New: AQY 1

A ‘low cost’ micro air quality monitor that produces scientifically credible data, yet is simple to set up and easy to use.

“The Aeroqual AQY multi-sensor units performed very well compared to more expensive FEM/FRM instruments and

verall showed excellent correlation for
zone, and very good correlation and

high accuracy for NO2 and PM2.5.”

AQY – API

Access the API on our cloud servers (AWS)
Rest API - use any programming language that

supports HTTP requests/replies with cookies

Supports up to one API call per second per username
Through the API you can:
Get a list of devices,
Get data for each of those devices
Get and set settings for those devices
Full details on the API available HERE.

Aeroqual Care

Aeroqual Connect and Cloud software licenses Secure data storage and backup to third party servers Remote technical support Free upgrades to the latest sensor algorithms Discounts on replacement sensors and spare parts Get sent automatic alerts on device diagnostics

Aeroqual’s support plan – two years included with purchase of the device

Maintenance & Servicing

AQY intended to be ‘no touch’ for 12 months+
Sensor life is key determinant of unscheduled

maintenance; it varies by level of PM pollution*

When sensor fails, an alert is sent, and standard
perating procedure is to:
Return whole device to base
Replace failed sensors (simple mechanical process)
Return device to field.
Annual maintenance ~10% of purchase cost typical.

*sensor life ~12months based on 0-50 μg/m3 annual average PM10

Independent test

AQ-SPEC was set up by South Coast AQMD in Los Angeles to provide independent testing of low cost air quality sensing devices. All manufacturers are invited to send devices for testing. Results are made publically available on the AQ-SPEC website.

AQ-SPEC’s summary report on the AQY:

Minimal down-time: data recovery from each unit was higher than 90%
Low intra-model variability for all measured pollutants
Ozone sensors showed excellent correlation with a more expensive FEM

instrument (R2 > 0.95)

NO2 V2 sensors showed very good correlation with a more expensive FRM

instrument (R2 > 0.74) and high accuracy

PM2.5 sensors showed very good correlation with more expensive FEM

instruments (GRIMM: R2 > 0.84 and BAM: R2 > 0.83) and high accuracy

Temperature and relative humidity sensors showed excellent correlation with the

SCAQMD Met Station sensors (T: R2 > 0.91 and RH: R2 > 0.94) Full report available here.

AQY – unique technology

O3 sensor uses Aeroqual’s patented gas sensitive semiconductor

(GSS) for unrivalled sensitivity, stability and selectivity

NO2 sensor combines patented algorithms with our O3 sensor to

eliminate cross interferences common to other ‘NO2’ sensors

Automatic baseline correction (ABC) modulates between sample

and zero flow conditions to remove diurnal and seasonal temperature and humidity effects

Light-scattering optical particle sensor has algorithms for humidity

and temperature compensation, and an anti-static inlet

1 part-per-billion (ppb) detection of O3 and NO2.

AQY vs other low cost monitors

Advanced measurement techniques – not off the shelf sensors
All measurement is done on the device – many other devices rely
n data processing in the cloud before outputting a measurement
More than 2 years’ data storage on the device, allowing for fail-

safe back-up

Aeroqual Cloud is used for data acquisition and display and

remote diagnostics. Software is bundled with the instrument providing a complete product package,

Product is backed by a decade of field experience deploying and

supporting sensor-based instruments in a wide range of outdoor ambient applications.

100 AQY devices deployed across Los

Angeles in partnership with South Coast Air Quality Management District (SC AQMD) and UCLA

Funding provided through EPA Star

Grant and NZ Government R&D funding

First 25 units have been operational

since Dec 2017, network complete by March 2018

SC AQMD is under pressure to show

progress towards rule AB617 a state law that requires ‘community-level’ air quality monitoring.

SC AQMD has access to the

data via API for their own analysis

Citizens and schools are logging

in via Aeroqual Cloud

Aeroqual is applying third party

software tools to analyse and visualise the data

A richer picture is emerging of

PM2.5, O3, and NO2 patterns in the region.

Itron (ITRI: NASDAQ) is a leading

provider of smart meters and networks for utilities and cities

Aeroqual partnered with Silver Spring

Networks, acquired by Itron early 2018

Aeroqual has integrated Silver Spring

Network’s mesh radio, enabling two- way communication over the network

AQY units are installed on smart lights

that operate on Itron’s network
