How Flame Sensor Works

These sorts of sensors are used for brief range fire detection and may be wont to monitor projects or as a security precaution to chop devices off / on.

The flame sensor is extremely sensitive to IR wavelength at 760 nm ~ 1100 nm light.

Analog output (A0) : Real-time output voltage signal on the thermal resistance.

Digital output (D0) : When the temperature reaches a particular threshold, the output high and low signal threshold adjustable via potentiometer.

Pins :

  • VCC    —  Positive voltage input: 5v for analog 3.3v for Digital.
  • A0      —  Analog output
  • D0      —  Digital output
  • GND  —  Ground
