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.
- 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.
- DUI testing
- Alcohol degree testing
- Alcohol volatilization detection
