The project titled "Design and Implementation of Automated Thunderbolt Protector Using Light Sensor" submitted by Moriumnasa Mim (CSE Tasnimul Hasan (CSE Naima Akter Moon (CSE Md.Emamul Haque Munna (CSE) and Md.Zihad Hossain (CSE to the Department of Computer Science) and Engineering, Sonargaon University (SU), has been accepted as satisfactory for partial fulfillment of the requirements for the degree of Bachelor of Science in Computer Science and Engineering and approved for style and content. We hereby certify that the work presented in this report is the result of the research conducted by us under the supervision of Salma Tabashum, Lecturer, Department of Computer Science and Engineering, Sonargaon University, Dhaka, Bangladesh. For this reason, we face many problems such as the death of people until thunder.
As a result of lightning, various electronic devices in houses, offices, and shops were also destroyed. So we tried to create a smart multi-purpose plug that will solve our problem related to lightning. When it rains, we forget to turn off our electronic devices, so the device is destroyed by lightning.
At the very beginning, we would like to express my deepest gratitude to Almighty Allah for giving us the ability and strength to successfully complete the task within the scheduled time. We are blessed to have had the kind dealings and supervision of Salma Tabashum, Lecturer, Department of Computer Science and Engineering, Sonargaon University, whose warm and valuable support, with the utmost care and guidance, acted as a necessary refuge to carry out our project. Dr. Md Alamgir Hossain, Dean, Faculty of Science & Engineering and special thanks to our esteemed Head of Department Bulbul Ahamed, Associate Professor and Head, Department of Computer Science and Engineering for their kind concern, discretion, kind behavior and valuable suggestions.
We are also grateful to all our teachers throughout our education for exposing us to the beauty of learning.

How many degrees is the temperature of Thunderbolt usually?
Logic Gate ICs: Combinational circuit generates logic output based on a series of input signals. So ideally, almost all the primary winding flux should be connected to the secondary winding. It is possible to buy a resistor of any ohmic value you need, however in the vast majority of cases, it is possible to 'wire' the circuit to change the value required.
The only difference between the NPN and PNP transistor is in the direction of the current. Emitter – The part that provides the major portion of the majority charge carrier is called emitter. Page | 16 Collector – The section that collects the major portion of the majority charge carrier supplied by the emitter is called a collector.
Our smart multiplug will turn on after 3 minutes when the lamp light first falls on the internal sensor of the multiplug. Input part: As soon as the Smart Multiplug cable is connected to the power supply, the output part will not turn on.

Integrated Circuits Feature
Due to the small size and delicate nature of the IC, a series of small gold and aluminum wires are connected and molded into a flat block of plastic or ceramic. Size of an IC: The size of the integrated chip varies between 1 square mm to more than 200 mm. Integration of an IC: Because they combine different devices on a chip, integrated chips get their name.

What is Transformer?
The purpose of the transformer core is to provide a low reluctance path through which the maximum amount of flux produced by the primary winding is passed and connected to the secondary winding. This winding also winds on the same core and gives the desired output from the transformer. Often several resistors of the same value are required, for example in data bus pull-up applications.
But the tolerance or variation of the value of a resistor is affected by several parameters, as explained below. This is a measure of the variation of the nominal value due to temperature changes. This is mainly important if the design means that the resistor runs at or close to its maximum value and can significantly affect the long-term reliability of the system.
Unfortunately, things can be more complicated than that; for accurate work, the engineer must consider the temperature derating curve for the resistor. In addition, there is another type of resistor noise called current noise, which is caused by the flow of electrons in the devices. The exact shape of the output—that is, how long it's high and how long it's low—depends on the connections to the remaining five pins.
The trigger is an active low trigger, which means that the timer starts when the voltage on pin 2 drops below a third of the supply voltage. When this voltage reaches two-thirds of the supply voltage (Vcc), the timing cycle ends and the output on pin 3 goes low. The purpose of the capacitor is to smooth out any fluctuations in the supply voltage that may affect the operation of the timer.).
The collector portion of the transistor is moderately doped, but larger so that it can collect most of the charge carrier supplied by the emitter. The base of the transistor is lightly doped and very thin, providing most of the charge carriers at the base. The base of the transistor is very thin and lightly doped, so it contains fewer electrons than the emitter.
The few electrons from the emitter are combined with the hole from the base region and the remaining electrons are moved to the collector region and form the collector current. The two ends of the coil are connected to two pins of the relay as shown.
Introduction
Ambient Light
Light Angle and Direction
Measuring Light Intensity
Categories of Light
Reflected: Reflected light is light that comes from a light source and bounces off a distant surface and reflects on an object. Diffused: Diffused light passes through a distant diffusion device or material before reaching the subject. Radiant: A radiant light is a light source that enters a lens directly, such as flare, or a silhouette created by a backlight.
Light Sensors
Photoresistor
As the name suggests, photo resistors work similarly to normal resistors, but the change in resistance depends on the amount of light it is exposed to. High light intensity will cause less resistance between the cadmium sulfide cells, and low light intensity will cause more resistance between the cadmium sulfide cells. This principle of operation can be seen in applications such as street lamps, where the high intensity of light during the day results in a lower resistance and therefore they do not shine when the sun is still shining brightly.

Output section: To turn on the output section of the device, turn on the torch light on the indoor sensor. Thunderbolt protection method: Our smart multi-plug automatically turns off when the lightning from the lightning strikes the outdoor sensor of our smart multi-plug. Again, to turn on our smart multi-plug, we need to turn on the torch light on the indoor sensor.
The flashlight must be used repeatedly to turn the device on and off. If the device is turned off after the lightning strike, the device will not restart automatically. Our Smart Multiplug's outdoor sensor will automatically shut down the plugged-in device when it detects lightning from thunder.
