Bluetooth embedded digital ammeter with android app data logging

Abstract

Monitoring current supplies to light emitting diode (LED) luminaires is one of the reliability tests performed manually. Bluetooth (HC-05) embedded digital ammeter was proposed to acquire currents of a badge of LED products and hence, quality can be assured. Android App was designed to remotely record the current supplies to the different models of LED products and checking if the current measured is within the allowed range. The current data can be further analysed to control the quality of the LED luminaires produced. The pass and fail-current range can be set in the digital ammeter for alerting abnormal current measured by the operator. Therefore, IOT embedded digital ammeter will help in monitoring data consistency of LED products and improve quality assurance procedure.

Validation of android-based mobile application for retrieving network signal level

“…In the 21st century, communication system applications are utilized in the day-to-day activities of human lives, these include telecommunication, terrestrial television, transportation (maritime & air), military and security. Communication system engineering applications have evolved from the era of line telegraphy, radio telephony to real-time communication through the use of sophisticated smartphones that can perform various tasks including online shopping, cloud gaming, financial processes, controller, measurements and mapping etc [1][2][3][4]. Contemporary smartphones are versatile portable computers-on-chip that exploit the flexibility conferred on them by the existence of operating systems in this case Android that manages and controls operations of the smartphones depending on the architecture.…”
