ObservAir Operating Manual

1. Introduction

The ObservAir is an air quality sensing platform that provides accurate
pollutant concentration measurements in real time. Key features include:
Modular: The ObservAir is centered around a black carbon (BC) sensor,
•
and can optionally monitor up to two of the following six gaseous
pollutants: CO, NO
, SO
, O
, H

Portable: The lightweight (600g) and compact (120x80x45 mm)
•
ObservAir is easily deployed in both stationary and mobile monitoring
applications.
Connected: All ObservAir units support WiFi and USB communication
•
protocols, and include a 16GB removable SD card for onboard data
storage. Units may also be supplemented with an LTE, LoRa, or SigFox
communication module and a GPS unit for location logging. An
integrated mobile app and optional data backend services enable real-
time air quality monitoring, sensor diagnostics, and data collection.
Accuracy
anywhere:
Using
•
compensation algorithms, each ObservAir is individually 'trained' to
maintain measurement accuracy even in harsh operating environments
(e.g. outdoors) where existing air quality instruments typically suffer.
Network-ready: With a 24-hour battery life, flexible wireless
•
communication options,
and environmental
ObservAir is ready for networked deployments at a moment's notice.
Flexible: Accessories are available to enable a wide range of monitoring
•
applications: Solar panels for extended stationary measurements,
mounting
and
packaging
environmentally controlled enclosures for harsh environments, etc.
The ObservAir is designed to be easily deployed anywhere, and trusted to
deliver accurate air quality measurements reliably and conveniently. If you
have any questions about integrating the ObservAir into your air quality
monitoring efforts, please contact us at [email protected].
