Greenhouse gas sensors for the future

Important results from the project

The project aim was to develop TRL5 prototypes for cost-efficient sensor solutions for the greenhouse gases carbon dioxide methane and nitrous oxide, and related measurement methodology, for use in sensor networks. Development of a sensor for nitrous oxide being effective at background atmospheric levels, was not achievable within project time frames. All other goals were fulfilled according to, or in some cases beyond expectations.

Expected long term effects

For methane a promising platform and sensor prototype for continued development was realized. For carbon dioxide there are now commercialized sensors for measurements under demanding conditions. Measurement methodology and IoT solutions has been developed and validated for wireless sensor networks in complex natural environments at different weather conditions. Project results have been implemented in international research and in the SITES Water program for greenhouse gas measurements.

Approach and implementation

The project was based on collaboration between a sensor developer/producer (Senseair), one IoT developer (NEP) and an application developer (LiU). This led to a clear division of responsibilities. Senseair delivered sensors to NEP, in turn adding IoT solutions and transmitted results to LiU for tests and application development. LiU reported experiences and suggestions of improvements. This iterative approach and dialogue between different responsibility areas was seen to have high potential.
