CO2 sensor CM1106H-NS

NDIRinfraredfor air quality monitoring

High accuracy with ±（30ppm+3% of reading) CO2 sensor CM1106H-NS can be used to detect CO2 concentration of indoor air by adopting advanced non-dispersive infrared technology (NDIR). With auto-calibration, no need of maintaince. It is widely used in ventilation system, air conditioner, air purifier, IAQ monitor, agriculture, plant cultivation and cold-chain, etc. Features ▪ NDIR technology with independent intellectual property ▪ Temperature calibration within whole measurement range ▪ Long life span, auto-calibration, maintenance free ▪ Small size and compact structure, easy to install Applications ▪ HVAC industry ▪ IAQ monitor ▪ Air purifier ▪ Automotive ▪ IoT devices ▪ Plant growth Specification Measurement range PWM: 0-2000ppm UART0-10000ppm (Note 1) Working temperature -10°C ~ 50°C Working humidity 0-95%RH (non-condensing) Storage temperature -30°C ~ 70°C Storage humidity 0-95%RH (non-condensing) Accuracy ± (30ppm+3% of reading) @ -10°C -50°C ,0-85%RH (Note 2 and 3) Sampling frequency 1s Time to first reading T90 < 30s Power supply DC 3.5V~5.5V Ripple wave <50mV Working current <50mA Dimensions 33x19.7x8.9mm (pin is not included) Weight 5g Signal output UART_TTL;PWM liner output Life span ≥15 years Maintenance Maintenance-free for normal indoor application with Auto-calibration
