Sensirion Nubo Air

General Description

The Sensirion Nubo Air (Nubo Monitor One, NMO-LTE) uses proprietary contamination-resistance technology and long-lasting components to provide real-time measurements of PM1.0 and PM2.5 mass concentrations. It also measures temperature, relative humidity, pressure and dew point.

Principle of Operation

The Sensirion Nubo Air sensor uses the Sensirion SPS30 raw particulate matter sensor. The measurement principle is based on laser scattering using advanced, high resolution particle size binning. The sensor uses advanced algorithms to calculate PM1.0 and PM2.5 mass concentrations.
