CozIR®-A Ambient Air CO2 Sensor

The CozIR®-A Ambient Air CO2 Sensor is designed to monitor CO₂ in “breathable” air up to 10,000ppm, ideally suited for Indoor Air Quality (IAQ) applications in the Food & Beverage, Aerospace and Safety markets.

The CozIR®-A Ambient Air CO2 sensor comes either cased or uncased – depending on the customers requirements. It has a variety of configurable options including voltage output, RH% and temperature sensing, making it suitable across a wide range of applications.

Additionally the COZIR®-A consumes only 3mW in continuous operation, with two carbon dioxide measurements per second, and typically consume 50 times less power than any standard NDIR sensors.

The combination of low power consumption and instantaneous start-up time meets the demand for a sensor that will allow for real time monitoring of CO₂ concentration levels and can be integrated into a battery or self powered wireless system. Optional temperature and humidity sensing are available on request.

The CozIR®-A is based on SmartIR 3.0 technology platform, which uses our patented LED technology and years of experience in solid-state NDIR sensors to deliver best-in-class power consumption, speed and performance.

We can supply an optional USB to TTL cable which gives users a fast, simple method to attach our sensors to the PC and directly view measurements.
