Gravity: Factory Calibrated Electrochemical Nitrogen Dioxide Sensor (0-20ppm, I2C&UART) SF_Sound our shield has a muchThis is a sensor that detects nitrogen dioxide concentration and supports three output modes: analog, I2C, and UART. The probe has been calibrated at the factory, which can quickly and accurately measure the concentration of Nitrogen Dioxide in the environment. Can be widely used in the detection of nitrogen dioxide in industrial, underground, and environmental protection fields. The probe adopts the electrochemical principle, has the characteristics
