Instruments

This photo shows the current design of the 3D-PAWS. This configuration consists of a 3-cup anemometer, wind vane, tipping bucket rain gauge, temperature, relative humidity, light, and pressure sensors. The system is designed to be adapted and installed on a variety of frames. The current design uses low-cost, easily attainable PVC pipe. However, aluminum, metal pipe, and/or wood framing can be used.

The data logger is housed in a water-proof housing unit mounted on the frame. The Power to the 3D-PAWS can be supplied using commercial power (5V is required as input) or through battery with solar power backup. The sizes of the battery and solar panel depend on location of the system.

The following sections include step-by-step instructions for assembling the 3D-PAWS instruments. A parts list is included for each instrument, along with a list of the required tools. The 3D printing files for printed parts can be found in the Downloads section.
