Radio Frequency-based Smart Control for Lighting in Public Service

Abstract

In the context of energy efficiency, the control function of electrical equipment is an essential part of saving electricity consumption. That proven by several previous studies about the control of electrical equipment that has been successful for efficiency. In this study, electrical equipment will be controlled in public service buildings, using radio frequency (RF) and the internet. The realisation of this research is to make a radio frequency prototype and an internet-based light control device. For the buildings whose location is difficult to reach by the internet, light control uses radiofrequency. While for buildings that are affordable by internet access, using the internet to control the light. In this study, the microcontroller used is ESP 8266 MCU Node and TCM 3105 FSK IC Modem for connection to the internet. Device performance in running controls measured by the delay. Delay is the time difference between the command input time and the time the device has run the command. The average delay is at an average distance of 1513 ms at a distance of 1 m, 2844 ms at a distance of 10 m, 4674 ms at a distance of 100 m, 4060 ms at a distance of 150 m and 3151 ms at a distance of 300 m. The delay value decreases because, at distances of 100, 150, and 300 connections are lost. Under these conditions, the delay value is considered empty (0) so that the average decreases. The farther the distance, the higher the percentage of unconnected, this can be seen at distances of 100, 150, and 300 m.
