Remote Accessible PC-based Data Acquisition System

Abstract

PC-based data acquisition (DAQ) systems are irreplaceable in terms of capacity and flexibility for data processing. Data acquisition systems serving IoT are a recent development trend. It is necessary to develop a remotely accessible PC-based DAQ system. In this paper, we present a PC-based DAQ system that can be accessed remotely via the internet. The system consists of several sensors connected to a microcontroller. A two-sided application is developed to set up data access, namely, a local application on the DAQ PC and a web-based application in Google Drive (GD) that can interact with applications on the PC. Local data can then be sent to GD and accessed remotely from a PC. Applications on local PCs will provide a user interface (UI) for managing the data, while those on GD will provide access from the internet. The mean time delay for sending data from a PC to Google Sheets is 2.346 s with minimum and maximum values of 0.874 and 5.863 s, respectively.

Temperature Data Acquisition System for Showcase Refrigerator Based on ESP32 and Online Remote Display

“…(13) The existing need in both industrial and commercial sectors for enhanced precision in monitoring, quicker problem resolution, energy conservation, and improved maintenance scheduling requires the integration of measurement and data acquisition systems. (14) These integrated systems, when coupled with IoT devices, enable the implementation of advanced data analysis technologies such as machine learning and predictive analytics, ultimately enhancing overall industry efficiency and productivity. This approach is particularly well suited when applied to a showcase (15) refrigerator, which serves as an industrial product utilized in commercial operations.…”
