A Novel Lo-Ra-Based Wireless Communication Module for Industrial Data Acquisition-Telemetry

The development of communication technology must be implemented to improve the efficiency of industrial systems. One promising approach is the use of Ultra High Frequency (UHF) modulation for long-distance communication between sensors and industrial controllers. This study aims to design and implement a UHF communication module that can be integrated with conventional temperature transmitters and Siemens industrial controllers to enable effective remote measurement and monitoring. The implementation of the UHF communication module considers critical aspects such as reliability, data throughput, and latency for industrial applications. Testing and evaluation were conducted to assess the module’s performance, including measurement variations and distance testing between the systems. In addition to field trials, the module was evaluated in a controlled environment at the Instrumentation Laboratory of Institut Teknologi Sepuluh Nopember (ITS), where it transmitted RTD (Resistance Temperature Detector) temperature data. Key findings indicate that the system achieved reliable wireless communication up to 150 meters, with a bit error rate (BER) of 1.2×10⁻³, signal-to-noise ratio (SNR) above 14 dB, and packet loss below 2% across the tested range. These results confirm the reliability and accuracy of the module for industrial telemetry applications. With specially designed UHF transmitter and receiver modules, the system aims to enhance measurement performance, reduce downtime, and support prompt decision-making in complex industrial operations. The proposed solution offers a cost-effective and scalable communication platform suitable for diverse industrial environments.
