Development of Data Acquisition System for Collecting and Processing Data

The big data collected from IoT (Internet of Things) devices have difficulty sending to the cloud server due to the finite resources. To get over such limitation, edge computing is suggested. In this paper, we propose data acquisition device (DAQ), executing data collecting and computing functions, programmed to conduct the target works like sending message to the other DAQ device and receiving data from the several kind of PLC(Programmable Logic Controller). DAQ communicates with gateway using LoRa or WiFi connectivity and is using BLE to configure its environment.
