How your AQY 1 Works
The AQY 1 does all measurement on the instrument; there is no correction of
the data on the cloud. We believe this ensures the integrity of the data and
helps to maintain confidence in the measurement. It is also in keeping with the
IoT trend for increased ‘processing at the edge’.
Fans of our ozone sensors will be pleased to know
that we’re still using our patented world class GSS
ozone sensor. Outside of the AQM and AQS
products, the GSS ozone sensor still performs
extremely well in the AQY 1 as various independent
evaluations have shown.
The NO2measurement is also unique. We’re using our selective ozone sensor
to correct for ozone interference on the electrochemical NO2sensor (a
technique patented by Aeroqual). What this means is that the AQY 1 delivers a
real NO2measurement rather than an approximation of NO2as delivered by all
other devices that use an electrochemical NO2sensor. This is because all
electrochemical NO2sensors are cross sensitive to ozone, and all
electrochemical ozone sensors are cross sensitive to NO2. Because we use a
GSS ozone sensor which is highly selective to ozone, it allows us to use this
technique to provide a highly accurate NO2measurement. The algorithm is
embedded in the device itself and occurs in real-time.
The PM2.5 and PM10 measurements are delivered by an
optical particle counter which uses a well-known light
scattering method to size and count particles and then
convert them to a mass fraction. In humid conditions light
scattering is susceptible to humidity artefacts which over-
report particulate levels due to ‘fogging’ where the
particles are encapsulated by moisture and appear larger
to the sensor than they actually are. We correct for this
effect by way of a humidity correction algorithm.

Powering up your AQY 1
Before powering up your AQY 1
-If you have a modem fitted, please insert the SIM card before first
powering up. This will ensure the AQY 1 automatically connects to
Aeroqual Cloud at start up. See SIM Card Installation on page 8.
-If you do not have a modem and/or SIM card, when the unit powers up
you can connect to the AQY 1 using WIFI. See Aeroqual Connect (via
Direct WIFI) on page 11.
Plug the power adaptor into your mains power socket. Plug the supplied
power jack into the power socket on the bottom of the AQY 1.
A green light should flash for 60 seconds then will stay on. After 60 seconds
you should hear the internal fan switching on, then on and off every seconds.
This indicates successful power on.
Power requirements
The AQY 1 requires 12VDC / 24W to operate and is supplied with a power pack
with mains power plug.

Commissioning your AQY 1
For most users, simply turning on the AQY 1 is enough. Data will start flowing.
The AQY 1 comes factory calibrated and will report measured air quality
parameters accurately.
For some users, with high data quality objectives, calibration against a ‘reference’
station is the best way to ensure highest correlation between AQY 1 and
reference. To do this install the AQY 1 at the reference station (within 10m of the
reference station inlet) allow it to run for minimum 72 hours then contact us for
further instructions (techni[email protected]m).
Looking after your AQY 1
The sensors supplied with your AQY 1 are intended to provide trouble free
operation during the useful life of its sensors subject to geographical location.

*Useful life means the time from installation until the point when the sensor can no longer be
remotely calibrated.
Calibration
Calibration parameters for the NO2, O3and PM2.5/PM10 sensors are stored on
the associated sensor board so the sensors and connected board need to be
replaced with factory calibrated sensors for either calibration or in the case of
sensor failure.
To replace the sensors refer to the next section.

Page | 17
Sensor Replacement
1. Replacing the PM2.5/PM10 Sensor
❶ Disconnect the power supply at the
bottom of the AQY 1 unit.
❷ Loosen all 4 screws (they will not come
out of the casing)
❸ Disconnect white connector at the top of
the PM sensor.
❹ Separate the PM sensor from the metal
bracket by disconnecting the white spacers.
Pull the sensor out of the sample tube
(wiggling or rotating may be required).

Page | 18
❺Insert the new PM sensor into the sample tube.
Connect using the white spacers back to the metal bracket.
Connect the white connector at the top of the new sensor.
NOTE: If you are only changing the PM sensor then you still need to
program the calibration parameters for this sensor, refer to section 3 Setting
the PM2.5/PM10 sensor calibration parameters.

Page | 19
2. Replacing NO2and O3combined sensor cartridge
❶Disconnect the 3 white data connections from the O3/NO2sensor module. The connections
are labelled PM, T/RH and RPi.
❷Unscrew the positive and negative power supply cables from the O3/NO2sensor module.
❸ Unscrew the entire sensor module from the AQY 1 back plate. The sensor module can now
be removed by pulling vertically, gently pull the sensors free from their grommets.

Page | 20
❹Never directly touch the exposed NO2sensor at the bottom. If for any reason the sensor
becomes disconnected from your replacement sensor assembly only grip the sides of the
sensor when reconnecting.
❺Connect the positive and negative power supply cables to the replacement O3/NO2sensor
module. Ensure you double check the polarity
❻Align the NO2and O3sensors with the appropriate holes in the base and place the sensor
module in position.
