Abstract:
Development of a standalone device together with three application software in different
platform for server room environment monito
ring is reported. The developed hardware is
connected to different sensor networks to
detect/measure door opening, relative humidity,
temperature, flood, power line status. User can de
fine critical situation as a function of sensor
inputs. In case, a critical situ
ation is detected, the system produces warning messages to the
stored phone numbers through short messaging
service (SMS) and on-site audio visual
warnings also produces. The hardware can be
operated using the keypad and liquid crystal
display (LCD) available on the hardware itself
or using web application or using SMS. An
application runs on a computer allows the ha
rdware to connect to the internet. The data
registered in the sensors are uploaded to a web
database as a web based data log. A mobile
application has been developed to make possible the remote administration through the
mobile phone more user-friendly.User in the syst
em can be given different credentials, such
as operating device, adding new users and chan
ging critical situation detection function. The
system is capable of the authorizing user th
rough password or using iButton (in case of on-
site authorization). The main requirements to
operate the hardware are power supply (which
is battery backed up) and global system for mobile communication (GSM) coverage. The
internet connectivity is optional, if connect
ed additional functionalities are enabled.
