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. 

The station 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, and a 24-hour air-pressure history bar graph. The weather-forecasting feature senses barometric pressure over time and adjusts the indicator icons to provide accurate forecasts based on pressure trends.

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

The WS-8035AL 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). 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, four different transmitters are available. The TX4U included with the station reports both outdoor temperature and humidity. The available TX6U reports outdoor temperature, but also has no display of its own. The available TX3U reports and displays outdoor temperature only. The available TX3UP senses temperature via a probe on a 10-foot (3-meter) wire for use in pools, spas, soil, etc., and also has a display for local viewing.  

The station's 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 (3200 km) from the WWVB transmitter.

The station is medium in size (about 10 inches tall) and smartly styled in black with contrasting brushed aluminum accent columns. 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.
