Air quality click
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.
Soldering the headers
Before using your clickTM board, make sure to solder 1×8 male headers to both left and right sides of the board. Two 1×8 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.
**Plugging the board in
**
Once you have soldered the headers your board is ready to be placed into the desired mikroBUSTM socket. Make sure to align the cut in the lower-right part of the board with the markings on the silkscreen at the mikroBUSTM socket. If all the pins are aligned correctly, push the board all the way into the socket.
Essential features
Air quality clickTM is suitable for detecting ammonia (NH3), nitrogen oxides
(NOx) benzene, smoke, CO2, and other harmful or poisonous gases that impact
air quality. The MQ-135 sensor unit has a sensor layer made of tin dioxide
(SnO2), an inorganic compound that has lower conductivity in clean air than
when polluting gases are present. Air quality clickTM also contains a
potentiometer that lets you adjust the sensor for the environment you’ll be
using it.
