General Description

The Apis monitoring station provides real-time measurements of carbon monoxide (0-20 ppm), nitrogen oxide (0-20 ppm), nitrogen dioxide (0-20 ppm), nitrogen oxides (0-20 ppm), and ozone (0-20 ppm) concentrations. The device also provides relative humidity, air temperature, dewpoint temperature, and barometric pressure measurements. Data is sent to the Apis cloud platform using an internal modem and cellular connection; users can view and download historical data on the Apis cloud platform with an active subscription.

Principle of Operation

The Apis monitoring station uses Alphasense gas sensitive electrochemical (GSE) sensors to measure gas concentrations.
