The CM1109 Dual IR Source NDIR CO2 Sensor is designed to measure CO2 for safety, beverage, agriculture, industrial or cold chain storage applications.
The advantage of a dual source, dual beam sensor is that over time it self-compensates for the influence of temperature and humidity, light source aging and other factors that impact the sensor's accuracy. This results in better stability over its lifetime.
Features
- Superior Stability & Accuracy
- Temperature and Humidity Compensation
- High Accuracy Supports WELL, RESET, ASHRAE 62.1-2019 Addendum aa & California Title 24 Application

CM1109 - Dual IR Source NDIR CO2 Sensor - designed for long-term stability.
-
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.
We recommend that all first time users purchase both this sensor and the CM-200 Development Kit for fastest and easiest results.
