OSC Based Gas Sensor for Detecting Agriculture Ammonia Water Pollution

Overabundant fertilization results in significant ammonia nitrogen pollution, which consequently triggers eutrophication. This study aims to tackle the constraints inherent in existing detection methodologies with an OSC based gas sensor, which can precisely detect 0.2 mg/L~20 mg/L ammonia nitrogen. To our knowledge, we are the first to successfully demonstrate the real-time detection of agriculture ammonia water pollution with solid state sensors.
