Arduino Flame Sensor Interfacing to Build a Fire Alarm System

02/08/2018· The flame sensor detects the presence of fire or flame based on the Infrared (IR) wavelength emitted by the flame. It gives logic 1 as output if a flame is detected, otherwise, it gives logic 0 as output. Arduino Uno checks the logic level on the output pin of the sensor and performs further tasks such as activating the buzzer and LED, sending an alert message.

Fire Fighting Robot Using Arduino

to sense fire we use the fire sensor (Temp sensor) that is shown below which is used to detect the fire. the output pin (DO) will give 0V(LOW) and if the is no fire the output pin will be 5V(HIGH). So, we place three such sensors in three directions of the robot to sense on which direction the fire is burning. We detect the direction of the fire we can use the motors to move near the fire by ...

What are the three pins of an infrared sensor? - Quora

When the supply is given to IR sensor, LED starts emitting light radiations. If the surface is of white color then it reflects all the radiations. As these radiations starts falling on the photodiode which is connected in reverse bias, the resistance of the photodiode starts decreasing rapidly and the voltage drop across the diode also decreases. The voltage at Pin 3 starts increases, as it reaches just beyond the voltage of Pin …

pwm - How to interpret the output of a 3-pin computer fan ...

The sensor is amplified, and eventually drives a logic circuit. The fans that I have seen use an open drain/open collector output. One (or more) pulse is generated every time the the fan rotor completes a revolution. The number of pulses counted in one minute is directly proportional to the RPM of the fan. In your fan's case, I think it would be reasonable to guess that there are two pulses ...
