Icohup focuses on creating sensors that can detect various types of pollution in the environment. Their first sensor, Rium, is different from existing radioactivity sensors as it can identify radioisotopes and provide X-ray spectrum information. Rium can be deployed through fixed or mobile networks for industrial monitoring, smart city supervision, and even on drones. It offers high performance, competitive pricing, and a compact size. Icohup aims to develop pollution sensors that are both high-performing and cost-effective.
