Alcohol
1. Introduction
Alcohol click is a simple solution for adding
™
a high-sensitivity alcohol gas sensor to
your design. The board features an MQ-3
sensor with a Sn02 gas sensing layer, a
calibration potentiometer, a mikroBUS
host socket, two jumpers and a power
indicator LED. Alcohol click communicates
™
with the target board through mikroBUS™
AN (OUT) line. Alcohol click is designed to
™
use a 5V power supply only.
2. Soldering the headers
Before using your click board, make sure
™
to solder 1x8 male headers to both left
and right side of the board. Two 1x8 male
headers are included with the board in
the package.
2
Turn the board upside down so that
the bottom side is facing you upwards.
Place shorter pins of the header into the
appropriate soldering pads.

Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder
the pins carefully.
3. Plugging the board in
Once you have soldered the headers
your board is ready to be placed into the
desired mikroBUS ™ socket. Make sure to
align the cut in the lower-right part of the
board with the markings on the silkscreen
at the mikroBUS socket. If all the
™
pins are aligned correctly, push....
4. Essential features
Alcohol click ™ can detect alcohol gas leves
in concentrations from 0.04 to 4mg/l. The
MQ-3 alcohol sensor has a sensor layer
made of Tin dioxide (SnO2), an inorganic
compound which has lower conductivity
in clean air. The conductivity increases as
the levels of alcohol gas rise. Alcohol click
also contains a potentiometer that lets
you adjust the sensor for the environment
you'll be using it in.
