow energy consumption and long propagation distance in the medium, ultrasound is often used for distance measurement, such as range finder and level gauge, which can be achieved by ultrasound. Ultrasound detection is often fast, convenient, simple in calculation, easy to achieve real-time control, and can meet the requirements of industrial application in measurement accuracy, so it has been widely used in the development of mobile robots.)
