LFG201 Wall-mounted Carbon Dioxide Transmitter is based on the fact that different gases have different absorption capabilities for infrared light in a specific band. It measures the concentration of the measured gas by measuring the degree of infrared light absorption. Compared with electrochemical sensors, it has the characteristics of long life and good stability, wide power supply range and power supply anti-reverse connection protection. It is suitable for indoor air quality detection, air conditioners, air purifiers, vegetable greenhouses and other occasions to measure carbon dioxide gas.

  • Imported infrared light source and dual-channel thermopile detector.

  • The sensor is oxygen-free and has a service life of >5 years.

  • Long-term stability and reliability.

  • Double-layer waterproof membrane design effectively prevents water vapor from entering.
