The La Crosse Technology WS8015U Sun/Moon Wireless Weather Station with atomic clock is a full-featured weather station that displays indoor temperature and humidity, outdoor temperature and humidity, and barometric pressure--and this is only the beginning. The station also displays the day's sunrise and sunset times and moonrise and moonset times for any of 245 North American cities, plus phases of the moon. Press a button to alternate between sunrise and sunset times and sunlight duration (in hours and minutes).

Handsomely styled in silver and black, the WS8015U is a near-professional weather station with an atomic clock. The unit provides time/day/date, indoor and outdoor temperature and humidity, barometric pressure (with history graphs), and forecasting information (including a storm warning). Also provided are sunrise and sunset times, moonrise and moonset times, length of daylight, and moon phases. Install one or two optional remote transmitters, and get outdoor temperature and humidity data from additional locations.

Outdoor temperature and humidity are transmitted to the station via an included TX4U remote sensor/transmitter. The station can actually receive signals from a total of three remote transmitters. Additional transmitters (described below) are optional and sold separately. An outdoor temperature alarm can be set at the station for each remote transmitter in use.

The WS8015U keeps a record of the minimum and maximum indoor and outdoor temperatures and humidity it has recorded. Indoor minimum and maximum readings are available at the push of a button. Outdoor minimum and maximum readings are displayed along with the current readings. A clever feature that works in conjunction with the station's indoor humidity indicator is an indoor comfort level indicator with happy and sad face icons.

The station also has a weather-forecasting feature with three indicator icons, a 30-hour air-pressure history bar graph, and an display of air-pressure changes over the past 2 hours. The weather-forecasting feature senses barometric pressure over time and adjusts the indicator icons to provide accurate forecasts based on pressure trends. A storm warning alarm is issued if air pressure drops rapidly over a 6-hour period.

An incredibly accurate radio-controlled atomic clock with calendar display and alarm (including snooze function) rounds out the many features of this station.

The WS-8015U has a wide variety of programmable functions. For example, barometric pressure can be displayed as absolute or relative in either hPa (hecto Pascals) or inHg (inches of mercury). The outdoor temperature alarms and the amount of pressure drop that triggers the storm warning alarm can be set at the station. Temperatures can be displayed in °F or °C. Time can be displayed as 12-hour or 24-hour, and the clock can be optioned to automatically adjust for daylight saving time. Even the LCD display contrast can be adjusted for any of 8 different levels.

Not only will the station operate with up to three remote transmitters, three different transmitters are available. The TX4U included with the station reports both outdoor temperature and humidity. The TX3U reports and displays outdoor temperature only. The TX3UP senses temperature via a probe on a 10-foot (3m) wire for use in pools, spas, soil, etc., and also has a display for local viewing.

The station's atomic clock calibrates itself to the world's most accurate clock every night by receiving WWVB radio transmissions. These transmissions contain time information from the U.S. atomic clock source, operated by the U.S. Commerce Department near Boulder, Colorado. The built-in antenna ensures reliable signal reception up to 2000 miles (3200km) from the WWVB transmitter.

Smartly styled in silver and black, this station is medium in size at about 10 inches tall. Its main displays are large for easy reading. An integral folding stand allows the station to be used as a freestanding unit, or it can mounted on a wall.

Great-looking and loaded with features, the WS-8015U is the next best thing to a full-fledged professional weather station. If you're serious about your weather information, this station just may be the perfect choice.

Radio-Controlled Time:

The NIST (National Institute of Standards and Technology, Time and Frequency Division) maintains a radio station, WWVB, in Ft. Collins, Colorado. The WWVB radio station derives its signal from the NIST atomic clock in Boulder, Colorado. A team of atomic physicists is continually measuring every second of every day, to an accuracy of ten billionths of a second per day. These physicists have created an international standard, measuring a second as 9,192,631,770 vibrations of a Cesium-133 atom in a vacuum.

WWVB (the stationís identification just like any other radio station) continuously broadcasts time and frequency signals at 60 kHz. The carrier frequency provides a stable frequency reference traceable to the national standard. There are no voice announcements on the station, but a time code is synchronized with the 60 kHz carrier and is broadcast continuously at a rate of 1 bit per second using pulse width modulation. The time code contains the year, day of year, hour, minute, second, and flags that indicate the status of daylight saving time, leap years, and leap seconds.

The Integral Atomic Clock:

The atomic clock integral to the WS-8015U maintains its incredible accuracy by automatically tuning into the WWVB radio signal. The built-in antenna ensures reliable signal reception up to 2000 miles (3200 km) from the WWVB transmitter. As a result, the clock will calibrate to the atomic clock not only throughout the mainland U.S. but also in much of Canada. You need only insert the batteries, wait until the signal is received, and program the desired additional settings. In locations outside of WWVB range, the clock can be manually set and will provide the high degree of accuracy of any quality quartz clock.

In a nutshell, here's how the the atomic clock works: The clock's antenna is specifically tuned for optimal reception of the 60 kHz time signal. The time signal received on the antenna is demodulated by an onboard receiver, which sends the information to the clock's CMOS microprocessor for decoding. Once your clock has automatically set its time for the first time, it ensures continuing accuracy by automatically tuning into the WWVB radio signal between midnight and 6:00 a.m. As long as your clock is kept within transmitter range, it will continue to display the absolutely precise time, automatically adjusting for summer time/winter time changeovers if the daylight saving time option is ON. Should you move your clock out of transmitter range for an extended period of time, the clock will continue to operate as a highly accurate quartz-controlled clock. Upon re-entering the transmitter range, your clock will correct itself again to the precise WWVB time signal.
