This project is an innovative solution to control LED street lights for a specific duration on any specific time. It gets switched off automatically after exact duration. Real Time Clock maintains date and time. This is achieved by using the Atmega 328 MCU (Arduino UNO) . We can program microcontroller for desired time slots. The 16×2 LCD is connected to the microcontroller to display the status of the circuit. We are using Xbee Transmitter to transmit data to remote end. The data is received using Xbee Receiver. The wireless range can be upto 100m-300m in open space. The data is given to receiver side arduino UNO which controls LED lights. We are using current amplifier IC ULN2003 to drive four channels of high intensity SMD LED Lights. We can schedule four LED lights individually for any required timings using RTC (Real Time Clock).
We are using solar panel 12V 5 W to charge rechargeable battery 12V 1.3 Ah. We are also using charge controller circuit to limit the voltage for battery charging. Thus we can avoid damage to battery because of overcharging.
