Weather Station

Davis Sensor Package

Our weather station hardware is a combination of a Davis Vantage Pro2 (6152), Wireless Weather Envoy, and integrated sensor suite (ISS). The ISS communicates back to both the Vantage Pro2 and Envoy wireless via a frequency hopping spread spectrum radio to transmit and receive data.

The Davis Vantage Pro2 console in mounted on the wall inside the house and provides a view into the current and daily weather conditions outside without getting online. The console runs entirely on batteries, allowing for more flexibility in where it was mounted in the house. Batteries have lasted about 8 months before flashing "low battery" warnings.

The Wireless Weather Envoy is used to download information from the sensors into our Weather Server. The Envoy was chosen because our weather server is located in a different part of the house, from where the console was installed. To keep the console in the home's living space, the Envoy was added to the solution. Installed in the Envoy is the Davis Datalogger (Windows, Serial port version). The datalogger provides serial communications between the weather server and the Envoy. Software on the weather server downloads data from the Envoy, and stores it in a database.

The ISS includes rain collector, temperature and humidity sensors, and solar panel. The anemometer is wired to the ISS but mounted above it on a pole. Temperature and humidity sensors are enclosed in a solar-powered, 24-hour fan-aspirated radiation shield. Shield combines active and passive aspiration to minimize the effects of radiation.

Server Equipment

Dell PowerEdge T710

In 2010 Castle Rock Weather was migrated from physical machines to virtualized servers.

Our virtual servers are hosted using VMware ESXi 5.x on a Dell PowerEdge T710 physical server. Castle Rock Weather is a three tier application, consisting of a MySQL database server, Windows 8.1 application server, and Apache web server. Our infrastructure provides us with a flexible, scalable, and highly available application platform.

Application Server

Davis Sensor Package

Our weather server is a dedicated application server.

It is the responsibility of the server to collects weather data through the datalogger installed in the Wireless Weather Envoy. Through a number of software packages the server is able to collect the data, store in a central database, and process this data into usage information for the website. The server then periodically uploads this information to CWOP, WeatherUnderground, our web servers.

Web Server

Ubuntu Server

Our site runs on an Apache web server, running in a virtualized Ubuntu linux server. The website is written entirely in PHP, and includes many fantastic scripts written in PHP. Many of these scripts process external weather images, information, and alerts from the National Weather Service. This makes truly a central location for all weather related Conditions, Forecasts, Information, and Warnings/Alerts. Please view our "Special Thanks" section of About US

Battery Backup

APC SmartUPS 2200

Our battery backup unit, is an APC SmartUPS 2200 that we got off Craig's List. It runs on a dedicated 20amp circuit providing battery backup and line conditioning. The APC 2200 provides power to our Weather Server, Envoy Console, Webcam, Cable Modem, Router, and Switch. In the unlikely event of a power loss, we can continue to provide weather data for a few hours. This should cover short power "blips."

Virtual Weather Station

VWS Logo

Ambient Weather's Virtual Weather Station Internet Edition (VWS) is the heart of VWS continually downloads weather data from VirtualVP, on virtual COM6 port. VWS stores this information in small working and archive databases. The software then processes the raw data into usable graphs, images, data csv files, and reports. The usable data, once transferred to our external web server, is presented to our visitors throughout the website.

Virtual Weather Station is the most widely used software package for connecting your personal computer to your weather station and the Internet, allowing you to display, plot and store data for comprehensive monitoring and analysis. Runs on all Windows 32-bit operating systems, including 95/98/NT/2000/2003/ME/XP. Virtual Weather Station brings your PC to life with a rich array of dynamic and colorful gauges, dials, graphs and charts. The desktop can be completely customized - allowing you to arrange all of the virtual instruments based on your own personal preferences or application. You have literally 1000 ways to display your data. More info...
