Low Cost IR CO2 Sensors

Nondispersive infrared carbon dioxide sensors have been around for decades, but because of complex manufacturing they have always been more expensive than electrochemical CO2 sensors. That’s why we were excited to discover a line of sensors made by Cubic Optoelectronics, a pioneer in developing lowcost IR CO2 sensors …


IR vs TC: Settling the CO2 sensor debate once and for all ...

26/07/2016· We clearly understand that CO2 incubators maintain specific levels of CO2, temperature, and humidity for optimum cell growth. These parameters are monitored and controlled via sensors. As for CO2, there are two types of CO2 sensors commonly found in incubators: the TC (thermal conductivity) sensor and the IR (infrared) sensor. But which one is better…


Dräger Infrared Sensors Draeger

The sensor setup, selection of detectors and type of gas ingress are just a few of the factors that have a direct influence on the measuring performance of an IR sensor. Developing the sensors ourselves gives Dräger the opportunity to optimise these parameters, so they fulfil the requirements of various applications, personal monitoring, clearance measurements and leak detection.

Single Beam NDIR CO2 Carbon Dioxide Sensors|Cubic CO2 Sensor

CM1106C series is a single beam NDIR CO2 sensor, based on nondispersive infrared (NDIR) technology with independent intellectual property, which can detect CO2 concentration of indoor air. With autocalibration, no need of maintaince. With high accuracy, long term stability, small size, it is widely used for ventilation system, air purifier, air conditioner, HVAC transmitter, IAQ monitor, etc.


How do the sensor and CO2 sensor work? | AirVisual ...

How does the IR CO2 sensor work? The CO2 censor is composed of an infrared (IR) lamp, a reflective gas cell, and IR filtered detectors. The IR lamp sends waves of light towards the IR filtered detectors, which can measure how much IR light reach them. While the IR light goes through the cell, CO2 modules absorb lights of certain wavelength (shown in the graph). Thus, the number of CO2 modules ...
