Light Sensitive Automatic On Off Light:
This diagram Shows An Occupancy Sensor Automatically Turns the light ON and OFF. Great for areas where lights are accidentally left on a lot, like in a kid's room, or where Your hands are full, Like in a Laundry area. When motion is detected, the Sensor Triggers the Light. When the Motion Stops Being Detected.

Components used to make theLight Sensitive Automatic On Off Light:
01. BT 136 Transistor
 |
| Fig 2:Â BT 136 Transistor |
Transistor is a semiconductor device, which is commonly used as an amplifier and electrically controlled switch. Transistors are 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 two diodes together. For example, if you know that a diode has a p-n junction, adding another p to it will make a p-n-p transistor. It is nothing more than an initial idea. Currently, transistors are not made this way. Transistors are made in a more advanced way.
02. LDR Resistor
 |
| Fig 3:Â LDR Resistor |
The main function of a resistor is to block the flow of current or cause a voltage drop in an electronic circuit. In short, the function of the register is to prevent the movement of electricity. When we know about electronics, the first name that comes is Resistor. It is basically a common component of electronics. This component is used in every electronic circuit. A resistor is a very familiar component to those who work with electronics. It has a special function. Resistance is denoted by R. Its unit is the ohm (Ω). The following figure shows some resistor symbols that are used in various circuit boards and circuit diagrams.
03. Adjustment Variable
 |
| Fig 4:Â Adjustment Variable |
A Variable Resistor is a Type of Resistor Whose Electrical Resistance Value Can be Adjusted On Demand. Variable Resistors are Used in An Electronic Circuit to Adjust Circuit Resistance as a Means to Control The Voltage or Current Within a Circuit. The electrical resistance is Varied by Sliding a Wiper contact Along a Resistance Track. Sometimes the Resistance is Adjusted at a Preset value as Required at the Time of the Circuit Building by Adjusting the Screw Attached to it and Sometimes Resistance can be Adjusted When Required by Controlling The Knob Connected to it.
04. DIAC DB3
 |
| Fig 5: DIAC DB3 |
Diode conducts current only after its breaks over voltage. When a breakdown occurs, the diode enters the negative dynamic resistance region. As a result, the potential drop across the diode decreases and usually the current in the diode increases sharply. Below this value, the diode returns high resistance and is in a non-conducting state. Most discs have a three-layer configuration with a break-over voltage of around 30 volts. The disc has no gate edge, so it is different from other thyristors, which typically use a trigger.
05. 100K Resistor

06. Bulb

| Fig 7:Â Bulb |
CFLs work in a completely different way from ordinary lamps, they work by using a different process called fluorescence rather than generating light from heat. A typical light bulb wastes 90% of energy and converts only 10% of energy into light, this is where CFL has the biggest advantage. CFL- Curved or conical glass tube filled with argon and a small amount of mercury vapor. The inner wall of the glass is coated with fluorescent material. CFL- It is manufactured using the principle of creating fluorescent light. CFL- Originally white in color but now the construction and use of CFLs producing colored light has become popular.
