PROJECT: Efficient power saver for street lights using LDR, RTC, LEDs light with solar power

The project aims to keep the power usable with the maximum scope of use and real time clock and the sensors. In this competitive world, no one can work without time to carry out his daily activities manually without fail. Most importantly, he forgot to switch off the lights in the room where it was not required. So even the waste of power to some extent. This can be seen widely in the case of street lights and advertisement boards. This project provides the best solution for power losses. Additionally, the manual labor was eliminated completely. This project includes different time and excluded, working light. Users can write programs live time in accordance with their requirements and these times will be stored in the RTC and cannot be deleted if the user does not want to change it again. We will also provide the mini projects for eee 3rd year students and guide them to choose the best project.

Available systems already exist on the market for the purpose of energy savings in the case of street lamps. But these systems can be equipped with LDR or RTC to operate them. If the project is implemented without the use of LDR, street lights will be switched on, even at midnight (when traffic is almost zero on the road), and therefore the energy spent on the maintenance of the light on, though not required. If the project uses RTC, a key component for seasonal fluctuations, cannot be taken into account and task duties, that’s really a time to not fully fulfill. Given these technical issues, this project is designed to overcome the limits of the old system and save energy.

This system switches on the lights only at preprogrammed timings. As the DS1307 Real Time Clock chip with battery back-up is used, there will be no disturbances for the programmed on/off timings even in power failures. The project also works perfectly according to the seasonal weather conditions. This project uses Ldr to read the intensity of sunlight. Sensors read intensity values, convert to electric power signals and display it to the ADC. ADC converts analog to digital values ​​and transmits these data bits to the microcontroller. The microcontroller makes a decision according to the result of a sensor. So the light operation microcontroller, consider both RTC and LDR output.

The power is taken from the solar panel and is also stored in batteries that can be supplied to controllers and other devices.
