The Vatonnati A1 is a simple air quality sensor that integrates the measurement of health-critical particles, temperature, humidity and air pressure. This model enables the measurement of 4 parameters for the particles PM1, PM2.5, PM4, PM10. The Vatonnati A1 can be used both indoor and outdoor. The Vatonnati A1 is connected directly to the server and uploads the air measurement data to the cloud / server. As soon as one log in to the server, current parameters, history and analysis of air quality parameters are available.
