Know what you breathe
MoreSense designs and builds smart indoor air quality monitors in the Netherlands. Our sensors measure CO₂, temperature, humidity, particulate matter, VOCs and NOx – and tell you at a glance when it is time to open a window or switch on the ventilation.
Why measure indoor air?
We spend around 90% of our time indoors, yet indoor air is often more polluted than the air outside. At CO₂ levels above 1,000 ppm many people already notice reduced concentration and fatigue. Fine dust, VOCs from paint and cleaning products, and NOx from cooking on gas all affect how you feel and how healthy you stay. You can't see or smell most of these pollutants – but you can measure them.
