 Understanding Weather Stations and Sensors

Stand-alone weather sensors generally measure either temperature or temperature and humidity. They come in both indoor and indoor/outdoor models, and can be either wired or wireless.

Weather stations can offer a number of different features and weather sensors. The list below gives an idea of what can be included; however, not all weather stations will have all features and/or all sensor types.

Weather Station Features

Weather Condition
measures the air temperature, measures relative humidity, and dew point temperature (indoors and outdoors), as well as the barometric pressure, wind speed/direction, wind chill, and rainfall rate (outdoors only)
Built-In Memory
records the highest and/or lowest readings for temperature, relative humidity, dew point temperature, maximum wind speed, daily and accumulated rainfall, and minimum wind chill.You can reset the memory for each weather type, separately
Weather Alarms
let you set the WX 200 to sound an alarm for each weather parameter (temperature, wind speed, rainfallrate, dew-point temperature, and soon) and alert you when a set weather condition is reached.For example,you can set the weather station toalert you when the temperature drops to near freezing
Optional PC Connection
lets you connect your weather station to a personal computer (using an optional serial cable) so you can record and store weather data on your PC using the supplied AccuWeather for Windows software
12-24 Hour Forecast
provides you with a forecast of the weather conditions most likely to occur where the WX 200 is located
Weather Symbols
show you weather conditions at a glance with sunny, party cloudy, cloudy, and rainy symbols
Mode Scanning
lets you set the weather station to continuously scan all conditions in all modes, one after the other
Measurement Unit Selection
lets you select the measurement unit (such as 12- or 24-hour time format, Fahrenheit or Celsius, and so on) that the WX 200 displays in all modes that use that unit
Clock Display with Alarm
shows the time and date, and lets you set an alarm to sound at the same time every day
Mounting Hardware
lets you easily mount the various weather station components in the locations that best suit your needs
Liquid Crystal Display
clearly displays the WX 200's digital readings and functional indicators
Display Back Light
makes the display easy to read in low light situations
Low Battery Indicator
lets you know when to change the batteries in the weather station's components
Battery Backup
powers the station and retains the station memory if AC power is disconnected or interrupted
Weather References
include a glossary of frequently used weather terms and a cloud classification chart
Mounting Hardware
lets you easily mount your weather station in a location that best suits your needs
Wind Chill Chart
to look up the wind chill factor based on the air temperature and wind speed measurements
