Strop de aer

General Description

The Strop de aer sensor is an air quality sensor designed to provide real-time measurement of PM2.5 and PM10 mass concentration, temperature and relative humidity. The sensor pushes data to the cloud server and data can be retrieved via Opensense Map.

Principle of Operation

The Strop de aer sensor uses Novafitness SDS011 laser particle counter which uses a light scattering method to size and count particles and then convert particle numbers to mass concentrations through proprietary algorithms. The device is also equipped with a proprietary heated inlet that activates at RH values over 60-70%.
