1. Introduction

CO click is a simple solution for adding a
™
high-sensitivity Carbon monoxide sensor
to your design. The board features an MQ-7
sensor with a Sn02 gas sensing layer, a
calibration potentiometer, a mikroBUS
host socket, two jumpers and a power
indicator LED. CO click communicates
™
with the target board through mikroBUS
AN (OUT) line. CO 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.

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

CO click can detect Carbon monoxide
™
levels in concentrations from 20ppm to
2000ppm. The MQ-7 CO sensor unit 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 CO rise. CO click
also contains a potentiometer that lets you
adjust the sensor for the environment. For
precise calibration the sensor needs to
preheat (once powered up, it takes 48h to
reach the right temperature).
