Gas Sensor | Carbon Dioxide Sensors | CRIR E1

Within the CRIR E1 is a sensing chamber with an infrared source at one end and a detector fitted with an optical filter at the other end. The source emits radiation at wavelengths which include the absorption band of CO₂. The filter blocks wavelengths which are not sensitive to the presence of CO₂, thereby increasing selectivity and sensitivity. As the light passes through the sensing chamber, a fraction is absorbed if CO₂ is present. The difference between the light emitted by the source and received by the detector can then be converted to a CO₂ concentration reading.

The Automatic Baseline Correction (ABC) function can automatically calibrate the sensor’s lowest reading over a pre-configured interval to 400 ppm CO₂. This enhances long term stability and may eliminate the need for calibration.

Value to Customers

• Small size
• Maintenance free for normal indoor applications
• Enhanced long term stability
• Higher accuracy: ±50 ppm ±5% of reading
• Consistency and repeatability
• Easy integration

Features

• Single channel, non-dispersive infrared technology
• Automatic Baseline Correction
• Temperature compensation
• UART digital interface

Potential Applications

• HVAC, demand controlled ventilation
• Indoor air quality (IAQ) measurement
