1ppm NDIR CO2 Sensing & Mapping Products

Quantitative CO2 Detection at 1 ppm Resolution

Traditional Solutions

Poor Flexibility

Greenhouse gases have complex emission sources and traditional detection methods are not flexible in spotting all sources.

High Cost & Technical Bar

High budget on the device purchase and maintenance, greenhouse gases monitoring requires high accuracy and resolution.

Limited Time Granularity

The remote sensing satellite has a low time resolution.

Sniffer4D 1ppm CO2 solution provides a multi-dimensional detection system that maximizes the utilization of aerial and ground mobile monitoring, acquiring the 3D CO2 distribution information. As an innovative "Top-down" method to measure carbon emissions, our solution can help companies, governments and scientific institutions meet the needs for carbon emission detection, contributing to a net zero carbon world.

Response within Seconds

Non-dispersive Infrared (NDIR) detection method has the advantages of excellent gas selectivity & stability, quick response time, low cost, and high signal-to-noise-ratio, besides, it is less affected when exposed to hazardous gases.


When infrared light passes through the target gases, the gas molecules will absorb the infrared light with a specific wavelength. In this case, the CO2 concentration will be generated by the changes in light intensity, also known as the Lambert-Beer Law.

Achieve Top-down Approach for Efficient Environmental Monitoring

Public Transport & Service Vehicles for Ground Measuring

With the long operating hours and random driving routes, the public transport & service vehicles-mounted solution can further reduce the cost of data collection, improving efficiency in locating the fugitive emissions sources scattered in time and space.


UAVs for Aerial Measuring

With the planned flight path and regional coverage, the UAV-based detection can achieve quick data collection from low altitudes covering a large area. Together with the visualized analytical software, the system brings  real-time data display and visualization, as well as one-click result delivery for decision makers.
