With the development of communication technology and the coming of Industry 4.0, Internet of Things (IOT) devices are being widely applied in industry and manufacture. In this paper, wireless industrial devices based on the IOT are investigated. Sensor technology and wireless technology are regarded as the development trends of the industrial IOT. Therefore, we designed and studied three kinds of industrial wireless monitoring and measuring devices whose core components are capacitive sensors. These devices can be applied to paper measurement, gesture recognition and liquid level measurement, which address three industrial requirements. Each device is designed with a complete structure, and they can operate automatically and independently. Each sensor device is a node of a wireless network and a component of an industrial dynamic detection network. The purpose of this research is to propose several models of wireless industrial measurement devices that are helpful for real-time industrial monitoring and that improve the efficiency of industrial production.

随着通信技术的发展以及工业4.0的到来，物联网（IOT）设备已广泛应用于工业和制造业。本文研究了基于物联网的无线工业设备。传感器技术和无线技术被视为工业物联网的发展趋势。因此，我们设计并研究了三种以电容传感器为核心部件的工业无线监测和测量设备。这些设备可用于满足三个工业要求的纸张测量，手势识别和液位测量。每个设备都具有完整的结构设计，并且可以自动独立运行。每个传感器设备都是无线网络的节点，也是工业动态检测网络的组成部分。
