CO₂ Sensors for Air Quality & HVAC Systems

Modern indoor air quality (IAQ) systems, demand-controlled ventilation (DCV), and building management systems (BMS) depend on accurate, energy-efficient CO₂ monitoring to optimise air changes without unnecessary energy waste.

Gas Sensing’s ultra-low power solid-state sensors are designed to run for years on battery power, making them ideal for wireless battery powered or energy harvesting, distributed IoT air quality systems – especially in retrofit scenarios where mains power isn’t available. By providing fast, reliable CO₂ data, our sensors help improve occupant wellbeing, ensure compliance with air quality regulations, and reduce HVAC energy costs. Providing a very low cost of ownership.

All Gas Sensing devices use proprietary mid-infrared LED technology, which drastically reduces warm-up times and power consumption compared to conventional incandescent NDIR sensors. Our sensors are trusted by leading OEMs building the next generation of smart IAQ and HVAC systems.

cozIR®-LP3

Designed for ultra-low power consumption. Ideal for wireless IAQ monitors, CO₂ alarms, and DCV systems in smart buildings.

cozIR®-BLINK-N

Extremely low average power thanks to intelligent pulsed operation. Perfect for battery- or energy-harvested BMS deployments.

CO₂ Sensors for Enclosed Spaces

On construction sites, enclosed or poorly ventilated areas can quickly lead to CO₂ build-up. Whether in basements, tunnels, or temporary structures, elevated CO₂ levels can put workers at risk of fatigue, or worse. Monitoring air quality in real time is therefore essential for worker safety and regulatory compliance.

Gas Sensing’s ultra-reliable solid-state CO₂ sensors are built for tough environments. Their low power consumption, small form factor, and resistance to dust and vibration make them ideal for portable CO₂ detectors, personal gas monitors, and battery-powered ventilation systems used across the construction and hospitality industry.

These sensors are designed to perform in high-vibration, variable-temperature conditions and deliver fast, accurate CO₂ readings. They help ensure compliance with workplace safety regulations and enable proactive air quality monitoring during commissioning and system testing.

ExplorIR®-M

Rugged and durable with a wide measurement range, suited for fixed gas detectors or mobile diagnostics in demanding construction environments.
