RANCANG BANGUN PROTOTYPE PENERANGAN JALAN UMUM CERDAS DAN EFEKTIF

In the development of Public Street Lighting, the operation of Public Street Lighting can be done with photocell (LDR) and the use of large electric power in general street lighting can also be suppressed by reducing the intensity of light when the path is not passed by an object then the light intensity becomes 50% and if Path passed by an object then the light intensity to 100% that is with the help of ultrasonic sensor. And on the input voltage by using solar cell. So that the measurement of current and voltage on the load based on the object passing. It is known that current and voltage obtained when there is no object passing the road that is 0.15 A and 4.02 V smaller than the object across the road that is 0.2 A and 6.63 V, when the object crosses the road with the speed Which has been set that is 20 km / h and with different length of the vehicle so that the time obtained objects that crosses different sensors. Although the longer the vehicle and the longer the object passing through the sensor does not affect the current and the voltage used in the load remains constant. And with the capacity of the battery possessed with a 6 W lamp load capable of burning for 12 hours
