Nowadays providing an oversight for server rooms has become a very important task, since a lot of services depend on the proper working of the servers, therefore the failure of the servers may result in severe pecuniary damage. To avoid this, it is important to monitor the essential parameters (temperature, humidity) and supply voltage of the server room, so the operator of the server room can intervene immediately when the situation becomes critical. For this reason, a very modern need would be satisfied by a device which would be capable of monitoring these parameters autonomously, and alert the operator if it is needed.
The purpose of my thesis is the designing and construction of a server room monitoring hardware, which is able to monitor a server room’s temperature, humidity and supply voltage, and capable to alert the operator of the server room if the situation becomes critical. The hardware is based on a microcontroller. The alerting can be done via Ethernet or SMS, the latter gives the opportunity to alert when there is no network connection. For future modular expandability the device includes a radio frequency transceiver, through which the hardware can communicate with an external sensor module. For the reason of comfortable manageability the hardware has a human machine interface. Finally the hardware has to be able to work during power failure, therefore it contains a battery and a battery charger circuit.
