The main objective of the project is to propose a system where we will monitor the battery charging percentage/battery charging status by using a current sensor and 8051 microcontrollers. Now-a-days, there is a tremendous demand for energy and similarly demand for portable energy sources. As a result, it becomes very important to save energy. The portable devices which stores energy such as mobile phone’s battery, laptop’s battery, power bank, etc., uses rechargeable cells. These cells can be charged again and again. But many-a-times this thing happens that people put their phone/laptop etc., on charging and forgets to unplug the charger once battery is fully charged. Under such circumstances there is possibility that the device by get heated. Also due to excessive heat the device may explode. Excessive charging and excessive heating of the device may lower down the complete performance of the device in long run. It can be concluded that the energy is flowing through the mains towards the charger but the device is not accepting the charge. So, we can conclude that the energy is being wasted. To stop such wastage of energy our circuit is introduced. We have used a current sensor and a relay switch in our system which will break the supply coming directly from the mains. This system will be placed in the supply box/switchboard and then the adapter of phones/laptop will be attached to it.
