Smart Mirror for Home Automation This research describes the design, construction and working of the smart mirror. Every morning our day begins by watching ourselves at least once in mirror before leaving our homes. We interact with it psychologically to find out how we look and how our attire is. Smart Mirror or Magic Mirror is one of the applications of Raspberry Pi. A computer screen embedded in mirror looks very futuristic. The Raspberry Pi stays at back scenes and controls the data displayed on mirror. While looking at mirror, the user can look at various notifications from social sites as well news, weather forecast and more things. Such mirrors can be programmed to work as control home appliances by voice input. The Raspberry Pi is connected to monitor via HDMI as well as it also has built-in Wi-Fi and Bluetooth interfaces so we can just swipe music and videos to mirror.

Smart Water Level Indicator The Water Level Indicator is beneficial to the public, especially to residents living in rivers. This technology can provide early warnings to residents when the water level is occupying a dangerous level and facilitates workers who control the dam of the river. This technology can alert early through sirens and notifications / messages via smartphones as well as to the river dashboard controllers capable of controlling water gates through their smartphones. The worker who controls the dam of this river no longer needs to go back to the dam's door control house to open the water dam door. Workers who are in charge of controlling dam need to stand in one place only to open their smartphones and control the dam's doorway using the fingertips. To the people living in the river, they do not have to worry about the floods that will happen in their area. They will get an early warning about the flood at any time even when they are sleeping. They will get the warning via notification on their smartphone and siren is places in a certain area to produce a loud noise so that residents can be prepared to face the disaster. It is expect that the Water Level Indicator is able to take a step further and can be use as best as possible and can help the local community

Solar Tracker The generation of power from the reduction of fossil fuels is the biggest challenge for the next half century. The idea of converting solar energy into electrical energy using photovoltaic panels holds its place in the front row compared to other renewable sources. But the continuous change in the relative angle of the sun with reference to the earth reduces the watts delivered by solar panel. Conventional solar panel, fixed with a certain angle, limits their area of exposure from the sun due to rotation of the earth. Output of the solar cells depends on the intensity of the sun and the angle of incidence. To solve this problem, an automatic solar cell is needed, where the Solar Tracker will track the motion of the sun across the sky to ensure that the maximum amount of sunlight strikes the panels throughout the day. By using Light Dependent Resistors, it will navigate the solar panel to get the best angle of exposure of light from the sun.
