Gravity: Factory Calibrated Electrochemical Nitrogen Dioxide Sensor (0-20ppm, I2C/UART)

This electrochemical sensor precisely detects nitrogen dioxide (NO2) concentrations within a range of 0 to 20ppm, making it an invaluable tool for monitoring air quality. Designed with versatility in mind, the sensor module offers three output modes: I2C, UART (0-3V), and analog voltage. The user-configurable I2C address presents a choice of 32 unique options, providing flexibility for integration into various systems.

Factory-calibrated for accuracy, the sensor includes an integrated temperature compensation algorithm and a threshold alarm function, enhancing its reliability in diverse environmental conditions. Operating on a 3.3V to 5.5V DC supply and requiring less than 5mA working current, it is energy-efficient, making it perfect for long-term applications. The robust design ensures a service life exceeding two years in standard air.

Compatibility is a breeze with popular platforms like Arduino, ESP32, and Raspberry Pi, allowing seamless integration into existing projects or new designs. Whether setting up an indoor air quality monitor or developing a broader environmental monitoring system, this sensor offers an excellent foundation. With its long service life and stable performance, it stands out as an indispensable component in the toolkit of anyone needing reliable NO2 detection.

The sensor's electrochemical principle ensures high sensitivity and strong anti-interference capabilities, which are critical for accurate detection. With DFRobot’s easy-to-use Gravity interface and sample code, constructing a nitrogen dioxide concentration detector becomes straightforward. Additionally, the modular design allows for effortless combination with other gas detection sensors in DFRobot’s series, such as CO, O2, or H2S, providing a customizable solution for complex needs.
