More reliable urban CO2 mapping

CEA-Leti designed a secure circuit board to provide near-sensor data processing. The boards, made up of microcontrollers and hardware security chips, will be tested on CO2 sensors in major cities in 2023.
Once the data gathered by the sensors is processed, it will be sent to a blockchain to ensure full traceability, and then saved to a database.
The sensor testing campaign is part of the European Icos project, whose objective is to map CO2 emissions on an international scale. CEA-Leti is helping develop a secure solution capable of delivering reliable measurements.
The circuit boards being tested here were developed together with CEA-List as part of the Green Blockchain moonshot project.
In related news, several other security solutions are being investigated in IRT Nanoelec projects.
