Description
Grove – Alcohol Sensor is a complete alcohol sensor module, based on MQ303A. It has good sensitivity and fast response to alcohol.
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.
Description
Grove – Alcohol Sensor is a complete alcohol sensor module for Arduino or Seeeduino. It is built with MQ303A semiconductor alcohol sensor. It has good sensitivity and fast response to alcohol. It is suitable for making Breathalyzer. 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 air.
Application
- DUI testing
- Alcohol degree testing
- Alcohol volatilization detection
