Implementation and Optimization of Server Room Temperature and Humidity Control System using Fuzzy Logic Based on Microcontroller

Abstract

Server room is a room used to put network devices and server computers that contain important and valuable data for the company, especially for companies or institute that already implement IT technology in its operational activities. Server room should always be monitored at all times. In this research we do the implementation and optimization on the design that we have successfully made in our previous research, as well as to test the speed and effectiveness of fuzzy control system in controlling the temperature and humidity of server room. In this research, the optimized system is able to control the temperature from 26.2C to 22.1C in 23 minutes and able to control the humidity from 67.6% to 55.3% in 6 minutes. The system is also able to keep the server room temperature in the range of normal values required with the highest temperature is 23C, the lowest temperature 21C and the average temperature is 21.7905C. While on the humidity test, system is enough to control the server room humidity in the range of normal values required. During the 24 hours of humidity monitoring, only 8 times the increase of humidity happened with an average increase value 0.65%, the highest humidity 61.4%, and the average time until the humidity returned to the standard value is 50.125 seconds, with the longest time 168 seconds and the fastest is 17 seconds. The lowest humidity value obtained is 45.9% and the average humidity is 52.44320017%. The system is also capable to send data from the microcontroller to the web server database until the data is displayed on the web page with an average delay time 0.636363636 seconds and able to send early warning notification in realtime via twiter with the average delay time of sending data from web application monitoring to twitter 0.9 seconds.
