CM1109 Dual-IR NDIR Carbon Dioxide Sensor

Description

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

Applications

• Indoor Air Quality (IAQ)
• HVAC controller
• Central Air Conditioning
• Agriculture

Models

• 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.
