La Crosse Technology WS-3510U-AL 
Touch Screen Wireless/Wired Barometric 
Weather Station & Forecaster with PC Interface

The La Crosse Technology WS-3510U-AL is a barometric pressure based weather forecaster and weather station featuring touch screen operation and a PC interface. The La Crosse Technology WS-3510U-AL has brushed aluminum trim panels that contrast nicely with the silver colored body and silver LCD display panel.  The WS-3510U is very similar to the WS-3610U, without wind and rainfall functionality.

Weather data is available on the backlit LCD display (which is blue when illuminated), and may also be read, stored and displayed by a connected PC. 

The WS-3510U-AL features a weather forecast icon, barometric pressure, and a bar graph displaying barometric pressure history for the last 24 or 72 hours.  Also displayed are indoor temperature and humidity,  outdoor temperature and humidity (or, alternately, dew point), radio controlled (atomic) time and date, and a text area that may be used to display minimum and maximum data. 

Multiple weather alarms may be configured to alert you of conditions such as freezing temperatures, or an impending storm, as indicated by a drop in barometric pressure over a 6 hour time period. 

Communication from the included outdoor remote sensor to the console may be wireless, with a range up to 330 feet in clear air (building construction or radio frequency interference will reduce range), or by using the included cable.  Cable operation is typically used where metal in building construction, or high levels of interference make wireless communications problematic.  Cable operation also allows the remote to be powered by the indoor power supply via the cable, avoiding reduced battery voltage problems in exceptionally cold weather.

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). 

Compact in size at approximately 7 1/4 inches high by 5 1/2 inches wide. The base station has a foldout support for use a freestanding unit on a table or desk, or you can mount the unit on a wall. 

The cable from the remote to the console uses standard telephone wire and modular connectors. It can be extended up to an additional 32 feet, depending on the electrical interference present in the local environment.  

The remote sensor supplied with the station detects outdoor temperature and humidity. The uplink path can be either wireless (up to 330 feet in clear air) or wired via the included 32 foot-cable.

The sensor is powered by batteries, or by power supplied by the base station when operating in the wired mode. Powering options are as follows:

  • Base station and remote can be battery-powered, in which case the base station uses 3 AA (1.5V) alkaline batteries and the thermo-hygro remote uses 2 size AA alkaline or Lithium batteries.
  • Base station can be powered by the included ac adapter, and the remote can be battery-powered by 2 size AA alkaline or Lithium batteries.
  • 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 base station and the remote for power backup in case of ac power failure.


  • Wireless Outdoor Humidity Range: 1% to 99%
  • Indoor Humidity Range: 1% to 99%
  • Wireless Outdoor Temperature Range : -21.8F to 157.8F
  • Indoor Temperature Range: 14.1F to 139.8F
  • Transmission Range: Up to 330 Feet

For information on included and downloadable software available with this weather station, as well as minimum system requirements, please see the Heavyweather software page.  Choose your language, and then click on Products or Instructions, as appropriate.  The WS-3510U-X is virtually the same as the WS-3610X products, and is compatible with WS-3610X software, except that it does not have wind and rain functionality.

*Please note that the com port cable included for optionally connecting the weather station to a computer is equipped with a conventional 9 pin serial connector.  Many laptop computers and some desktop computers are no longer equipped with conventional serial ports.  In this case, you can obtain a USB port to Serial port adapter cable that plugs into the USB port on your computer and offers a serial port connector to connect to the weather station.  We have tested this configuration successfully.  Please beware of one thing however.  There are actually two common types of USB ports on computers, depending upon the age of the computer, USB 1.1 and USB 2.0.  It is best to get an adapter that matches the USB port type that your computer is equipped with.  USB 2.0 adapters typically don't work on USB 1.1 ports.  USB 1.1 adapters don't always work on USB 2.0 ports.  Make sure that the adapter also works with the operating system on your computer.
