A Flame sensor is the most sensitive to the ordinary light that is why its reaction is generally used as flame alarm purposes. This module can detect the flame or wavelength in 760 nm to 1100 nm range of light source.
The sensor and flame should keep a certain distance to avoid the high-temperature damage to the sensor. If the flame is bigger, then test it with farther distance. The detection distance is up to 100 cm. The detection angle is 60 degrees so the flame spectrum is especially sensitive. Its output is a digital or analog signal. It can be used as a flame alarm or in the fire fighting robots.
It works by detecting infrared radiation emitted from the fire. The detector detects this radiation and converts it into the analog and digital signals for the microcontroller to process.
