Just imagine when an apartment is caught fire in the second floor! The people in the second floor can easily recognize the fire and can inform to their neighbors and run for their lives; but people in the first, third and fourth floors may not know the fire accident and busy with their work. This will be great danger to the people live and property also. So there should be an alarm to inform to all people in the apartment in which the fire has taken place and act immediately. Here fire alarm plays a key and important role. It will detect the fire automatically and inform to the people with an alarm. Now-a-days, fire alarms are must for the apartments, theaters, hotels, restaurants, coal mines, petrol bunks or gas stations, etc.Here are two simple fire alarm circuits which will use different concepts and different components for generating the fire alarm. The main basic concept is almost same that sensing the fire or heat by the component and giving that information to the remaining circuit to give alarm. In this fire alarm circuit project, a thermistor works as the heat sensor. When temperature increases, its resistance decreases, and vice versa. At normal temperature, the resistance of the thermistor (TH1) is approximately 10 kilo-ohms, which reduces to a few ohms as the temperature ncreases beyond 100°C. The circuit uses readily available components and can be easily constructed on any general purpose PCB. Check out the fire sensor complete circuit project. 100% Work
