Features:

• Atomic clock automatically sets time and date displays to WWVB radio signal (manual setting is also possible).
• Display of extensive weather data, with programmable alarm functions for certain weather conditions as well as records of all minimum and maximum values along with the time and date they were recorded.
• Indoor and outdoor temperature displays in °F or °C (user-selectable).
• Indoor and outdoor relative humidity displays.
• Air pressure reading in inHg (inches of mercury) or hPa (hecto Pascals), absolute or relative (user-selectable).
• Detailed display of rainfall data (1 hour, 24 hours, total since last reset), user-selectable for inches or millimeters.
• Self-emptying rain gauge sender.
• Wind velocity in mph, km/h, m/s, knots, or Beaufort (user-selectable)
• Wind direction display with LCD compass as well as numerical (e.g., 225°) and abbreviated characters (e.g., SW).
• Wind chill factor display.
• Dew point temperature display.
• Weather forecast display by weather icons (sunny, cloudy, rainy).
• Weather (barometric pressure) tendency indicator
• Storm warning alarm.
• Large, user-friendly LCD display of all weather data.
• LED backlight for LCD display.
• COM port for connection to your PC.
• Simultaneous display of all weather data with individual settings by the user.
• All the weather data from the base station and up to 175 sets of weather history data with user-adjustable measuring intervals can be recorded and uploaded to your PC for further processing (e.g., spread sheet, etc.).

The weather station keeps a record of minimum and maximum data for all readings, along with the time and date they occurred. These are available at the push of a button.

Both indoor and outdoor temperature indications are selectable for either °F or °C. Wind speed can be displayed in mph, knots, m/s, km/h, or Beaufort scale. Barometric pressure can be calibrated for altitude and displayed in either hPa (hecto Pascals) or inHg (inches of mercury).

The station's weather-forecasting feature senses barometric pressure over time and adjusts the indicator icons and tendency arrows to provide accurate forecasts based on pressure trends.

A programmable alarm option allows alarms to be set for certain weather conditions (such as danger of frost, possibility of storms, unfavorable air pressure and temperature tendencies, and the like). Up to 13 different alarm types, many with both high and low alarm thresholds, can be programmed and set.

The included software requires Windows^TM 98 or above and Pentium 166 MHz or higher. The PC must have 32M of RAM, 20M of hard drive space, and a CD-ROM drive to install. The included software can remove stored data from the Interface and place it in a file on the PC's hard drive. Selected data can be exported as an ASCII file for use in other programs (such as Excel). Also, graphs, charts, and data lists can be generated from the stored data (for example, wind speed and direction for January 2001).

Compact in size at approximately 6.3 inches high by 6.1 inches wide, the WS2310 base station features real wood accent columns in an oak finish on both sides of the LCD display panel. The main unit has two foldout legs for use a freestanding unit on a table, shelf, or desk, or you can mount the unit on a wall. 

All cables use standard telephone wire and modular connectors. They can be extended up to an additional 32 feet, depending on the electrical interference present in the local environment.  

The three remote sensors supplied with the station include a rainfall sensor, a wind speed and direction sensor, and an outdoor temperature/humidity sensor. Both the rainfall sensor and the wind speed and direction sensor are wired to the thermo-hygro sensor (32-foot replaceable cables provided) to share power and the data uplink path. The uplink path can be either wireless (up to 100 feet in clear air) or wired via the included 32 foot-cable.

The sensors are powered by shared batteries in the thermo-hygro remote, or by power supplied by the base station when operating in the wired mode. Powering options are as follows:

• Base station and remotes can be battery-powered, in which case the base station uses 3 AA (1.5V) alkaline batteries and the thermo-hygro remote uses 2 AA alkaline batteries.
• Base station can be powered by the included ac adapter, and remotes can be battery-powered by 2 AA alkaline batteries in the thermo-hygro remote.
• Both base station and remotes can be powered by the included ac adapter if the data-link cable is connected from the base station to the thermo-hygro remote. In this case, you can still install batteries in the remote for power backup in case of ac power failure.

  • 2 AA ( 1.5V) alkaline batteries
    OR
  • If both the base-station ac adapter and the data-link cable are used, the thermo-hygro sensor receives power from the ac adapter via the cable. In this case, batteries can be installed in the sensor to serve as power backup in case of ac failure.
