Indoor Air Quality Monitor (IAQ) series products are the high-performance miniature air pollution monitors from Sapiens. It is designed for indoor microenvironment air quality measurement assessment. IAQ can measure a variety of combination of pollutants and can be customized according to user requirements. IAQ can also be connected with a Smart Control Relay to control other devices such as a fan, UV-C disinfection air unit (UVC) or bipolar air ionizer (BAI), based on IAQ’s measured pollutant concentrations.

Indoor Air Quality Monitor (IAQ) is a highly compact indoor air quality sensor system designed to monitor indoor air quality pollutants in real-time and see measurable results instantaneously. Additional environmental factors of Temp, Relative humidity are also included.
The Sapiens IAQ Indoor Air Quality Monitor is a cutting-edge, compact sensor system designed for real-time monitoring of key indoor air pollutants, including PM₂.₅, PM₁₀, NO, NO₂, O₃, CO, CO₂, TVOC, formaldehyde, environmental factors like temperature and humidity, and also noise measurement. With simultaneous multi-pollutant detection, advanced humidity-correction algorithms, and versatile connectivity (4G, Wi-Fi, and RS485), it delivers precise, reliable data for different scenario environments.


Sapiens IAQ can measure criteria air pollutants including particulate matter (PM₁, PM₂.₅, PM₁₀, TSP), NO₂, O₃, CO and SO₂. Additional important air pollutants such as NO, CO₂, TVOC and CH₂O are available as optional measurements

For NO₂, O₃, CO and SO₂ and NO, Sapiens PCT (Patent Cooperation Treaty) patented Pair Differential Filter (PDF) technology provides unmatched performance at ppb-level concentrations for gas sensor monitoring

The Sapiens SEIN platform offers a calibration function, which is a powerful and unique tool for quality control and assurance. This function integrates Sapiens Sensor's unique hardware capabilities
