An automated fire suppression mechanism controlled using an Arduino

Abstract

The proposed fire suppression system is a real time monitoring system that detects the presence of flame of certain wavelength in the air due to fire and suppresses the fire via continuous water running through multiple sprinklers. The controlling unit used to develop the fire alarm system is an Arduino Uno. The key feature of this system is the ability to remotely send an alert when a fire is detected. Fire is an undesirable event that could cause a great loss of social wealth, human life and confidential amenities. To prevent these losses, various alarm systems have already been developed such as smoke detectors, temperature sensor based systems etc. These systems comes with a high chance of human error that can mislead the sensing and hence the whole system in general. Our fire suppression system on the other hand is extremely well thought out; it has no chance of human error as it is fully self-sufficient. The room or the area will have dedicated overhead sprinklers connected to the water supply through its dedicated solenoid valve which controls the flow of water in the pipe lines. The triggering devices of this system are the flame sensors, when they detect fire an alarm will go off. The coding set in the Arduino will come into work and provide the optimal voltage to the solenoid valve through a relay and hence water will rush out the sprinklers extinguishing fire in no time. The sensors we will be using are highly sensitive, thus it will detect fire even before it reaches to a point of concern. Water will be evenly spread out through the overhead sprinklers. Unlike other alarm systems, the components we used are readily available and reasonable in price. Our automated fire suppression system can be used both for commercial and residential purposes.
