Gravity: Factory Calibrated Electrochemical Alcohol Sensor (0-5ppm, I2C&UART) Shipping:2-4 Weeks When the "do not connect"

When the "do not connect" pin is connected to ground (0v)

they will remain in continuity

* 7 Digital I/O also PWM channels

Most Arduino compatible boards should be able to handle this amount of draw but beware that some clones that use less robust VREGs could see trouble

It features an adjustable range between 5 and 15 VDC with up to 45W of power

Gravity: Factory Calibrated Electrochemical Alcohol Sensor (0-5ppm, I2C&UART) Shipping:2-4 Weeks When the "do not connect"This 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
