Environmental Monitoring
Water quality, air quality, river-level and emissions telemetry - for utilities, regulators, NGOs and ESG-driven operators.
IoT-WorkS deploys environmental sensor networks covering air quality, water quality, river level and stack emissions. Data is exported in open formats with calibration against reference sites, so it stands up in regulatory reporting and ESG disclosure rather than sitting in a vendor dashboard.
Where we deploy
3 typical use casesWater-quality + level monitoring
pH, dissolved oxygen, turbidity and level sensors deployed in streams, reservoirs and outflows. Hourly data, exception alerts.
Air-quality networks
PM2.5, PM10, NO₂ and ozone monitors deployed at street and neighbourhood scale. Open-format data, calibration-traceable.
Emissions + ESG telemetry
Stack and process emissions monitoring with audit-ready exports for environmental reporting frameworks.
What can environmental sensor networks measure?
Four families in most deployments: air, water, level and emissions. Air nodes report particulates, nitrogen dioxide and ozone at street or site scale. Water sensors cover pH, dissolved oxygen, turbidity and conductivity. Level sensors track rivers, culverts and tanks. Stack sensors report process emissions. All feed one platform, so a site with several obligations reports from one dataset rather than four systems.
- PM2.5, PM10, nitrogen dioxide and ozone at street or perimeter scale
- pH, dissolved oxygen, turbidity and conductivity for water quality
- River, culvert and tank level with flood and overflow alerting
- Stack and process emissions with audit-ready export
How accurate are low-cost sensors compared with reference monitoring?
Less accurate individually, far denser as a network - and the difference matters. Reference-grade stations underpin regulatory assessment at a small number of locations. Sensor networks answer questions reference monitoring cannot afford to: where the hotspot is, whether an intervention worked, how conditions vary across a site. We co-locate with reference instruments where available so readings are calibrated rather than merely indicative.
Defra UK-AIR air quality information (defra.gov.uk)Can telemetry support permit and discharge conditions?
It supports them by making conditions continuously visible rather than sampled. Where a permit sets limits on discharge quality or emissions, continuous logging shows the trend approaching a limit instead of a pass or fail at sampling time, and alerting gives the operator a chance to intervene first. Formal compliance sampling continues as the permit specifies; telemetry is what stops a breach being discovered retrospectively.
Environment Agency (gov.uk)How does the data reach existing reporting systems?
Through open formats and public data standards. Exports are JSON, CSV and MQTT into whatever GIS, SCADA or reporting platform is already in use, and public environmental datasets can be pulled alongside our readings for context. That keeps the sensor network a data source rather than another silo requiring its own reporting workflow.
Environment Agency open data (environment.data.gov.uk)Every vertical runs on the same engines: AI Telemetry for sensor data, Engineering services for hardware + firmware + integration, the same platform for dashboards, alerts and compliance exports. The vertical changes the asset class and the regulatory frame; the stack underneath doesn't.
Frequently asked questions
- Are these sensors accurate enough for regulatory reporting?
- They complement rather than replace reference monitoring. Networks give dense coverage for hotspot detection and intervention evidence, calibrated by co-location with reference instruments where available; formal compliance sampling continues as the permit specifies.
- What water-quality parameters can you monitor?
- pH, dissolved oxygen, turbidity and conductivity as standard, with level sensing for rivers, culverts and tanks. Additional parameters are added where a permit or catchment requires them.
- Can sensors run in remote locations?
- Yes. Multi-year battery life over LoRaWAN or NB-IoT covers sites with no power or fixed connectivity, which is the normal case for river, culvert and perimeter monitoring.
- Will alerts warn us before a limit is breached?
- That is the point of continuous logging. You see the trend approaching a threshold and can intervene, rather than discovering an exceedance at the next scheduled sample.
- Do we own the data?
- Yes, and it exports in JSON, CSV and MQTT into your existing GIS, SCADA or reporting platform, so the network is a data source rather than a separate silo.
