| dc.description.abstract | The Internet of Things (IoT) Based Systems have improved the way of life of companies as
well as individuals. Through interconnected objects via intranet and Internet, IoT
technologies enhance the productivities of businesses by reducing the wastage of time,
reducing the expenses of the businesses by its low-cost property. The IoT is empowered by a
system of detection, actuation, control, and cloud storage. IoT technologies should be applied
to monitor the change of the value of valuables like temperature, voltage, gas and liquid level,
etc.; it helps to get the record of the change in the value of the valuables detected. The
proposed system was developed to monitor and control data center temperature through
ESP32 board, DHT22 module, relays and ThingSpeak cloud. To significantly reduce the
power consumption of the cooling devices, the system uses a cooling device backup which
can be controlled by a microcontroller through a smartphone over the Internet. Moreover, the
system assists the data center manager by automatically switching on the backup in case of
the failure of one working cooling device. However, an email address and SMS are sent to
the data center manager at any time when there is a collected value that is not in the normal
temperature range. As a result, the project enhances the productivity of the company by
reducing the cost expended in the data center infrastructure, and by reducing the activities
performed by a data center manager. | en_US |
