The Application of Wireless Communication in IOT for Saving Electrical Energy

Haider Alrikabi, Abdul Hadi Alaidi, Khalid Nasser


Energy consumption is a huge problem in Iraq, especially in government institutions. Many devices continue operating even after working hours. In this case study, by using IOT technology, we shall show it to be more efficient if we can control the main devices that are consuming a large amount of power.  Internet of things (IOT), therefore, is an exciting solution for managing energy consumption in Iraqi government buildings.

The proposed system has been designed to wake up the devices to start operating at 7:00 AM. 7:00 AM is the standard start of the working day in Iraq. In our proposed system, the case study has been taken based on the universities and institutions. In the universities and institutions, the working day ends at 8:00 PM. This is when our proposed system is designed to power off the main devices. In addition, after 8:00 PM and before 7:00 AM, if there is any device still in operation, the system will send a notification to the manager of the institution.

Our proposed system has been designed using Arduino mega as a main controller. Also, the module SIM800L GSM has been used to make the communication for notification cases, and the Relay 8 CH has been used as electronic switches for the devices.
