AQY 1A ‘low cost’ micro air quality monitor that produces scientifically credibledata, 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 overall showed excellent correlation for ozone, 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.

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 operating procedure is to:

• Return whole device to base

• Replace failed sensors (simple mechanical process)

• Return device to field.

• Annual maintenance ~15% of purchase cost typical.

*sensor life ~12months based on 0-50 μg/m3 annual average PM10 13

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)

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.

15

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 on data processing in the cloud before outputting a measurement

• Unlimited Aeroqual Cloud data storage, 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.

16

• 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

• Demonstration projects established in San Antonio, New Orleans, and Chicago
