The Cambri NDIR CO₂ sensor module demonstrates  remarkable resistance towards ambient temperature and relative humidity changes, and is able to measure CO₂ concentrations at high accuracy, as shown by the intercomparison result between the sensor module and the high-precision Picarro G2401 cavity ringdown spectrometer.

Scalability

• It can perform accurate, 24/7, and high-temporal-resolution measurements of greenhouse gas CO₂ as well as multiple environmental parameters (including wind speed, wind direction, temperature, humidity, atmospheric pressure, illumination, precipitation, radiation, noise, PM₁, PM_2.5, PM₁₀, SO₂, NO₂, NO, O₃, CO, and TVOC, etc.) simultaneously.

Technological Advancement

•The data time resolution is flexibly adjustable between 20 seconds and 1 hour;

•It can accurately measure CO₂ concentrations in outdoor environments (such as 420-1000 ppm) and maintain high accuracy over a long period;

•The equipment achieves remote upgrades through automatic firmware updates and parameter changes, reducing operational and maintenance workloads;

•In the absence of a network signal, the device can back up data for at least one year, and the backed-up data can be resumed and transmitted to the server once the wireless signal is restored.

Integrated Ecological Environment Big Data Management Platform for Intelligent Data Application and Analysis

• 4G wireless transmission to the data platform, with the ability to display and apply the data on various smart terminals.
