We're in pilot phase
Open Monitoring Platform
A global open network for real-world environmental sensing.
We're onboarding early partners — cities, universities, hardware makers, and researchers.
The problem
Environmental data is fragmented and locked behind closed systems.
Fragmented data
Outdoor environmental data is scattered across proprietary platforms and incompatible formats.
Closed ecosystems
Proprietary sensing platforms dominate, limiting access for citizens and researchers.
No standards
Lack of standard measurement formats makes integration and comparison difficult.
Limited access
Citizens, researchers, and NGOs often can't access or contribute to environmental data.
The solution
OMP provides an open, interoperable layer for outdoor environmental sensing.
- ✓ Open Measurement Protocol (OMP v1.0) — device-agnostic, standardized
- ✓ Global measurement catalog — consistent units and types
- ✓ Device registry — register and discover sensors
- ✓ API-based submission — send data via a simple API
- ✓ Public map — outdoor sensor data visible to everyone
OMP in one sentence
Deploy a sensor → Register on OMP → Send data via API → Data becomes globally accessible. Anyone can build on top.
How it works
Five steps from sensor to global data.
Deploy
Deploy an outdoor sensor node in your location.
Register
Register your device on the OMP registry.
Send
Send measurements via the OMP API.
Share
Data becomes globally accessible on the public map.
Build
Anyone can build apps and dashboards on top.
Supported measurements
Standardized environmental parameters. Any outdoor measurable parameter can be added to the global catalog.
Open Measurement Protocol
Device-agnostic JSON format with global catalog, unit enforcement, and outdoor validation.
- Device-agnostic JSON
- Global measurement catalog
- Unit enforcement
- Outdoor validation

Who can join
OMP is for everyone contributing to or using environmental data. We're in pilot phase — we're actively onboarding early partners.
For hardware manufacturers
OMP compatibility increases the value and reach of your devices.
- ✓ Increase device value — OMP compatibility makes your sensors part of a global network.
- ✓ Open integration — Simple API integration, no vendor lock-in.
- ✓ Global community — Reach municipalities, researchers, and citizens worldwide.
- ✓ Interoperability — Your devices work across deployments and with other OMP-compatible hardware.

Pilot device DIY kit
We're also working on a pilot device DIY kit — an open, build-it-yourself sensor node that works with OMP out of the box. Ideal for makers, schools, and community deployments. Stay tuned for schematics, BOM, and assembly guides.
API first
Everything you need to ingest, discover, and use environmental data.
POST /measurements
Measurement ingestion API
Submit standardized measurements from your devices.
/devices
Device registry API
Register and manage sensor devices.
/catalog
Measurement catalog API
Discover measurement types and units.
/map
Map data API
Access public map and layer data.
Open by design
OMP is built for the long term: non-proprietary, interoperable, and globally accessible.
