Outdoor Thermometer

No home weather station is complete without an outdoor thermometer. With everything else that current weather stations can do, it's still important that they're able to take good old-fashioned temperature readings. In fact, the design of many current outdoor thermometers offers a vast improvement in accuracy over older, mercury-based designs.

With mercury thermometers, there is always a relatively large margin for error. Depending on heat index, the UV index, or any number of factors, the readings on analog thermometers could be hugely biased, and give a warped description of the day's high and low temperatures. These days, many digital thermometers for use with weather stations come equipped with certain safeguards to prevent those erroneous measurements. UV shields and built in fans allow an accurate reading of temperatures throughout the day.

Digital thermometers also offer the advantage of being able to record data automatically. Keeping detailed temperature records has never been easier. By connecting your weather station with your home computer, your records can be cataloged for as long as you want them--keeping not just temperature data on file, but also rainfall, humidity--whatever you want.

Outdoor Thermometers Will Give You Half of the Picture, But...

Just as important as an outdoor thermometer in a home weather station is a good indoor thermometer. Almost all weather stations include an indoor thermometer, either attached to the base station, or remote. Remote indoor thermometer units have many uses, including everything from monitoring wine cellar temperature and humidity to alerting you when your hot tub is ready.
