The CM1106H-NS High Accuracy NDIR CO2 Sensor (CU-1106H-NS) is a single beam, low cost CO2 sensor designed for OEMs to hobbyists. The sensor uses non-dispersive infrared (NDIR) technology, which can detect CO2 concentration of indoor air. With high accuracy, high stability, and a small size it is widely used for ventilation systems, air purifiers, air conditioners, HVAC transmitters, and IAQ monitors. This sensor is designed to support WELL, RESET, ASHRAE 62.1 2019 Addendum aa & California Title 24 Applications. **Please Note: 6-8 week lead time** Features High accuracy and precise measurement NDIR sensor outputs either UART and PWM Maintenance free - Automatic Baseline Calibration (ABC) Temperature and humidity compensation throughout the entire measurement range Long life span (15+ years) Small, Compact structure, easy to install Applications Indoor Air Quality Ventilation Systems Air Purification HVAC Demand Control Ventilation Automotive Models CM1106H-NS: High Accuracy NDIR CO2 Sensor for OEMs or hobbyists Specifications Gas Type: CO2 (Carbon Dioxide) Operating Principle: Non-dispersive infrared (NDIR) CO2 Range: PWM (0-2,000 ppm), UART (0-10,000 ppm) CO2 Accuracy: ± (30ppm+3% of reading) @ -10°C~50°C ,0-85%RH, UART/PWM 0-2,000 ppm Response time: 30s 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) Sampling Frequency: 1s Time to First Reading: ≤30s Power Supply: DC4.5V-5.5V Ripple Wave:
