In today's world we all are well acquainted with our nation's energy scenario. The energy demand by far outstrips the energy supply. In order to balance the ratio between energy demand and supply, load shedding is performed. We witness daily power cuts in domestic as well as industrial sectors, hence energy saving is the need of our hour. Not only the available power is less than the demand but also it is being wasted on a large scale . The wastage is in the form of unnecessary usage of lighting, low power factor and similar other factors. Keeping this thing in mind we have developed a "Street light controller with status feedback". The main objective of our project is power saving which is 1. by reducing voltage in various steps 2. By reducing voltage through semiconductor switches like thyristors, SCR by controlling the firing angle 3. By switching the street light in various combination at various time (RYB). Also power factor correction is performed so that losses can be minimized. Our project is an advanced microcontroller based system which precisely controls various loads in various settings like offices, malls, public parks etc.
