Flame Sensor

Flame sensor is the most sensitive to ordinary light that is why its reaction is generally used as flame alarm purposes. This module can detect flame or wavelength in 760 nm to 1100 nm range of light source.

The sensor and flame should keep a certain distance to avoid high temperature damage to the sensor.If the flame is bigger, 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 digital or analog signal. It can be used as a flame alarm or in fire fighting robots.

It works by detecting infrared radiation emitted from fire. The detector detects this radiation and converts it into analog and digital signals for the microcontroller to process.

Note: Since flame sensor works on the principle of infrared detection, any other infrared source like your remote control, or any other source can trigger the sensor.
