ldr (light depending resistor ) whose resistance is based upon the quantity of the light declining on it along with a few more components. circuit diagram of automatic street light controller switch circuit using relays and ldr is given below. automatic street light controller switch circuit electronicshub.org
1. introduction the solar led street lighting system uses the solar radiation energy to charge the battery with the solar panel during day time, and offer energy to the led light equipment at night. this system has a double advantage in both utilization of new energy and energy saving.

the project requires sensors to detect the vehicle movements and switches on the lights ahead of it. as soon as the vehicle moves ahead the trailing lights automatically switches off. this can be used to save a lot of energy instead of using conventional system where the street lights are remained on.
we can develop solar street light system with automatic street light controller. the system can be powered from a battery, which can be charged during day time by harvesting the solar energy through a solar cell. the solar energy harvested from sunlight can be stored, inverted from dc voltage to ac voltage using sun tie converter.
solar charge controller user s manual 8 12v, 24v, 48v are three common voltage type for dc solar power system, and the higher voltage type is, the larger power could be used. users have to select voltage type according to the power of the load, the work voltage range of the load and some other factors.
this section describes the details of the pv inverter control and software for the solar explorer kit. 6.1 project framework. as shown earlier, the pv inverter control requires two real time isr s one is for the closed loop control of the dc dc stage and the other for the closed loop control of the dc ac stage.
