Bring a flame closer to the sensor and open the Serial moniter and if there's a flame detected the Serial moniter will print "FLAME FLAME FLAME" and if there's no flame it will print "NO FLAME

A flame sensor module that consists of a flame sensor (IR receiver), resistor, capacitor, potentiometer, and comparator LM393 in an integrated circuit. It can detect infrared light with a wavelength ranging from 700nm to 1000nm.The far-infrared flame probe converts the light detected in the form of infrared light into current changes. Sensitivity is adjusted through the onboard variable resistor with a detection angle of 60 degrees.

Working voltage is between 3.3v and 5.2v DC, with a digital output to indicate the presence of a signal. Sensing is conditioned by an LM393 comparator.

EXPANDED TECHNICAL DETAILS

High-Sensitivity Fire Detection

A foundational safety project that provides real-time monitoring of infrared radiation to detect open flames in home or lab environments.

  • IR Spectral Analysis: Interfaces with a specialized IR flame sensor that is tuned to the 760nm - 1100nm wavelength range produced by fire. The Arduino captures the analog voltage drop caused by the IR photons.
  • Variable-Alert Logic Matrix: Categorizes the flame intensity into "Distant," "Moderate," and "Critical." The firmware triggers different buzzer frequencies and LED patterns based on the calculated distance of the fire.

Hardware Hub

  • Latching Emergency Reset: Features a software latch; once a critial flame is detected, the alarm remains active until a physical reset button is pressed, ensuring no fire event is missed.
