Abstract

Objectives: To design a solar based power supply unit that can replace normal power supply in Internet of Things (IoT) devices specifically computers without compromising the efficiency of the devices. It also helps to minimize the ratio of Co2 emission of digital devices which is a big threat now days for environment. Statistical Analysis: Basically, a circuit of DC power supply unit is design for desktop computers. These computers can work on 12 volts DC power supply in green computing environment. Moreover, 5 and 3 volts are generated for initial power and internal components of the computer. Moreover, the statistical analysis is carried out on the bases of energy consumption of the user in Pakistan. Findings: The solar power can save our energy cost up to 208 volts because normal power supply works on 220 volts and new designed power supply can work on 12 volts which are too less than 220. This research work provides a potential technique for green IoT environment. Application: the proposed DC power supply unit will be very helpful to run the IoT components directly on solar systems. Moreover, because of minimum power consumption of IoT it also reduces the carbon emissions that would be good for environment.
