A world full of sensors
Vaisala's history may have begun over 80 years with commercialisation of a single “radiosonde” product, designed to measure temperature, humidity, pressure, wind speed and direction in the upper atmosphere but today the company produces over 6,000 products. From high end humidity and carbon dioxide measurementfor demanding industrial applications, to air quality measurement that protects our citizens, all these sensor technologies help us to better understand and influence our environment. There is no better example of where sensing takes a centre stage than at airports around the world. Over the last 40 years Vaisala has installed weather systems at airports in over 100 countries.
