## 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.
