Power the Lamps with Less Power Using Piezo-Electricity

Energy conservation plays a vital role in today& #039, s world. This paper deals with energy saving, in order to reduce the overall power consumption of our country. In this regard energy used by the street lights ought to be saved. This may be important mainly in urban areas where abundant power is wasted by the street lights even during nights when there is a minimum traffic flow. To implement less power consumption IR Sensors are used. They are kept on either sides of the road. It sends logic commands to the LEDs. When there is vehicle movement sensed the LEDs glow. This can save immense amount of energy. Thus it dynamically changes its state i. e. switching ON and OFF automatically. Day and night times are sensed and indicated by the LDR sensors. Hence LEDs are in off state during the day and glows in dim state during nights. It glows brightly only when the object is sensed. This is one of the ways to control wastage of electricity. Utilization of mankind can also be reduced. Electricity required to light the street lights can be given through the voltage developed by the piezoelectric crystals based on the piezoelectric effect. Piezoelectricity is the accumulation of charges in response to the mechanical stress applied.
