US Patent:

20210041406, Feb 11, 2021

Filed:

Oct 11, 2020

Appl. No.:

17/067720

Inventors:

Ning ZENG - Silver Spring MD, US
Cory MARTIN - Washington DC, US

International Classification:

G01N 33/00

Abstract:

A system and method for monitoring environment employ a dense network of sensor nodes. The method includes obtaining environmental information by combining a plurality of observations; wherein the plurality of observations are made with in-situ sensors and remote sensors; wherein the sensors form a high-density network comprising a plurality of distributed sensors; and wherein an individual sensor node, comprising of one or more sensors, can perform automatic zero-drift or other correction by deriving calibration information from other nearby nodes' observational data. The system can monitor gas concentrations over urban areas, industrial, forest, farm, wetland, power plants and other types of surfaces.

Abstract:

A system and method for monitoring environment employ a dense network of low-cost sensor nodes. The method includes obtaining environmental information by combining a plurality of observations; wherein the plurality of observations are made with in-situ or remote sensors; wherein the sensors are of different degrees of accuracy in a way to complement each other, and of different cost, and wherein the low-cost sensors form a high-density network comprising a plurality of distributed sensors. The system can monitor gas concentrations over urban areas, industrial, forest, farm, wetland, power plants and other types of surfaces.
