IAQ Monitors
Make indoor environments safer, healthier, and more comfortable with advanced sensor monitoring
People spend up to 90% of their time indoors, but often don't think about the quality of the air they breathe. Unlike outdoor air, indoor air tends to be continuously recycled, trapping pollutants and allowing them to build up in confined spaces.
IAQ monitors use air quality monitoring sensors to measure and evaluate key environmental parameters in real time. They track and report on air conditions in real time to help building owners reduce the health risks associated with poor indoor air quality. Air quality monitors typically measure PM 2.5, CO2, volatile organic compounds, temperature and humidity.
The exceptional accuracy and reliability of our environmental sensors, combined with their miniature size, make them ideal for devices such as indoor air quality monitors. Our broad portfolio is designed to meet specific customer needs.
How our indoor air quality monitoring sensors make a difference
Humidity and temperature build the base
Our humidity and temperature sensors are designed to deliver maximum accuracy in the smallest size at a competitive price. Our comprehensive expertise in design-in and algorithms helps manufacturers in the development of reliable and high-performance devices.
Innovation drives environmental sensor technology
We are deeply committed to innovation and providing our customers with the latest technology. Our extensive portfolio of environmental sensors addresses the need to monitor indoor air quality, by providing our customers with accurate, cost-effective, and miniaturized sensor solutions.
Cost-efficient and fast design-in with combo modules
Our combo modules integrate multiple sensors in one platform, measuring up to 9 environmental parameters. They eliminate the complexity of sensor integration and development, reducing time to market and development costs.

The air we share: Understanding the critical role of CO₂ in cognitive performance and infection risk
Every day, people spend up to 90% of their time indoors in offices, schools, homes, vehicles, and venues where air is constantly
inhaled, shared, and recirculated. The quality of this air remains largely invisible. Two important consequences of poor indoor air
quality are also among the least recognized: the impact on cognitive performance and risk of viral exposure.
