Gravity NO2 Nitrogen Dioxide Sensor I2C and UART
The Gravity NO2 Nitrogen Dioxide Sensor from DFRobot is a precise, factory-calibrated sensor designed to measure nitrogen dioxide (NO2) in the air. With a measuring range from 0 to 20 ppm and the capability to communicate over analog, I2C, and UART output modes, this sensor provides a flexible solution for environmental monitoring projects, industrial applications, and more. The electrochemical measurement method ensures high accuracy, stability, and excellent interference resistance. An integrated temperature compensation and a threshold alarm enhance the reliability of the sensor. Thanks to compatibility with popular microcontrollers like Arduino, ESP32, and Raspberry Pi, the sensor can easily be integrated into existing systems.
Features:
- High precision and stability in NO2 measurement.
- Supports analog, I2C, and UART output modes.
- Longevity with a life expectancy of over two years.
- Strong anti-interference ability due to electrochemical principle.
- Easy integration thanks to the Gravity interface and compatibility with Arduino, ESP32, and Raspberry Pi.
Examples of Applications:
- Air quality monitoring in urban areas.
- Use in industrial process control for monitoring NO2 concentration.
- Environmental monitoring for detecting nitrogen dioxide pollution.
- Development of portable devices for air quality measurement.
