My previous backyard weather station was a LaCrosse Technology WS-2308 that I purchased about 3 years ago when we moved into our new house. It was a good example of “getting what you pay for”. It sort of worked, except for when it didn’t. The rain collector was the biggest issue. I replaced it once after it stopped working and when the replacement stopped working, I decided it was time to upgrade.
I purchased the Davis Instruments 6250 Vantage Vue Wireless Weather Station from AmbientWeather.com. After entering my email address to obtain their lowest prices, they were by far the cheapest merchant selling this product. The shipping was pretty slow. I ordered the item on Friday, 5/27 and it didn’t arrive until yesterday (6/6). I also ordered the 6510USB WeatherLink software and data logger to allow the weather data to be streamed to my computer.
I opened the box and was quickly and easily able to follow the included instructions to put the ISS (Integrated Sensor Suite) together. The ISS includes the following weather sensors: temperature, humidity, wind speed, wind direction and rainfall rate. It also includes a solar panel that powers the unit. A battery backup is included for operation at night.
The included console shows a number of weather parameters at once including indoor and outdoor temperature and humidity, wind speed, wind direction, wind gust, dew point, heat index, time, date, sunrise, sunset, moon phase, rainfall total, rainfall rate and a number of other items. The ISS transmits data to the console every 2.5 seconds which is a huge improvement over my old weather station. It really helps for accurate and reliable wind data.
After completing assembly of the ISS, I ran through the recommended set of tests to make sure each sensor is working properly. I then attached a 1” diameter rigid PVC pipe to the unit and mounted it to the top of the kids playset in the backyard.
Next, I attached the data logger device to the console, installed the WeatherLink software and plugged the weather logger into a USB port on my computer. When I started WeatherLink for the first time, it guided me through the initial setup. When it came time to choose the type of connection, I chose USB and received an error. After a little searching on the Internet, I found that you must choose Serial instead of USB and choose the proper COM port that was set up when the device was first plugged into the computer. A USB to Serial bridge device driver was installed that creates a virtual serial port. I’m still not sure why the software can’t support the USB connection directly.
After getting a successful connection from the console to the WeatherLink software, I was disappointed to find out that WeatherLink doesn’t support “rapid fire” updates to Weather Underground. I did some further searching and found a fantastic free software tool called Cumulus from Sandaysoft. Cumulus shows nice looking graphs and gages, supports Weather Underground Rapid Fire and also creates a really nice personal weather station website.
Overall, I’m very happy so far with my new Davis weather station! Check out my Weather Underground PWS page (displaying the rapid fire weather updates) and my personal website weather page (created by the Cumulus software).
