Intelligent Fire Detection system

Idea 1
Fire mischances can happen more in territories like houses, businesses, Movie theaters, shopping centers, doctor's facilities, and so on., which will prompt to more misfortune in life alongside properties. For the most part sitting tight for a fire motor to stifle fire, might be deferred which may expand the possibility of misfortune in life. There are such a variety of preventive instruments have been created to forestall/decrease the fire mischances to some degree. Yet, constantly programmed arrangement conveys more precision to shield lives from flame mishaps.




In this venture, a programmed fire discovery and quench arrangement is actualized by utilizing Embedded frameworks and sensor innovation. This programmed arrangement will react in time, when fire is identified and will spare many lives by sprinkling the water on the fire. A smoke sensor is utilized to distinguish the fire happened in the room and it will close to the control circuit by means of electrical signs. Presently the control circuit will consequently drive the engine in the sprinkler and sprinkle the water on the fire. For the most part this control circuit utilizes simple to computerized converter to change over the simple yield from the sensor into advanced, handled and afterward at last drive the sprinkler framework.


In this venture, MSP430 microcontroller is utilized as a primary controller for the control circuit of the framework. The MSP430 itself contains inbuilt 10-bit ADC, so that, it will diminish the size and cost of the framework. A uln2003 is utilized to drive the DC engine by permitting the engine current through, which is not permitted in the microcontroller. A gas/smoke locator sensor is utilized to identify fire and nourished the data to the ADC which is accessible in MSP430 microcontroller. Be that as it may, really here we utilized a gas sensor with advanced yield, so no compelling reason to program the ADC10 of MSP430. Specifically the yield of the Gas sensor is associated with the port stick of the MSP430 as an interfere.

Idea 2
Security is essential concern all around and for each one. Each individual needs his home, industry and so on to be secured. This venture depicts a security alert framework that can screen an industry and home. This is a basic and valuable security framework and simple to introduce. This fire/smoke locator is acknowledged utilizing promptly accessible, minimal effort segments. One of its numerous applications is in any workplaces and shops for security against flame. The finder will detect smoke brought about by flame mischance and switch on the water sprinkler to avert real harm.

This framework detects the smoke. The smoke locator contains an IR transmitter and an IR collector. In the event that smoke is introduced between these two gadgets, the yield of the sensor goes high and actuates the sensor.

A transfer is associated with the framework and this hand-off is actuated when the smoke is distinguished. This hand-off switches on the water sprinkler.


The circuit works off a 5V battery or 5V managed control supply and uses smoke finder as its important segment. At first, when the power is exchanged on, decade counter is reset by power-on-reset parts. Subsequently, yield of Decade counter goes high and the whole circuit is out of gear state. Driven shows the power status. In case of smoke, decade counter is timed by the beats from the piezo fired component associated with its clock stick. Every one of the yields of decade counter are encouraged to hand-off driver exchanging transistor through diodes associated in OR mode. Promptly in the wake of timing, any of the yields of decade counter would go high and NPN transistor would direct. 

Therefore, SCR is terminated through its entryway. This, thus, empowers transfer. The hand-off contacts can be utilized to switch any water sprinkler gadget to avert significant harm brought on by flame. The circuit can be reset by immediately squeezing switch. Two Zener diodes at the clock contribution of IC1 are utilized for assurance against high voltage input. On account of rehashed false activating of decade counter, include a 100nF capacitor in parallel to the piezoceramic component.
