WeatherLink Module SDK
Download (1.29 MB)

The WeatherLink Module SDK is a development toolkit used by developers to create WeatherLink Expansion Modules. WeatherLink modules are used to extend the functionality and capabilities of the WeatherLink software. With the WeatherLink Module SDK you can create a rich set of features that can greatly extend and enhance the WeatherLink software's functionality. An Expansion Module is a software DLL component that seamlessly integrates into the WeatherLink software. With this SDK development toolkit you can access WeatherLink's database, create menu items and dialogs boxes for the software, and use some of WeatherLink's internet features.

Note: You must use C++ when developing with this SDK and WeatherLink.

Required: WeatherLink for Windows v5.5.0 or later and a WeatherLink data logger required (6510C, 6510SER, 6510USB, 7862, 7862SR).

WeatherLink for Excel API
Download (355 KB)

The WeatherLink Excel API allows you to manage, analyze, and model Davis weather station data within the familiar user and development environment of Microsoft Excel. With the API, you can hook up a weather station, download its data (automatically or manually), and store the data in an Excel worksheet for viewing and/or analysis. The API serves as a tool with which you can build your own applications using Excel's extensive macro capabilities, Visual Basic for Applications (VBA) facilities, or simply exporting the database into another, non-Excel application. As a working example, the API includes a degree-day model that performs automatic calculations on sample archival data.

Required: WeatherLink data logger attached to a serial port (USB is not supported); Davis weather station (Perception, Weather Wizard, Weather Monitor, or GroWeather); Microsoft Excel 97.
