DFRobot Gravity NO2 nitrogen dioxide sensor I2C and UART

The Gravity NO2 Nitrogen Dioxide Sensor from DFRobot is a precise, factory-calibrated sensor designed for measuring nitrogen dioxide (NO2) in the air. With a measurement range of 0 to 20 ppm and the ability to communicate via analog, I2C, and UART output modes, this sensor offers a flexible solution for environmental monitoring projects, industrial applications, and more. The electrochemical measurement method ensures high accuracy, stability, and excellent resistance to interference. Integrated temperature compensation and a threshold alarm function further enhance the sensor's reliability. Thanks to its compatibility with popular microcontrollers like Arduino, ESP32, and Raspberry Pi, the sensor can be easily integrated into existing systems.

Features:

• High precision and stability in NO2 measurement.
• Supports analog, I2C, and UART output modes.
• Longevity with a lifespan of over two years.
• Strong anti-interference capability due to the electrochemical principle.
• Easy integration thanks to the Gravity interface and compatibility with Arduino, ESP32, and Raspberry Pi.

Application Examples:

• Monitoring air quality in urban areas.
