Cities
Municipal low-power radio or private 5G layer
A city-wide connectivity layer as digital public infrastructure.
Health: exposure measured where people live: the site at a glance. The loop, step by step: 1. A valley site at first light. 2. Sensor, link, edge and console stand ready. 3. Cloud and wind sweep up the valley. 4. The station and the vault register it. 5. Time and place are fixed to every sample. 6. Signed packets hop over the radio link. 7. Relays carry the packets without reading them. 8. The edge verifies every signature first. 9. The edge model checks it against its limit. 10. Only a confirmed result leaves the edge. 11. The alert reaches the operator console. 12. The alert arrives with its evidence attached. 13. Record, proof and action are archived together. 14. Everything settles back to idle.

Nexus Observatory/
HealthExposure, measured where people live.
Air quality, heat and water monitoring for public-health programmes, exposure data aligned with the places it affects, and connectivity for clinics at the edge of the network.

Health, field by field.
Health and environmental exposure has its own specialised fields: heat measured where people at risk live, hospital rooms that must stay within their limits, mosquitoes counted before they spread disease, and community health read in wastewater. Each field below has its own standards, stack, radio, power and crew work, from the first order to the running operation.
Specialized fieldHeat and health
Street, home and care-home heat sensing linked to heat-health warnings, so health services reach the people most at risk before a heatwave peaks.The full field →Specialized fieldHospital environments
Ventilation, pressure, temperature, medical gases and pharmacy storage in hospitals, watched continuously so critical rooms stay within their limits and every excursion is on record.The full field →Specialized fieldMosquito and vector surveillance
Counting traps, weather and standing-water sensing that track mosquitoes and the conditions they breed in, so health authorities target control before outbreaks.The full field →Specialized fieldWastewater surveillance
Flow-proportional sampling, flow and water quality at treatment plants and in sewers, giving public health early, anonymous signals of infections in a community.The full field →04The problem
What this industry has to measure.
Air quality, noise, traffic, urban heat and street flooding, with open data as a procurement credential.

Nexus Observatory Inc. is the seller of record. The data your systems collect stays yours, under the licence you choose.
Do we have to buy hardware?
No. We deliver as a managed service, a data licence or a system you own.
Can we start small?
Yes. Start with one station or one site, then grow to a fleet and a network on the same open protocol, without replacing what you bought.
Which standards do the systems meet?
Each system is drawn against the open protocol and the standards it is composed from, listed on this page.
Who issues warnings and official decisions?
Environmental exposure measurement, outside medical-device scope: no diagnosis, no treatment and no clinical decision support.
What happens after go-live?
We run the systems to a written service level, with monitoring, repair and an evidence trail, or train your team to run them.
