Students learn science best with real data they collected themselves. A school observatory of weather, air quality and seismic sensors gives every class a live record of its own place, with protocols that make the data good enough for science networks and lessons that use it. [Plan a deployment](https://observatory.global/contact/deployment/) How it works [Station Builder](https://observatory.global/studio/builder/) **Industry**: Education **Measurements**: 4 **Sources cited**: 4 1. Education · School observatories Science with their own data Students learn science best with data they collected themselves about their own place. A real observatory at school turns weather, air and earthquakes from textbook pages into live questions, and protocols make the data good enough to share with science networks. 2. What is measured Weather, air and ground A weather station on the roof measures temperature, humidity, wind and rain; an air quality sensor at the gate measures particles; a small seismometer in a quiet room records ground motion from passing trucks to distant earthquakes. Classes add their own protocol observations. InstrumentsWeather station · Air quality sensor · Seismometer 3. The base node Clean data for classes The node checks every value, flags faults so teachers know when to call for help, and publishes clean data to class dashboards and the network, so lessons start from data students can trust. Nothing is lost when a link drops; the node keeps it. 4. Radio and links On the school network Stations join the school network, so data reach classrooms without new links; schools without a reliable network use a cellular modem. Dashboards embed in the school's learning platform. Each link is chosen for the place, not from a catalogue. When one path fails, the other carries the data. LinksWi-Fi · Public cellular 5. How it works From a tremor to a lesson A distant earthquake shakes the school seismometer during a maths lesson. The next science class finds the trace, compares it with three other schools, and works out how far away the earthquake was from the arrival times. Every step is kept on the record. 6. From order to operation · Order Scope with the district The scope reads the district's schools, curriculum goals, teacher capacity and network rules. Nexus Observatory Inc. returns the station kit, lessons, teacher training, support and a price per school and per year. Every assumption in the scope is written down and priced. [Plan a deployment](https://observatory.global/contact/deployment/) 7. From order to operation · Survey Survey each school Crews visit each school with a teacher: roof or ground for weather exposure, the gate for air quality, a quiet room for the seismometer, network access and safety. Findings are recorded with photographs. Every finding is kept with the site record for the crews who follow. 8. From order to operation · Permits School and family consent The school and district approve installation, building rules for roof work are followed, and data and privacy rules for students are agreed with families. Every approval is kept with the school record. Approvals are tracked site by site, so nothing waits unseen. 9. From order to operation · Build Build and test Stations are assembled, calibrated, nodes enrolled with their identities and configured for the school network, and dashboards prepared for classes. Each kit runs before it ships. Test results travel with the kit to the site. Nothing ships until the whole kit has passed its tests together. [Open the Station Builder](https://observatory.global/studio/builder/) 10. From order to operation · Install Install with students Crews install the station with a class watching, explaining each instrument and why it sits where it does. Every part is photographed, and the teacher learns the simple checks. The site record is updated before the crew leaves. Crews follow the site safety plan throughout the work. 11. From order to operation · Commission Commission with a lesson Each node proves its identity. Readings are compared with a reference and the nearest official station, and the first lesson uses the school's own data to check them. Results are signed and kept with the site record. Acceptance is recorded with the owner before handover. 12. From order to operation · Operate Learn with live data Classes see their own weather, air and ground motion in lessons; students compare schools, record protocol observations and share data with networks. Teachers receive alerts only when something needs fixing. Reports for owners and funders come from the same record. 13. From order to operation · Maintain Remote support Faults are diagnosed remotely, parts are swapped by post or on a visit, sensors are recalibrated on the agreed plan and software updated in rings. Teachers are never left maintaining equipment alone. Spares and procedures travel with the crews. Maintenance history stays with each site for its whole life. [Book field services](https://observatory.global/contact/field-service/) 14. Data products For classes and networks Teachers and students receive live class dashboards; teachers receive lesson plans built on local data; science networks receive quality-checked data; support teams receive fault alerts, each tied to school and time. Each product carries its site, time and quality flags. [See the data products](https://observatory.global/data-products/) 15. Evidence Protocols that make it science Measurements follow the school science protocols and the WMO instrument guide, air quality is set against the health guidelines and ambient air rules, and every value keeps its calibration, so student data can stand beside official records. Records are open to the people who must check them. Drawn againstGLOBE Program protocols · WMO-No. 8 · WHO global air quality guidelines · Directive (EU) 2024/2881 16. What you get Sensing as a Service Observation networks designed, installed, operated and maintained for a monthly fee: weather, hydromet, air, seismic and environmental stations, with data delivered under a licence. Delivered as managed service and data licence, for agencies, utilities, municipalities, insurers, agribusiness. Scale: Global, multi-site, per-site pricing.

Operating contextSchool science programmes have published protocols for students to measure the environment, weather instruments have siting and exposure guidance, and air quality is set against health guidelines and ambient air rules. Data that follow these protocols can join citizen science and research networks. Hazards - Stations sited where data are useless - Sensors that fail and are never fixed - Data that stay on a classroom computer - Teachers without time to maintain equipment - Student privacy in shared data **02** What must be measured ## What, where, how often, and under which rules. Each measurement names where it is taken, how often, and the public standard or regulation behind it. Numbers in the sources column open the cited source below. | Measurement | Where | Cadence | Sources | | --- | --- | --- | --- | | Weather | A station on the roof or school ground | Every few minutes | 12 | | Air quality | A sensor at the school gate or playground | Every few minutes | 34 | | Ground motion | A small seismometer in a quiet room | Continuous | 2 | | Student observations | Protocol measurements by classes | During lessons | 2 | **03** The observation stack ## From one base unit to a network. The same blocks at every scale: instruments and a base node, a site with its radio, a fleet run as one, and a network federated on the open protocol. 1. **01** Base unit A station: weather, air quality and seismic sensors on a sensor hub with a small node.

Data products - **Live class dashboards** Teachers and students - **Lesson plans with local data** Teachers - **Quality-checked data** Science networks - **Fault alerts** Support teams Integration - **Learning platforms** Dashboards and lessons embed in the school's learning platform. - **Science networks** Data are shared with citizen science networks. - **Air quality networks** Air data are shared with local monitoring. Exchanged through OGC SensorThings API, MQTT, CSV. **07** Questions buyers ask ## Before you scope it. Do teachers need to maintain it? No. Faults are handled remotely or by our crews. Is student data private? Stations measure the environment, not students. Can data be used in research? Yes, when they follow the protocols. Does it fit the curriculum? Lessons are written for it. **08** Resources ## The sources behind this page. Public standards, regulations and guidance, cited where they apply.
