When a bus is moving on a highway, suppose there is a short circuit, fire breaks out, passengers get frightened, and the driver cannot take the bus to the side and stop immediately. By that time, fire damage has already started which will panic the commuters. To avoid this, the idea of a water spray mechanism is developed.
Fire Alarm Circuit is a simple circuit that detects the fire and activates the Siren Sound or Buzzer. Fire Alarm Circuits are very important devices to detect fire at the right time and prevent any damage to people or property. Fire Alarm Circuits and Smoke Sensors are a part of the security systems which help in detecting or preventing damage. Installing Fire Alarm Systems and Smoke Sensors in commercial buildings like offices, movie theatres, shopping malls and other public places is compulsory. There are many expensive and sophisticated Fire Alarm Circuit in the form of stand-alone devices, but we have designed very simple Fire Alarm Circuits using common components like Arduino UNO, Bread board, Fire sensor, Jumper wire, LED’s, Buzzer, Relay Module, Battery.
The primary purpose of the fire alarm system is to provide an early warning of fire so that people can be evacuated & immediate action can be taken to stop or eliminate the fire effect as soon as possible.
