Field observation

IoT sensors

Connect buoys, weather stations, soil probes and other field devices directly to your projects. Readings are stored against the project as raw evidence you can use in dMRV reporting.

Connect a device

Register a field sensor against one of your projects. It gets its own key and posts readings straight to OCIS over HTTPS, so data arrives without manual uploads.

Your devices

No sensors connected yet.

Device integration

Send an HTTPS POST to https://www.ozeaon.ai/api/sensors/ingest with the header Authorization: Bearer <device key>.

Up to 500 readings per request, so loggers can batch offline data.
observedAt is optional (ISO 8601 or Unix seconds) and defaults to arrival time.
Optional lat/lng for mobile devices.
Invalid rows are rejected individually; the response lists them by index.
Works with ESP32/Arduino HTTP clients, cellular loggers, and LoRaWAN network-server HTTP integrations (The Things Network, ChirpStack).
