Carbon Dioxide
Carbon Dioxide (CO₂) is the gas Senseair first fell in love with. Its presence significantly impacts life as we understand it, and through its analysis and comprehension, we can extract crucial data across various applications.
What is there not to love?
Sunrise
No compromise
Throughout the design of our Sunrise family of sensors there has been no compromise when it comes to measurement performance. We are proud of the result – a modern, robust solid-state design with an unmatched accuracy.
Sunlight CO₂
Our most power efficient sensor
Sunlight CO₂, or lovingly nicknamed “the potato sensor” for its ability to be powered off just a few potatoes, is our most power efficient CO₂ sensor to date. It’s ideal for battery operation, or why not solar or even wireless power operation?
But power efficiency is not all, it also happens to be remarkably reliable and accurate as well!

“The most beautiful gas to measure is carbon dioxide, because it has a very isolated and nice colour in the infrared.”

CO₂ & space
S8
The de-facto standard
The S8 revolutionized the HVAC sensor market and its interface, i.e., pinning, became a de-facto standard in the industry. The S8 family remains one of our most popular sensors due to its performance and proven quality, all in a package that has been optimized and refined over the years.
The sensors have been imitated and replicated in multiple markets—a testament we consider the highest form of praise.

Applications
Intelligent Ventilation
It’s best practice to monitor individual rooms and only ventilate them when occupied to save both on power draw and limit our impact on the environment around us.
Applications
Greenhouse Gas Monitoring
CO₂ levels are crucial in monitoring and managing greenhouse gas emissions. Industries and facilities can track their carbon footprint by measuring CO₂ levels to adhere to environmental regulations and sustainability goals.
