Gravity CO Sensor 0-1000ppm I2C and UART

The Gravity CO Sensor from DFRobot is a highly precise, factory-calibrated sensor for detecting carbon monoxide (CO) in the air, with a measuring range of 0 to 1000 ppm. This sensor supports three output modes: Analog, I2C, and UART, making it extremely flexible for various applications. Thanks to the electrochemical measuring principles, the sensor offers high stability, sensitivity, and strong anti-interference ability. With a lifespan of over two years, it is ideal for portable devices, air quality monitoring systems, as well as industrial and mining applications where reliable air monitoring is critical. Easy integration into common microcontroller platforms such as Arduino, ESP32, and Raspberry Pi is ensured by the user-friendly Gravity interface and provided sample codes.
