This can be done using a **Raspberry Pi** equipped with a **Grove Base Hat**, which provides easy connections for various sensors. The [**3D-PAWS software**](https://github.com/3d-paws/3D-PAWS-Raspberry-Pi), available on GitHub, simplifies the testing process by handling sensor data acquisition and communication. By following this setup, you can validate sensor functionality and accuracy in a controlled environment before deploying them in the field. You can test the following sensors on the Raspberry Pi at this time: * Anemometer * Wind Vane * Tipping Bucket Rain Gauge * Temperature, Pressure, Relative Humidity sensors * Light Sensor ### Instruction Slides for Testing the Instruments {% embed url="" %} ### Tutorial Video for Aligning the Wind Vane to 0° (N) This video demonstrates testing the Wind Vane. {% embed url="" %} --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://3dpaws.comet.ucar.edu/building-3d-paws/building-the-core-instruments/testing-the-sensors.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
