Detail

The dual-beam carbon dioxide (CO2) gas sensor has three major characteristics: high long-term stability (dual-beam reference optical design), ultra-low noise (RMS noise less than 1.0 ppm), and a long service life of over 15 years. It is especially suitable for indoor air quality monitoring, HVAC and fresh air systems, automotive cabin air monitoring, and agricultural greenhouse monitoring to achieve precise and long-term stable CO2 concentration detection. Different measurement ranges (such as 400 to 2,000 ppm, 400 to 5,000 ppm, or 400 to 10,000 ppm) and output interfaces (UART, PWM, I2C) can be customized according to customer requirements. Form factors and output modes are customizable; please contact our company for more application details.
