these guys know their product - by MMS

when i urgently needed bits for my 3d printer - they had the parts in stock and got them to me overnight.

Oh so good - by Richard

As a digi tech teacher, I use Mindkits for various classroom resources. I also have my Ultimaker serviced there and receive quality 3D printing advice when I need it. The office staff are quick to respond and very helpful.

Jase went out of his way to come to our home on a weekend to service our 3D printer and give our son tips on how to best use his 3D printer. Love the commitment, responsiveness and excellent knowledge.

Description

This is an Arduino Alcohol sensor. It uses a MQ3 probe which can be used in a Breathalyser. It has a high sensitivity to alcohol and less sensitivity to Benzine.

The sensitivity is able to be adjusted by the potentiometer. The output is proportional to the density of gas. You can use analog reading to read the data from this sensor.

To ease the difficulty of using this sensor, a Gravity Interface is adapted to allow plug&play. The Arduino IO expansion shield is the best match for this senor connecting to your Arduino microcontrollers.
