These types of sensors are used for short range fire detection and can be used to monitor projects or as a safety precaution to cut devices off / on. This Flame Sensor module is accurate up to about 3 feet. The flame sensor is very 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 certain threshold, the output high and low signal threshold adjustable via potentiometer.
VCC – Positive voltage input: 5v for analog 3.3v for Digital.
A0 – Analog output
D0 – Digital output
GND – Ground
To connect the Flame Sensor to the Arduino connect the following as shown in the above Diagram:
