Seeed 101020044 Grove - Alcohol Sensor is a complete alcohol sensor module, based on MQ303A. It has good sensitivity and fast response to alcohol.
Grove - Alcohol Sensor is a complete alcohol sensor module for Arduino or Seeeduino. It is built with a MQ303A semiconductor alcohol sensor which has good sensitivity and a fast response to alcohol, making it suitable for a 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.
Highly sensitive: Making 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.
