IEEE 802.15.4 / ZigBee based wireless sensor network design for monitoring server rooms

It is expected that server rooms equipped with expensive and complex devices must be reliable and stable. However, excessive environmental factors such as temperature and humidity can cause very serious effects on the devices and can lead to unrecoverable data losses or financial losses. In this study, a WSN (Wireless Sensor Network) was designed for real time monitoring the temperature, humidity, water-level, room entry, smoke and flammable gas values, and it was tested in Muğla Sıtkı Koçman University campus network server rooms. In the designed WSN infrastructure, Ardunio Uno R3 microcontroller was used at the sensor nodes to collect the data, and XBee technology based IEEE 802.15.4 / ZigBee standard was also used to wirelessly transport the sensed data to the desired place. Finally, an ASP.Net based web application was developed to graphically present and record all data collected by the WSN to the users. An authorized person has been informed with web application by e-mail and SMS for critical situations that may occur in the system.
