Demo “Get the weather of Fuji mountain”
Send a request message and get the result from the autonomous agent. The resulting file is saved to IPFS and the resultant message requires a signature with a private key.

Overview
This case study explores how Robonomics Network facilitates decentralized data access using IoT devices and blockchain technology. By leveraging the Robonomics dApp connected to a weather sensor on Fuji Mountain, users can obtain real-time weather data securely and transparently.
How does it work?
Requirements:
- MetaMask Extension (Download here)
Steps to Retrieve Weather Data:
- Open the dApp: Visit the Fuji Weather Sensor page in the Robonomics dApp.
-
Install MetaMask (if needed): If MetaMask is not installed, you will be prompted to install it for the dApp to function properly.
-
Allow Connection: Connect your MetaMask wallet to the Robonomics dApp when prompted.
-
Request Sensor Data: Click the "Request current values" button to initiate the data request.
-
Sign the Message: Confirm the data request by signing a message via MetaMask. No tokens or ether are required.
-
Data Collection Process: An autonomous agent will gather the weather data from the Fuji Mountain sensor and transmit it back. Wait for the response.
-
Receive the Result: The dApp will download the result file from IPFS (InterPlanetary File System), a decentralized storage solution.
-
View Weather Data: The retrieved weather data from Fuji Mountain will be displayed in the dApp interface.
Technical Insights
- Decentralized Communication: The weather data request is processed using the Robonomics protocol, ensuring transparent communication without intermediaries.
- IPFS Storage: The results are securely stored on IPFS, with cryptographic signing ensuring data integrity.
- Autonomous Agents: Smart contracts and autonomous agents facilitate secure data collection and delivery.
Key Benefits
- Trustless Data Retrieval: No central authority is required to validate the data.
- Security: Data is cryptographically signed using the agent's private key.
- Transparency: All interactions and results are immutably stored on the blockchain and IPFS.
