mikroElektronika Air quality click MIKROE-1630 Manual

Air quality click
1. Introduction
Air quality click is a simple solution
™
for adding a high sensitivity sensor for
detecting a variety of gases that impact
air quality in homes and offices. The board
features an MQ-135 sensor, a calibration
potentiometer, a mikroBUS host socket,
™
two jumpers and a power indicator LED.
Air quality click communicates with the
™
target board through mikroBUS AN (OUT)
™
line. Air quality click is designed to use a
™
5V power supply only.

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 the
board all the way into the socket.
4. Essential features
Air quality click is suitable for detecting
™
ammonia (NH ), nitrogen oxides (NOx)
3
benzene, smoke, CO and other harmful or
2
poisonous gases that impact air quality. The
MQ-135 sensor unit has a sensor layer made
of tin dioxide (SnO ), an inorganic compound
2
which has lower conductivity in clean air
than when polluting gases are present. Air
quality click ™ also contains a potentiometer
that lets you adjust the sensor for the
environment you'll be using it in.
