For any Data Center, environment and equipment monitoring for power and cooling in Data Center is very important. Thus, all Data Center need monitoring systems to help operators in their works. Currently, each type of equipment has their own monitoring system, provided by that equipment carrier. So, to monitoring whole devices in Data Center, people have to use many separated systems. To solve this issue, we apply IoT technique for connecting all devices into one real-time monitoring system, which help to save server resource and more convenience for operator.
