Protecting People, Projects and the Planet
Monitoring air quality is critical for maintaining safe, compliant and responsible worksites. Whether you're operating in construction, highways, demolition or industrial settings, poor air quality can pose risks to workers, stall progress and breach regulatory limits.
Exposure to high levels of dust and particulate matter is linked to respiratory issues and long-term health problems for workers.
The HSE estimates around 12,000 UK deaths each year are linked to occupational respiratory diseases.
CO₂, TVOCs and other gases may go undetected without continuous monitoring, creating silent risks across your site.
Environmental damage from airborne pollutants can lead to enforcement action, reputational harm and costly remediation.
Regulations around emissions and environmental impact are becoming tighter. Deploying environmental sensors helps you identify problem areas early, respond to exceedances quickly and prove compliance with relevant standards.
It’s a proactive step toward protecting your team, your site and your responsibilities as a contractor.
Track and Improve Air Quality On Site
Air quality monitoring helps you measure and manage the presence of harmful pollutants and gases that could impact health, safety and environmental compliance.
Our sensor continuously collects data on fine particulate matter (PM1, PM2.5, PM10), CO₂, TVOC, carbon monoxide, humidity, temperature and dew point.
The device captures thousands of data points every hour, storing up to 180,000 time-stamped records for trend analysis and compliance reporting.
Information is accessed remotely via Stellifii, our online reporting platform, which is available through both web and app.
The system supports multiple protocols, including Modbus RTU/TCP and MQTT, so it can be integrated easily into site-level dashboards and wider reporting frameworks.
It’s a plug-and-play unit with minimal setup, making it ideal for temporary or mobile deployment. When dust or outdoor exposure affects readings, users can quickly swap out the filter patches to keep data accurate without downtime.
Monitoring Safety and Compliance

Used Where Compliance Matters
Measuring air quality is critical for any organisation that needs to ensure compliance or protect workforce health. Typical deployment scenarios incljude:
Construction Sites: Monitor emissions from dust-generating activities and stay compliant with environmental regulations.
Demolition Projects: Track airborne particulates during structure removal to minimise risk to nearby communities.
Highways and Infrastructure Works: Detect harmful pollutants from machinery and materials, particularly in enclosed or high-traffic areas.
Quarries and Extraction Sites: Manage particulate levels and reduce dust migration beyond site boundaries.
Local Authorities and Environmental Agencies Deploy at hotspots to track urban air quality trends or support public health initiatives.
If maintaining clean, compliant and safe site conditions matters to you, this system delivers the data and control you need.
Where Detection Makes a Difference
Measure emissions from dust-heavy works like cutting, drilling and breaking. Stay compliant and protect site teams from harmful particulates.
Track air quality during structural takedowns to minimise risk to neighbours, road users and your workforce. Strengthen compliance reporting.
Monitor airborne dust and gases generated by blasting, crushing and transport activities. Reduce the risk of off-site migration and complaints.
Keep track of disturbance-related dust and emissions, particularly when working near schools, hospitals or residential areas.
Support safe delivery of infrastructure projects with real-time data on site emissions and changing environmental conditions.
Deploy in high-traffic or enclosed areas to monitor vehicle emissions and airborne particulates from roadworks and resurfacing.
Install at pollution hotspots, near schools or during major works to track air quality and inform mitigation efforts.
Deploy as part of regulatory inspections or site investigations to gather reliable, timestamped emissions data across multiple pollutants.
Part of Your Connected Site Management Ecosystem
WCCTV’s Air Quality Monitoring Sensor connects directly to Stellifii, a cloud-based platform that brings your environmental data, CCTV footage and site insights into one easy-to-use system.
All air quality readings, including particulate levels, gas concentrations and climate conditions, are logged in Stellifii in real time. Your teams can access this data remotely through a secure web portal or mobile app, with no need for on-site checks or manual downloads.
The platform allows you to set thresholds, receive instant alerts and export data for reporting, ESG documentation or local authority updates. Whether you need to respond to a dust exceedance or review site emissions for an internal audit, everything is available in one place.
By centralising your environmental monitoring with your security and safety systems, Stellifii helps reduce complexity, save time and demonstrate full control over site conditions.
What Can the Air Quality Sensor Measure?
The system tracks PM1, PM2.5, PM10, CO, CO2, TVOC, temperature, humidity and dew point. All data is stored with timestamps for easy review and reporting.
Is the Data Available in Real Time?
You can access real-time readings via the Stellifii platform through desktop or our dedicated app, provided you are connected to the same network.
How Is the Sensor Powered and Connected?
The sensor supports PoE and DC inputs, with communication via RS-485, Ethernet and Modbus protocols, making it easy to integrate into site systems. When supplied by WCCTV, sensors are typically mounted to our CCTV towers as part of a complete site package.
Can I Download the Historical Data?
Yes. Up to 180,000 records can be stored and downloaded for analysis using our supported desktop software or exported as CSV files.
Is This Suitable for Outdoor Use?
Yes. The sensor has an IP43 protection rating and is built for industrial and construction environments, including those with high vibration and dust.

Back in 2019, the UK legally committed to reaching Net Zero by 2050 which means reducing the production of greenhouse gas (GHG) emissions. Find out how CO2 monitoring sensors can support this and the other related benefits below.
The construction industry accounts for 40% of the UK’s carbon emissions and with a national target to reach net zero by 2050, the focus on net zero construction sites is increasing. The question is, what does this all mean? Find out everything you need to know below.
