Intelligent Fire Detection system with automatic water sprinkler system using MSP430

Fire accidents can take place more in areas like houses, industries, Movie theaters, shopping malls, hospitals, etc., which will lead to more loss in life along with properties. Generally waiting for a fire engine to extinguish fire, may be delayed which may increase the chance of loss in life. There are so many preventive mechanisms have been developed to prevent/reduce the fire accidents to some extent. But always automatic solution brings more accuracy to protect lives from fire accidents.

In this project, an automatic fire detection and extinguish solution is implemented by using Embedded systems and sensor technology. This automatic solution will respond in time, when fire is detected and will save many lives by sprinkling the water on the fire. A smoke sensor is used to detect the fire occurred in the room and it will intimate to the control circuit via electrical signals. Now the control circuit will automatically drive the motor in the sprinkler and sprinkle the water on the fire. Generally this control circuit uses analog to digital converter to convert the analog output from the sensor into digital, processed and then finally drive the sprinkler system.

In this project, MSP430 microcontroller is used as a main controller for the control circuit of the system. The MSP430 itself contains inbuilt 10-bit ADC, so that, it will reduce the size and cost of the system. An uln2003 is used to drive the DC motor by allowing the motor current through, which is not allowed in the microcontroller. A gas/smoke detector sensor is used to detect fire and fed the information to the ADC which is available in MSP430 microcontroller. But actually here we used a gas sensor with digital output, so no need to program the ADC10 of MSP430. Directly the output of the Gas sensor is connected to the port pin of the MSP430 as an interrupt.

Important tasks:
1. Interfacing Gas sensor or fire sensor with MSP430.
2. Interfacing 16x2 LCD with MSP430.
3. Interfacing DC motor with MSP430 MCU using ULN2803.
