Sensing System for Technological Data Collection in Industrial Internet of Things: Non-Cloud Based Solution

We propose a sensing system for the acquisition of technological data in the concept of the Industrial Internet of Things. One of the most demanding requirements of the Internet of Things, i.e., increased security risks of connecting devices to the Internet, is mitigated by designing a system that does not need to be connected to the cloud. All received data are stored on the SD card of the sensing system and in the client database after connecting to the sensing system web page, i.e., it operates in offline mode, and optionally on the client device when accessing the HTTP or HTTPS server of the sensing system in local area network or wide area network, respectively. We consider wire and wireless connection of sensors fulfilling the basic requirement for Low Power Wide Area Networks, i.e., low consumption, and user-friendly data visualization. By developing a prototype of the heated filter insert, we successfully demonstrate the proposed sensing system is an effective secure solution of technological data collection in the Industrial Internet of Things ecosystem.
