Arduino Project With Code || Fire Alarm Using Arduino

In this video i'm going to show you "How To Make Fire Alarm Using Arduino"
Creator: Hridoy Hridh

**Materials required:
1. An #Arduino with its Adapter
2. A Bread Board
3. A Thermistor (10K)
4. A Buzzer
5. 4 Male to male jumper wires
6. Resistor 10K
--Total Cost: About 750 BDT --
Hope this is helpful.

**Procedure:
The thermostat will be used as a fire sensor for fire alarm circuits. Thermistor is a registry that changes with the temperature of the Registry. Increasing the temperature may reduce the thermostat's resistance, may increase. As the temperature increases, PTC (Positive temperature coefficient) thermistor that increases the resistance of the thermistor and decreases the resistance to the increase in temperature, called NTC (Negative temperature coefficient) thermistor. The thermostat we use in this experiment is an NTC thermostat. That means, in the presence of fire, the thermostat's temperature will decrease if its temperature increases. And we know from Ohm's formula (V = IR) that decreasing the resistance means decreasing voltage. So, if we observe the change of this voltage through an analog pins of the Arduino, then we will understand the presence of the fire. In this series, a 10 kilo-haired fixed registry was installed in the series with the thermometer. Detected voltage of fixed registry and thermostat intersection is measured through A0 pins. Arduino analog pins will see the value of the serial monitor. During our experiment, this value was around 570 in room temperature. The value of the fire near the thermostat surface was reduced to below 500 and gradually decreasing. For alarms, we added a buzzer to the 10th pin of the Arduino. When the value of analog value is below 500, the buzzer will ring and people will be able to recognize the presence of the fire when they hear the sound.

will it be the same if i put a flame sensor?
