High-accuracy NDIR carbon dioxide sensors for HVAC applications

09-06-2023 | Mouser Electronics | Test & Measurement

Mouser now stocks the Telaire T6793 CO2 high accuracy NDIR carbon dioxide sensors from Amphenol. The sensors supply engineers with a flexible CO2 platform created to interact with other microprocessor devices to measure and control CO2 levels for HVAC air quality, environmental and energy-saving applications.

The sensor is a miniature, non-dispersive, single-channel OEM CO2 sensor module with the accuracy and reliability of many larger sensors. The CO2 sensor fulfils the accuracy standards of CA Title 24 and has an accuracy rating of ±45 parts-per-million (ppm) +3% of reading in the measured range of 440ppm to 2000ppm. The sensor has a 4.4V to 5.5V supply voltage, a 200mA peak current, with a 25mA average current that calibrates with most applications. The patented Telaire ABC Logic software provides a lifetime calibration warranty, removing the need for calibration in most applications.

The sensor’s ultra-small form factor (29.97mm x 15.6mm x 8.61mm) and fast warm-up time supply an affordable gas sensing solution for OEMs with applications needing an operating temperature range of -10C to +60C and relative humidity of 0% to 95% (non-condensing).
