Automatic Street Light control system using Timer IC- The Automatic street light control system is seriously an amazing project and no doubt this is one of my favorite projects. This is a very small project build around a few electronic components. In this project, you will learn how to make an automatic street light control system using timer IC and an LDR.

Automatic Street Light Controller Circuit Using Relay and LDR

Did you ever think that how the street lights automatically turn ON in the night and turn OFF automatically at morning? Many people have a phobia of darkness, so to assist them in such situations, we have explained a simple circuit that will automatically turn on the street light consisting of LEDs or bulb coupled with relay. It is lit well enough to see the objects nearby. This circuit is very easy to work around and also it is battery operated.

The power consumed by the circuit is very low because of the very few components used in the circuit. The whole circuit is based on IC LM, which is basically an operational amplifier that is configured in a voltage comparator. LDR Light depending resistor , whose resistance is based upon the quantity of the light falling on it, is the main component for sensing the light.

Along with these, a few more components are also used. Note: This circuit can also be built using microcontroller. To get an idea about the circuit built using microcontroller, read the post: Street Lights that Glow on Detecting Vehicle Movement. It is an Operational Amplifier IC. It is available ib 8-pin DIP Package and can be used in several configurations like Amplifier, oscillator, comparator etc.

LDR is a device whose sensitivity depends upon the intensity of light falling on it. When the strength of the light falling on LDR increases the LDR resistance decreases, while if the strength of the light falls on LDR is decreased, its resistance increased. In the time of darkness or when there is no light, the resistance of LDR is in the range of mega ohms, while in the presence of light or in brightness in decrease by few hundred ohms.

Before mounting any component in the circuit it is a good practice to check whether a component works properly or not so that you can avoid consumption of time in troubleshooting. For testing LDR set the range of multimeter in resistance measurement. Measure the resistance of LDR in the light or brightness and the resistance must be low. Now, cover the LDR properly so that no light falls on it and once again measure the resistance. It must be high. If you got the satisfactory result, then your LDR is good.

It is a passive component having two terminals that is used to manage the current flow in the circuit. A current that flows via a resistor is directly proportional to the voltage that appears across the resistor.

Resistors are of two types —. Value of resistance can be calculated with the help of multimeter or with the color code that is visible on the resistor. It provides isolation between the controller and the device because as we know devices may work on AC as well as on DC but they receive signals from microcontroller which works on DC hence we require a relay to bridge the gap. The relay is extremely useful when you need to control a large amount of current or voltage with the small electrical signal.

The working of circuit is very much easy to understand. Pins 2 and 3 of these IC are used to compare the voltage and give us an output as high or low depending on the voltages at the input pins. As we know the property of LDR that during the day time, its resistance is low, the voltage at the non-inverting input i.

Hence, the output at the pin 1 is high. But in dimness or at night time, we know that resistance of LDR is high. As a result, the output pin 1 moves to low state, which further makes the relay to activate and the LED or bulb associated to it will glow. By varying variable resistor, will I be able to control On and Off the light at required light intensity….

Please explain…. Hello, I have designed same circuit and it is working properly if power supply is on continuously, But when Relay is in ON condition and I Off and On the main power supply I cannot get relay in ON condition. What is the solution?

Please give me its solution to solve this problem. What is the contribution of transistor and capacitor in this automatic street light controller circuit??

PlZ send the circuit diagram of automatic street light using transformer ,bridge ntransistor BC, ldr , relay. Sir, how we will decide the values of resistors and capacitors? I want the design of automatic Street light using ldr design which gives the requirement of each components values. Your email address will not be published.

Comments Is it possible to use this setup without using a relay?? Can i still use 9 v battery to power the whole circuit using led. Hello, R2 is E. What is E? Best Regards Beyazit. Could you please tell me the voltage and wattage rating of lamp used in this project!!!!!!

Will u pls send me the same circuit using 2 transistor with 2 LDR n timer with relay?? Pls this automatic switch with relay, how do I power it? Because it is not indicated thanks. What is rating of relay. For example to watt lamp. Hi, By varying variable resistor, will I be able to control On and Off the light at required light intensity…. Can you please tell me the lamp you used in this project of howmany volts. Can u give mi the exact value of LDR which was used in this project.

What can be the maximum range of infrared sensor available in present scenario. Can I use LM or comperator. If i can do that then how is it works. Can i have whole circuit diagram along side with pdf plz. Would it be possible to set up 5 individual LEDs instead of the led strip?

Pcb Layout For Automatic Street Light

Did you ever think that how the street lights automatically turn ON in the night and turn OFF automatically at morning? Many people have a phobia of darkness, so to assist them in such situations, we have explained a simple circuit that will automatically turn on the street light consisting of LEDs or bulb coupled with relay. It is lit well enough to see the objects nearby. This circuit is very easy to work around and also it is battery operated.

We have designed a system where there is automatic turning on and off of the light whenever required. When darkness is detected then the sensor circuit gets activated and switches ON automatically and when there is other source of light during daytime, the street light gets OFF. Also this circuit can be used to adjust the sensitiveness of the light. The circuit is cheap and economic and can be made easily. On large scale the circuit can be used with solar cell as energy source and big light source can be used at night and instead of manual operation automatic operation can be implemented.
