Switching Circuit Design of an Automatic Fire Suppression System

A switching circuit helps the society with the elimination of any human hand to switch the electronic home appliances on or off between electronic components and systems thus improving efficiency and the possibility of shocks to human becomes very low. High power devices such as motors, solenoids or lamps, often require more power than that supplied by an ordinary logic gate, so transistor switches are used. Switching circuit designed such that it’s made of a transistor, protection diode and a resistor. An attempt is made to outline what appears to be the most promising method of obtaining beneficial results from the use of cheap components in the design of practical switching circuits. Switching circuit designed such that it made of a transistor BC 107/108B, protection diode (1N4001), and resistor (220Ω), LDR and a potentiometer.
