Temperature, Humidity, and Power Outage Monitoring System of Pamapersada Nusantara’s Server Racks

Data center is a vital location that must be managed. The room contains central devices are essential for operational continuity of the information system. Like PT Pamapersada Nusantara data center, this needs to maintained according standards. One thing temperature, humidity, and electricity because they have direct impact on IT equipment can potentially fatal if not in standard conditions. Meanwhile, being researched uses manual checks electrical power supply. problem inconsistency administrator documenting these parameters lack responsiveness repairs an anomaly occurs parameter value, real time. This research aims build monitoring system outage at which provides notifications administrators. Current similar studies generally do include sensor factor essential. installation randomly placed room, nor hot aisle or cold aisle, but server rack so temperature humidity truly represent surroundings device as ASHRAE recommend. Referring ASHRAE, 18° C - 27° while 20% 60%. starts from analysis through survey, followed by design, testing comparing with measuring tools. ESP8266 DHT22 sensors used, telegram output form notifications. Notifications sent when values conditions, every day 07.00 15.00, there 5% increasing decreasing values. results show successfully sends notification conditions met. Tests using comparisons other instruments also deviation below 2%. Measurements varying value depending occupancy its position against air conditioner
