“…For success signal transmission, factors such as signal strength, signal lossess, frequency and transmission channels are important with minimum errors. Since every Bluetooth (HC-05) module has its own IP address, even though the operation frequency of Bluetooth device is between 2.4-2.5 GHz [10], Bluetooth will only communicate with the valid IP address which is the channel connected between digital ammeter and mobile phone [11]. Therefore, Bluetooth can hardly interfere each other within the same environment.…”

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.
