BUILDING CONDITIONS
Indoor air quality monitoring
Understand how occupied spaces perform, prioritise ventilation investigations and assess the effect of improvements.
For offices, schools, housing, hospitality and public buildings, a single spot reading rarely explains recurring complaints. Connected monitoring builds a picture across working hours, seasons and different rooms, helping teams decide where to look first.

01
What we monitor
Depending on the question, suitable sensors can measure carbon dioxide (CO₂), temperature, relative humidity and particulate matter such as PM2.5. Selected devices also provide VOC indicators. We choose the measurements, placement and maintenance regime around the environment rather than treating one sensor as a complete assessment of air quality.
02
Illustrative application scenario
For example, a facilities team wants to understand why several meeting rooms feel stuffy. Sensors record conditions through the occupied day. The team compares patterns with room use and ventilation schedules, investigates recurring peaks and checks whether changes improve the pattern.
CO₂ can help indicate ventilation performance in suitable occupied spaces; it does not establish that air is safe or measure every pollutant. VOC indicators need interpretation and do not identify individual chemicals.
REAL-WORLD EXAMPLE
Taikoo Place, Hong Kong
SENSO8 describes 150 indoor air quality sensors deployed across Taikoo Place, using the existing LoRaWAN network. Environmental readings, including carbon dioxide and particulate matter, give facilities teams and occupants better visibility of indoor conditions. The example shows how an established estate network can support a new application without building a separate communications system.
Third-party project featured in the LoRa Alliance success-story directory. This is not a Nesos IoT deployment; reported results relate to this project.
03
What your team sees in NesosIQ
Room and building dashboards bring current readings, historical trends and agreed threshold events together. Teams can compare locations, review how long conditions persist and share data with building-management or reporting systems through scoped integrations.
04
What a pilot should establish
Select representative spaces and define the investigation question. Validate sensor placement, measurement consistency and coverage, then review the usefulness of thresholds during normal operation. Success measures can include fewer repeat complaints, time spent investigating exceptions and measured changes after ventilation work; outcomes are assessed against the baseline.
Monitoring supports facilities decisions and targeted assessment. Where specialist exposure testing is needed, we agree that separately with the appropriate professionals.

-
No. Nesos IoT deployments use LoRaWAN, a low-power wireless standard designed for monitoring across buildings and estates, so devices do not rely on building Wi-Fi. Network design, gateway connectivity and a site survey are confirmed for each project so coverage fits the environment.
-
Your organisation does. Nesos IoT does not manage alerts or operational responses: your team defines the thresholds, notification routes and response procedures, and NesosIQ can connect to your existing systems through APIs and agreed integrations.
-
Yes. Suitable applications can share the same estate network and NesosIQ platform, so you can start with one challenge and add further monitoring as your needs grow. Our device-agnostic approach selects compatible equipment for each task.

We follow Discover, Survey, Pilot, Deploy, Integrate and Scale, starting with a focused pilot that validates measurements, coverage and the operational response. Nesos IoT is based in St Helier, Jersey, and works across the Channel Islands and beyond. Call +44 (0) 1534 753225 or email info@nesos.co.uk.
NEXT STEPS
From pilot to portfolio
We follow Discover, Survey, Pilot, Deploy, Integrate and Scale: agree the operational need, validate devices and coverage, commission the solution and connect it to the people who will act. Device choice, reporting intervals and integrations are confirmed for each project. Suitable applications can share the estate network and NesosIQ platform.
