CO2 gas sensor CM1109

NDIRinfraredfor air quality monitoring

Cubic patented two-engine CO2 sensor CM1109 is used to detect CO2 concentration of indoor air by adopting infrared (NDIR) technology. With higher accuracy and better stability, it is widely used for ventilation system, air purifier, air conditioner, intelligent agriculture, storage and cold-chain, etc. Features Dual IR source NDIR technology with independent intellectual property High accuracy, long term stability, long lifespan(＞15 years) Matrix calibration within whole measurement range and temperature range Small size and compact structure, easy to install Signal output PWM/UART/ I²C Applications ▪ Greenhouse facilities ▪ IAQ monitor ▪ Intelligent agriculture ▪ Air purifier ▪ Cold-chain ▪ Portable instruments ▪ Automotive Specifications ▪ Measurement range 0~5000ppm default（0~10000ppm could be customized） ▪ Response time ≤30s ▪ Accuracy ±(50ppm+3% of reading) 0-2000ppm, 0-50 ℃, 50±10%RH ▪ Working temperature -10℃~50℃ ▪ Working humidity 0~95% RH（non-condensing） ▪ Power supply DC3.5V-5.5V; Ripple wave ＜50mV ▪ Working current Average＜45mA ▪ Signal output UART_TTL, PWM, I²C ▪ Dimension W33*H8.7*D19.7（mm） * The above features and specifications are preliminary version.
