Light Sensitive Auto On Off Light:
This photo shows an occupancy sensor that turns the light on and off automatically. Great for places where a lot of light is accidentally thrown in, like a kid's room, or you have your hands full, like in the laundry area. When motion is detected, the sensor triggers the light. When motion stops being detected.

Materials used to make theLight Sensitive Automatic On Off Light:
01. Bulb
CFLs work completely differently than normal bulbs, they work by using a different process called fluorescence instead of generating light from heat. A typical light bulb dissipates 90% of energy and converts only 10% of energy into light, this is where CFLs have their biggest advantage. CFL- Curved or conical glass tube filled with argon and a small amount of mercury vapor. The middle wall of the glass is coated with fluorescent material. CFL- It is manufactured following the principles of fluorescent lighting. CFL - Originally white in color, but now the construction and use of CFLs has become popular to produce colored light.2. 100K Resisitor
The main function of a resistor is to block current flow or drop voltage in an electronic circuit. In a word, the function of a resistor is to prevent the flow of electricity. When we know about electronics, the first name that comes up is resistor system. It is a common component of electronics. This material is used in every electronic circuit. A resistor is a very familiar element to those who work with electronics. It has a special function. Resistor is denoted by R. whose unit is ohm (Ω). The figure below shows some resistor symbols that are used on various circuit boards and circuit diagrams.
3. DIAC DB3
Diode normally conducts current after its overvoltage break. When a breakdown occurs, the diode enters a negative dynamic resistance region. As a result, the potential drop across the diode is reduced. Normally, the current in the diode increases sharply. Below this value, the diode offers high resistance and is in a non-conducting state. Most disks have a three-layer configuration with a break-over voltage of about 30 volts. The disc has no gate or edge, so it is completely different from other thyristors, which usually use a trigger.
4. Adjustment Variable
A variable resistor is a type of resistor whose electrical resistance can be adjusted according to value and demand. A variable resistor is used in an electronic circuit to adjust the circuit resistance as a means of controlling the voltage or current in a circuit. Electrical resistance is varied by sliding a wiper contact along a resistance track. Sometimes the resistance is adjusted as needed during circuit building by the screw attached to it and sometimes the resistance can be adjusted as needed by adjusting the knob attached to it.

6.BT 136 Transistor
A transistor is a semiconductor device, commonly used as an amplifier and electrically controlled switch. Transistors are commonly used as basic building blocks in computers, cellular phones and all other modern electronics. In terms of the structure of the electronic transistor, the transistor is made by combining 2 diodes. For example, you know that a diode has a p-n junction, then adding another p to it will make a p-n-p transistor. This is a basic concept. Today, transistors are not usually made this way. They are made in a more advanced way.
