Design of server room temperature and humidity control system using fuzzy logic based on microcontroller

Server room is a very important asset for a company because in there are servers that contain applications and company databases that are very valuable for the sustainability of a company, therefore the condition of the server room such as temperature, humidity, power and all IT equipment in this room should always be monitored in real time. One way that can be used to control and monitor the temperature and humidity of server room is to use an Internet of Thing (IoT) based system. This research proposed the design of server room temperature and humidity control system using fuzzy logic based on microcontroller Wemos D1 as an infrared transmitter remote control to control temperature and mode setting in Air Conditioner to control temperature and humidity of server room. Fuzzy logic based on microcontroller for control the temperature and humidity of server room was successfully designed and successfully implemented into microcontroller with simulation test results using matlab obtained the value that match with the results on the microcontroller with average AC Temperature Set output deviation 0.03500 and average AC Mode Set output deviation 0.01225. The system is also designed to be able to monitor data temperature, humidity and electricity voltage online using the website and can provide early warning message through social media twitter.
