--- title: "Sensors & instruments platform | Nexus Observatory" description: "Weather and environment stations to WMO practice, RF spectrum sensing in the band, and calibration that is traceable, recorded and repeated." url: https://observatory.global/sensors/ publisher: Nexus Observatory Inc. updated: 2026-10-27 --- Nexus Observatory / **Sensors & instruments** # Measurements that carry their own proof. Weather and environment stations to WMO practice, RF spectrum sensing in the band, and calibration that is traceable, recorded and repeated. Every value leaves with its metadata, quality flag and provenance. Or buy the observations and leave the hardware to us: Sensing as a Service. [Plan with us](https://observatory.global/contact/) Reference architecture [The open protocol](https://observatory.global/protocol/) **Open networks**: 20 **Instruments indexed**: 153,402 **Domains**: 9 **Data as of**: 2026-10-27 **00** · Explainer ## Sensors & instruments, explained in 3D.
