Grove Alcohol Sensor is a complete alcohol sensor module for Arduino or Seeeduino. It is built with an MQ303A semiconductor alcohol sensor. It has good sensitivity and a fast response to alcohol. It is suitable for making Breathalyzers. This Grove implements all the necessary circuitry for MQ303A like power conditioning and heater power supply. This sensor outputs a voltage inversely proportional to the alcohol concentration in the air.

Highlighted Features

• Highly sensitive: Make it possible to measure when the alcohol concentration is relatively small.
• Outstanding measurement speed: Fast response and resumes quickly after alcohol exposure.
• Grove unified socket: The sensor ensures "Plug and Play" and could be versatile for various applications.

Applications

• DUI testing
• Alcohol degree testing
• Alcohol volatilization detection
