Web1 de fev. de 2024 · In this work, a simple CO 2 gas sensor was built based on measurements of the thermal conductivity of CO 2 gas in N 2 and CO 2 gas mixtures using a thermopile IR sensor. The sensor has several advantages, including cheaper production costs, less energy required and ease of manufacture. In general, thermopile sensors are … WebThe sensor operates through the following method: An infrared light emitting diode (IR LED) emits light at a wavelength of 4.26 um. The IR light passes through the air and hits CO2 molecules which absorb that specific wavelength of light.
