Wireless Bluetooth Low Energy (BLE) Voltmeter: A Modern Solution for Remote Voltage Monitoring

Abstract

The increasing need for wireless communication in measurement systems has sparked the development of innovative tools that provide enhanced flexibility, convenience, and portability. This research paper introduces the concept of a Wireless Bluetooth Low Energy (BLE) Voltmeter, a system designed to measure and transmit voltage values remotely via Bluetooth technology. Using Arduino Nano and a BLE module, this voltmeter wirelessly transmits real-time voltage data to a mobile device, eliminating the need for traditional wired connections. The paper explores the working principle, components, and system design, demonstrating how Bluetooth Low Energy can be leveraged to create a low-power, cost-effective solution for voltage measurement. Applications of this system are discussed in various fields such as electronics, automotive diagnostics, and industrial monitoring, highlighting the advantages of portability, ease of use, and efficiency.
