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. 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 CU-1106H-NS-DK Development Kit - Includes the CU-1106H-NS sensor plus a USB/FTDI cable to communicate with our free GasLab software. Sensor Development Kit (CM-200) - Easy to use, simply plug the sensor into the PCB and plug it into your PC via USB. Use our free GasLab® software to measure and graph carbon dioxide or use our library of source code on Github to build your own application or for OEM batch testing/configuration. Order sensors on this page, then order the Devkit here. Note: pinned sensors may require minor pin clipping. We recommend that all first time users purchase both this sensor and the CM-200 Development Kit for fastest and easiest results.
