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 the board all the way
into the socket.
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
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.
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.
LPG click

can detect liqueed petroleum
gas levels in concentrations from 200 to
10000 ppm. The MQ-5 LPG sensor unit has
a sensor layer made of Tin dioxide (SnO
2
),
an inorganic compound which has lower
conductivity in clean air. The conductivity
increases as the levels of LPG rise. LPG 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 24h to
reach the right temperature).
LPG click
™
is a simple solution for adding
a high-sensitivity sensor for detecting
liqueed petroleum gas leakage. The
board features an MQ-5 sensor with
a SnO
2
gas sensing layer, a calibration
potentiometer, a mikroBUS
™
host socket,
two jumpers and a power indicator LED.
LPG click
™
communicates with the target
board through mikroBUS
™
AN (OUT) line.
LPG click

is designed to use a 5V power
supply only.
