Senseair

What Senseair does

Senseair AB is a Swedish designer and manufacturer of Non-Dispersive Infrared (NDIR) air and gas sensors, founded in 1989 and headquartered in Delsbo, Sweden, with manufacturing in Delsbo and an R&D center in Västerås operated in partnership with majority owner Asahi Kasei Microdevices Corp. (99.50% stake since 2018). Its product portfolio spans three solution areas: carbon dioxide sensing (S8, S88, S88 GH, S12, Sunrise, Sunlight CO2, LP8, K30, K33, aSENSE and eSENSE transmitters), alcohol detection (A ONE, Workplace, SafeStart connected platform, Go vehicle interlock), and refrigerant leak detection (Sunlight R290/R32/R454, RDS systems). Core technology is a single-beam NDIR architecture with proprietary Automatic Baseline Correction (ABC) and Platinum EQC coating, delivering maintenance-free, 15+ year operation in compliance with ANSI/ASHRAE 62.1-2022.

The company sells primarily as an OEM module supplier and integrated solution provider to HVAC and building-automation manufacturers, automotive safety programs (DADSS, Maryland DOT), public-transit and municipal fleets, safety-equipment providers, and agricultural/greenhouse operators. Go-to-market combines direct enterprise sales teams across EMEA, the Americas, and Asia (offices in Sweden, China, South Korea, Japan, and the US) with a global distributor network and an active trade-show presence at Sensor+Test, AHR Expo, ISH, electronica, and Automechanika. Revenue is hardware-driven (sensor modules and integrated transmitters) with subscription-style add-ons such as the SafeStart web platform and professional calibration/support services; pricing is quote-based via multi-year contracts.

Senseair's strategic positioning is reinforced by participation in EU-funded research consortia (ULISSES, FLAIR, MAX-FRESH) for next-generation optical gas sensing, and a joint venture with Talkpool (Ventelligence) extending into connected indoor air quality monitors. Approximately one-third of staff are dedicated to R&D, and recent launches (S12 CO2 in January 2026 with 2026 mass production, S88 GH, and the Sunlight/RDS refrigerant family) underscore a deliberate expansion from core HVAC IAQ into refrigerant safety, greenhouse agriculture, and automotive/fleet alcohol interlock use cases.

Core offering

Senseair designs, manufactures, and sells Non-Dispersive Infrared (NDIR) air and gas sensor modules and integrated transmitters for OEMs and system integrators. Its product portfolio centers on three solution areas: carbon dioxide (CO2) sensing for HVAC and building automation, breath alcohol detection for workplace and automotive safety, and refrigerant leak detection for HVAC-R systems. The company sells sensor modules, packaged transmitters, and the SafeStart web-based management platform for fleet alcohol screening.

Product overview

Senseair is a technology company specializing in NDIR (non-dispersive infrared) air and gas sensing solutions. The product portfolio is organized around three main solution areas: Carbon Dioxide (CO₂), Alcohol detection, and Refrigerants. The CO₂ sensing line includes multiple sensor modules and transmitters: the ultra-compact S12 CO₂ and S88 series for HVAC applications, the Sunrise and Sunlight CO₂ platforms for power-sensitive applications, S8 family sensors for commercial/residential use, LP8 for low-power battery applications, and K30/K33 OEM modules for integration into third-party products. The aSENSE and eSENSE transmitter families provide wall-mounted, duct, and VAV solutions for building climate control. The alcohol detection portfolio spans the A ONE sensor for OEM integration, Workplace for high-throughput screening, SafeStart as the connected software platform, and Go/Salus for vehicle interlock applications. The refrigerant detection line includes Sunlight R290 for propane, Sunlight R32 & R454 for A2L gases, and RDS (Refrigerant Detection System) variants. The company also develops prototype multi-gas sensing platforms (K96) and participates in collaborative projects like FLAIR for drone-based air quality monitoring and ULISSES for miniaturized optical gas sensors on a chip.
