Air Pollution Monitoring System - Provides reliable measures of gaseous pollutants, PM1/PM2.5/PM10 particulates, EM fields, radioactivity (α, β, γ), temperature, pressure and humidity, thanks to high precision and accuracy pre-calibrated sensors
Compact and Lightweight - The small size and lightness makes the ReliaSENS 19-15 ideal for fixed (e.g. light poles) and mobile installations (e.g. construction sites)
Real Time Data - Cellular and Wi-Fi connectivities allow to connect the device to the Cloud, send data and read sensors measures in real time, 24/7
EC Ready - The Eurotech Everyware Cloud web interface enables remote device management and data access


The ReliaSENS 19-15 is a compact and easy to install environment monitoring system that collects air quality parameters, electromagnetic fields, ionizing radiation levels, in order to enable trend and outlier analysis . It is an indicative instrument to get the AQI (Air Quality Index), which is a synthetic computed value that can indicate how polluted the air is, or it is forecast to become.

The ReliaSENS 19-15 is the ideal solution for private and public agencies that need to get real-time 24/7 data, scaling from a single device to a large monitoring network.

The ReliaSENS 19-15 supports the Eurotech Everyware Cloud (EC) platform: data can be displayed in real-time, and thresholds on the collected metrics can be set, in order to enable the generation of automatic alert messages. System-generated metrics, graphics and charts are also available on EC. 

Data can be easily exported and integrated with existing IT systems to perform statistical analyses, and to identify spatial and time patterns related to pollutant generation and propagation.
