INTELLIGENT FIRE DETECTION SYSTEM WITH AUTOMATIC SPRINKLER WATER SYSTEM USING MSP430
Fire accidents can take place more in areas like homes, industries, movie theatres, shopping centres, hospitals, etc., which will lead to more losses in life along with properties. In general, hoping that a fire engine to put out the fire, can be delayed, which can increase the probability of loss in life. There are so many preventive mechanisms that have been developed to prevent / reduce fire accidents to some extent. But the automatic solution always brings more precision to protect lives from fire accidents.
In this project, an automatic fire detection and extinguishing solution is implemented using embedded systems and sensor technology. This automatic solution will respond in time, when a fire is detected and you will save many lives by spraying the water in the fire. A smoke sensor is used to detect the fire occurring in the room and will be close to the control circuit via electrical signals. The control circuit will now automatically drive the motor into the sprayer and spray the water into the fire. In general, this control circuit uses analog-to-digital converter to convert the analog output of the sensor into digital, processed and finally drive the sprinkler system.
The MSP430 micro-controller is used as a main controller for the system control circuit. The MSP430 itself contains built-in 10-bit ADC, so it will reduce the size and cost of the system. An uln2003 is used to power the DC motor by allowing motor current through, which is not allowed in the micro-controller. A gas detector / smoke detector is used to detect fire and power information to the ADC that is available on the MSP430 micro-controller. But in reality here we have used a gas sensor with digital output, so there is no need to program the MSC430 ADC10. Directly the gas sensor output connects to the MSP430 port pin as an interrupt.
Important tasks:
1. Interface Gas sensor or fire sensor with MSP430.
2. 16x2 LCD interface with MSP430.
3. DC motor interface with MSP430 MCU using ULN2803.
