Description

  • DFRobot Gravity NO2 Sensor (Calibrated) - I2C & UART
  • Offers high stability and high sensitivity
  • Detects Nitrogen Dioxide (NO2) gas
  • Strong anti-interference ability
  • Supports three output modes analog, I2C, and UART
  • Working Voltage: 3.3 ~ 5.5 V DC

The DFRobot Gravity NO2 Sensor (Calibrated) - I2C & UART 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 and environmental protection fields.

The probe adopts the electrochemical principle, has the characteristics of strong anti-interference ability, high stability, high sensitivity, etc., and the service life is as long as two years.
