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.
We've released the Seeed Gas Sensor Selection Guide, it will help you choose the gas sensor that best suits your needs.

I have bought the Grove Shield for Micro:bit, and I also purchased some other sensor, say Alcohol sensor and HCHO sensor. Do they need a library for implement in microbit?Question by: admin on 2018-12-18 02:30:22
Hi there~Normarlly, if a sensor does not need a library in Arduino,then it does not need a library in micro:bit either.So you can use HCHO and Alcohol with micro:bit.RegardsAnswer by: admin on 2018-12-18 02:30:22
To do the 48 hours preheat, do i just connect the sensor, the base shield and an arduino board together and plug them into a computer/power source? Or do i have to do something with the code first?Question by: admin on 2018-12-18 02:29:46
Hi there~ Please plug this sensor into baseshield,plug the baseshild into the arduino,and connect the the arduino to you computer via USB cable, then you need to update the code and keep the code running for 48 hours. For more detail,please refer to our wiki.
