What Gas Sensing Solutions does

Gas Sensing Solutions Ltd (GSS) is a privately held Scottish designer and manufacturer of solid-state carbon dioxide and methane gas sensors, headquartered in Cumbernauld, UK and operating since 2006. The company builds its sensors on a proprietary mid-infrared LED non-dispersive infrared (NDIR) platform, with the LED structures grown in-house using Molecular Beam Epitaxy (MBE), a semiconductor process that gives GSS control over optoelectronic performance at the atomic level. This platform underpins the company's claim of substantially lower power draw, higher speed, and greater durability than incumbent incandescent NDIR sensors.

GSS organises its portfolio into three families: CozIR (ultra-low-power sensors targeting battery- and energy-harvesting IoT applications, including the recently launched Series 2 with integrated temperature and humidity); ExplorIR (wide-range sensors for harsh, rapidly changing environments up to 100% CO2); and SprintIR (high-speed sensors reaching 50 readings per second). A specialised aerospace variant, CozIR-A, is qualified to DO-160 and is in service aboard the International Space Station. All products are designed and manufactured in Cumbernauld under ISO 9001-certified processes.

The company sells directly to OEMs handling custom and integration requirements via quote-based enterprise engagement, and routes standard volume through global electronics distributors including RS Online, DigiKey, and CO2Meter. Its customer base spans four vertical segments: aerospace, building management, medical and life sciences, and agriculture and food safety. Pricing is quote-based with tiered positioning by performance (low-power, wide-range, high-speed), and the firm does not disclose public list prices.

Core offering

Gas Sensing Solutions designs and manufactures solid-state CO2 and methane sensors using proprietary mid-infrared LED technology and Molecular Beam Epitaxy (MBE) in-house manufacturing. The portfolio includes the CozIR family of ultra-low-power sensors for IoT and battery-powered applications, the ExplorIR wide-range sensors for harsh environments, and the SprintIR high-speed sensors delivering up to 50 readings per second. Sensors are sold globally as components to OEMs across aerospace, medical, building management, and agriculture sectors.

Product overview

Gas Sensing Solutions designs and manufactures solid-state NDIR CO2 and methane sensors built on proprietary mid-infrared LED technology. The product portfolio comprises three main sensor families: CozIR (ultra-low power for IoT and battery-powered applications), ExplorIR (wide-range for harsh environments), and SprintIR (high-speed up to 50 Hz). The CozIR family includes LP Series 2 (with integrated temperature/humidity sensing), LP3, Blink-N, Blink, LP2, and LP models supporting wireless IoT protocols (ZigBee, Wi-Fi, LoRaWAN, Bluetooth, SigFox, EnOcean). ExplorIR-M provides wide-range monitoring for demanding conditions. SprintIR-R and SprintIR-6S deliver high-speed sampling at 50 Hz and 20 Hz respectively. The aerospace-grade CozIR-A sensor is deployed on the International Space Station. All products are manufactured in-house using Molecular Beam Epitaxy (MBE) and backed by ISO 9001-certified quality processes.

Scale indicators3 records

Recent moves6 records

Expansion highlights5 records

Emerging players

• Sensirion: Swiss sensor manufacturer with strong presence in environmental and flow sensing, and recently entered CO2 sensing with its SCD4x product line using photoacoustic technology. Competes in the same IAQ and HVAC OEM channels with comparable ultra-low-power positioning but different underlying technology.
• Elichens: French startup developing MEMS-based gas sensors including CO2 and air quality monitoring solutions. Competes in the smart building and IAQ segments with similar technology-platform positioning but at an earlier commercialization stage than GSS.

Broad incumbents

• Siemens Smart Infrastructure: Major building automation and HVAC player with integrated IAQ sensing within its building management systems. While not a direct sensor competitor, Siemens represents the platform incumbent whose OEM choices shape demand for third-party CO2 sensors like GSS's products.
• Honeywell International: Diversified industrial conglomerate with a broad gas detection portfolio including CO2 sensors under its Honeywell Sensing & Safety unit. Competes with GSS in industrial safety, aerospace, and building management with much broader product breadth and global sales coverage.
• Vaisala: Finnish environmental and industrial measurement company with high-end CO2 and multi-gas instruments serving life science, cleanroom, and industrial customers. Overlaps with GSS in medical/life sciences and industrial safety use cases where high accuracy and reliability are required.
• Infineon Technologies (PASens / XENSIV): Semiconductor giant that has launched CO2 sensors based on photoacoustic spectroscopy, directly targeting the same ultra-low-power IoT use cases as GSS's CozIR family. Infineon brings significant scale, automotive channels, and R&D resources that dwarf GSS's standalone capabilities.

Direct peers

• Cubic Sensor and Instrument: Chinese manufacturer of NDIR and electrochemical gas sensors including CO2, competing globally in HVAC, IAQ, and industrial safety. Cubic represents the volume-scale, cost-competitive alternative to GSS's differentiated ultra-low-power and high-speed product positioning.
• Senseair: Sweden-based NDIR CO2 sensor manufacturer and the most direct competitor to Gas Sensing Solutions. Senseair offers a comparable product portfolio of CO2 sensors for IAQ, building automation, and industrial safety with similar target OEM customers, making it the closest peer in product, technology (NDIR), and business model.
• Winsen Sensor: Chinese manufacturer of NDIR and other gas sensors including CO2, competing on cost in the same OEM integration market. Winsen represents the low-cost competitive threat in commodity CO2 sensing that GSS differentiates against through ultra-low power and high-speed specifications.
• Amphenol Advanced Sensors (formerly Telaire): Amphenol's Telaire line is one of the most established NDIR CO2 sensor brands globally, serving HVAC, IAQ, medical, and industrial safety with a similar OEM design-in model. Directly competes with GSS in building management and industrial segments with broader portfolio scale.
