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.
