Seeed Grove Range of Sensors and Modules - Seeed Studio 101020044, 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.
