Automatic street light controller

In a high-voltage circuit, attention must sometimes be paid to the rated maximum working voltage of the resistor.

The project shown in Fig. For example, you are too much lazy to turn on or turn off your street light manually and you forget to turn it on or off daily.

It is a passive component having two terminals that are used to manage the current flow in the circuit. System Scheduler — enables programmed scheduling of dimming levels for Automatic street light controller luminaire and groups of luminairs.

In this process free electrons from the n side will diffuse spread into the p side and combine with holes present there, leaving a positive immobile not moveable ion in the n side.

For example, you are too much lazy to turn on or turn off your street light manually and you forget to turn it on or off daily. LDR is a device whose sensitivity depends upon the intensity of light falling on it. There are different types of connectors, In this project we used few of them. When the light falling occur means resistance value will be change.

Saving power is very important, instead of using the power in unnecessary times it should be switched off. With this microcontroller based project, the manual operation of the lighting system is eliminated completely.

LDR have property to change its resistance according to intensity of light. Low-pressure sodium lamp s became commonplace after World War II for their low power consumption and long life. So you easily use this project to save your electricity and in return your money.

Automatic Street Light: Microcontroller based Mini Project & Idea

Microcontrollers are designed for small or dedicated applications. Oncoming headlights are more visible against a black background than a grey one. IC voltage regulator. Automatic light control is a simple yet powerful concept, which uses transistor as a switch. The IC was designed in by Hans R.

This is usually achieved with bright lights placed on high poles at close regular intervals so that there is consistent light along the route. The basic construction and symbol for LDR are shown in above figures respectively.

Nowadays, human has become too busy, and is unable to find time even to switch the lights wherever not necessary. The output comes from PB1 15 no. Hence few atoms on the p side are converted into negative ions. If there is a sharp curve where headlights will not illuminate the road, a light on the outside of the curve is often justified.

This paper gives the best solution for electrical power wastage. These have two pairs of terminals. Hence, such will be a rippled DC voltage.

Automatic Street Light Controller Circuit Using Relays and LDR

In this project the first thing to do, is to prepare the inputs and outputs of the system to control the lights. Due to its versatility, availability, and low cost it remains a hobbyist The connection of the pins for a DIP package is as follows: On Interstate highways this purpose is commonly served by placing reflectors at the sides of the road.

In this part 12V DC power supply connected with a relay. In practical usage, these lights are needed only between 6: Applications include falling edge sensitive instead of level sensitive.Here is our new simple Electrical/Electronics project about Automatic Street Light Control System for students and hobbyists.

It is a simple and powerful concept, which uses transistor (BC NPN) as a switch to switch ON and OFF the street light system automatically. It automatically switches ON. The Automatic street light controller unit fabrication is cost-effective with good sensitivity and high reproducibility.

The circuit is designed in such a way that the extent of darkness at which the light has to switch ON or OFF also can be tailored whenever it is needed. balcony lighting etc. five different level of street light brightness has been used for lighting up the street and proportional to the number of traffic.

The system was programmed to automatically turn off during the hours of daylight and only operate during the night and heavy. Automatic Street Light Control System is a simple and powerful concept, which uses transistor as a switch to switch ON and OFF the street light automatically.

By using this system manual works are removed. It automatically switches ON lights when the sunlight goes below the visible region of our.
