Guidelines for CO2 Sensor Selection
With an increase regarding awareness in indoor air quality (IAQ), many manufactures of ventilation equipment, air purifiers, air quality monitors and thermostats are incorporating IAQ sensors into their products. This provides homeowners and building owners information about environmental parameters, such as temperature, relative humidity, carbon dioxide (CO₂), and total volatile organic compounds (TVOC’s) in the indoor environment. In this application note, we will focus on measuring the amount of CO₂ in the air.
In 1989, Telaire started a project to develop a low cost non-dispersive infrared (NDIR) sensor to measure CO₂ concentration in air. Telaire introduced the first maintenance free CO₂ sensor in 1992, and has since obtained over 35 patents centered around CO₂ sensing technologies. We are only manufacturer that offers single and dual wavelength sensors, which pertain to the method that sensor drift is controlled.
