Abstract:
This research presents the development of IoT system that can store temperature and humidity data of server room via network. Can Monitor and Manage notifications through Dashboard Monitoring Systems. The IoT system created consists of 10 IoT Devices. Each IoT Device consists of Microcontroller (MCU) type ESP8266, small OLED display, DHT temperature and humidity sensor (8 sets of DHT22 and 2 sets of DHT11) installed in 3 server rooms. The data transmission in the built IoT system uses MQTT via Wi-Fi network, send data to MQTT broker in IoT Server, then convert data to IoT Server Time Series Database and Display at Dashboard Monitoring Systems.
The research shows that the system can collect temperature and humidity data from IoT Device in the server room of the Computer Center. Burapha University and display the results as Data Visualization Through a web browser (http://dcr-sensor.buu.ac.th) to check and analyze temperature and humidity. If the temperature and humidity values of the server room has exceeded the specified critical point. The developed IoT system can alert users via email, Line, and Microsoft Teams. Reduce the obligation and the error of data from data storage by taking notes on paper documents can reduce the budget for the server room temperature and humidity monitoring system
Suggestions from the research show that since the server room of the Computer Center does not use Precision Air Condition System, especially according to the Data Center standard. Therefore should use more IoT devices. In order to use the temperature and humidity data obtained for further analysis and analysis of the efficiency of the server room environment
