The article proposes an optoelectronic two-wave method for monitoring the methane content in the atmosphere. Spectral characteristics are given two-color LED module LED39, LED32, photodiode PD36 and methane absorption spectrum. An optoelectronic sensor for monitoring the methane content in the atmosphere with high measurement accuracy has been developed, and its block diagram is shown. In an optoelectronic sensor for monitoring methane content in the atmosphere A two-color LED module with emission spectra of 3.2 microns (reference) and LEDs with emission spectra of 3.4 microns (working) were used . To increase the optical power of LEDs (3.2 and 3.4 microns), a design with more efficient heat removal and a parabolic reflector design for LEDs, which focuses IR radiation at an angle of 8-10 degrees, have been proposed. LED crystals with emission spectra of 3.2 microns and 3.4 microns are mounted in one housing to ensure high accuracy and sensitivity of the device.
