These
types of sensors are used for short range fire detection and can be
used to design DIY monitoring projects using an Arduino or Raspberry Pi.
It can also be used as a safety precaution to cut devices Off / On. The
device functions most accurately up to about 3 feet. This flame
sensor module is very sensitive to IR wavelength at 760 nm ~ 1100 nm
light. Detection angle of this module is about 60 degrees, the flame
spectrum is very sensitive.
Pins:
Analog output (A0): Real-time output voltage signal on the thermal resistance.
Digital output (D0): When the temperature reaches a certain threshold, the output high and low signal threshold adjustable via a potentiometer.
Indicator light: the green one for a switch, the red one for power an built-in potentiometer to control sensitivity.
