Performance Analysis of Arduino-Based Data Acquisition Systems: A Comparative Study Between Wired and nRF24L01 Wireless Communication using LabVIEW

Abstract

This study presents a performance evaluation of data acquisition systems (DAQ), focusing on data transmission via wired and wireless communication channels. It provides a comparative analysis of these two methods based on critical factors such as speed, security, and flexibility. For the experimental implementation, an Arduino Uno microcontroller was utilized to develop both wired and wireless data collection frameworks. Data was gathered from multiple sensors, including temperature, gas, and light intensity (LDR) sensors. The LabVIEW software environment was employed for data processing, real-time monitoring, recording, and simulation. The NRF24L01 transceiver module was integrated to facilitate wireless connectivity. Simulation and experimental results demonstrated that while the wired system offers higher data transfer speeds and enhanced security, the wireless system provides significant mobility, ease of installation, and sufficient accuracy for control applications. The findings indicate an average temperature difference of 0.7°C between the two transmission methods, with wireless data showing high precision despite potential signal degradation in wired cables over distance. Ultimately, the study confirms the effectiveness of Arduino and LabVIEW in building versatile DAQ systems suitable for utility and home automation sectors.
