## Building the 3D-PAWS

The image above shows the current design of the **3D-Printed Automatic Weather Station (3D-PAWS)**. A typical configuration includes the following sensors:

* 3-cup anemometer (wind speed)
* Wind vane (wind direction)
* Tipping bucket rain gauge (precipitation)
* Temperature and relative humidity sensor
* Atmospheric pressure sensor

Depending on the monitoring objectives, additional sensors can be added or existing sensors can be omitted.

***

## Station Structure

The 3D-PAWS system is designed to be **modular and adaptable**, allowing it to be installed on a variety of mounting structures.

The current reference design uses **PVC pipe framing**, which is inexpensive, lightweight, and widely available. However, stations can also be constructed using:

* aluminum framing
* metal pipe
* wood structures

The choice of structure typically depends on the deployment environment, available materials, and long-term durability requirements.

***

## Electronics and Power

The data logger is housed in a **waterproof enclosure** mounted on the station frame.

Power for the system can be supplied using:

* **Commercial power** (5V input), or
* **Solar power with battery storage**

When using solar power, the required **battery capacity and solar panel size** depend on the deployment location and expected solar availability.

## Assembly Instructions

The following sections provide step-by-step instructions for assembling the 3D-PAWS instruments and station components.

Each instrument page includes:

* required tools
* a parts list
* assembly instructions
* diagrams or reference images

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://3dpaws.comet.ucar.edu/building-3d-paws.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
