Description:
The DFRobot Arduino Alcohol Sensor Module provides a highly accurate and rapid solution for measuring low-level alcohol gas concentrations (0-5 ppm). Leveraging electrochemistry and factory calibration, this module offers strong anti-interference, high stability, and sensitivity, with a service life of up to 2 years. It features both I2C and UART communication, a fine resolution of 0.01 ppm (10 ppb), and a broad 3.3~5.5V input voltage range, making it ideal for integration with Arduino, ESP32, and Raspberry Pi. The user-friendly Gravity interface and provided sample code simplify the development of applications like breathalyzers and smart vehicle systems.
