Gravity: Factory Calibrated Electrochemical Alcohol Sensor (0-5ppm, I2C&UART) Shipping:2-4 Weeks Most Arduino compatible boards shouldThis is an Arduino compatible alcohol sensor module from DFRobot with a 0 5ppm measuring range, supporting I2C and UART outputs. Aiming at fast and accurate detection of alcohol gas concentration in the air, the sensor is well applicable to the small alcohol concentration measurement in the breathalyzer, smart vehicle, and so on. Based on the electrochemistry principle, this alcohol sensor has been calibrated before the factory. It is characterized by
