The safety of the workers is a major thing to be looked into before establishing an industry. This project aims at providing safety to the workers by raising alarms whenever there is a panic situation. This alerts people inside the industry and will save the lives of many from such dangerous situations.

LIGHT EMITTING DIODE
LIGHT EMITTING DIODE is a component/device commonly used in electronic circuits. Majorly it is used as a sign of indication where there is a need to check the transmission of data. As the name says the diode inside it emits light of a certain wavelength. The operating voltage varies from LED to LED. The one used in this project has an operating voltage of 1.8v approx. Operating voltage can be found out from the datasheet.
Piezo buzzer is an electronic device that produces a tone of the desired frequency. It consists of a piezoelectric substance( which produces mechanical stress on the application of voltage and vice versa) which produces the required sound. When voltage is applied the inner material expands and contracts to hit the outer material at a certain frequency thus resulting in the production of the desired tone.
