La Crosse Technology WS-3512U-AL 
Professional Touch Screen Wireless Weather Center 
for Barometric Pressure and Wind Measurement

The La Crosse Technology WS-3512U-AL is a barometric pressure based weather forecaster and weather station featuring touch screen operation and a PC interface. The WS-3512U is somewhat similar to the WS-3610U, including the wind and pressure functions, but with a smaller, simpler display and without rainfall functionality. Also, the WS-3512U does not display temperature or humidity, even though it uses a remote thermo-hygro sensor for wind data transmission to the main station.

The La Crosse Technology WS-3512U-AL has brushed aluminum trim panels that contrast nicely with the silver colored body and silver LCD display panel.

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-3512U-AL features a weather forecast icon, digital barometric pressure display, and a bar graph showing barometric pressure history for the last 24 or 72 hours.  Also displayed are wind speed and direction, radio controlled (atomic) time and date, and a text area that can be used to display minimum and maximum data. 

Multiple pressure- and wind-related alarms may be configured to alert you of conditions such as an impending storm, as indicated by a significant drop in barometric pressure over a 6 hour time period.

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 possibility of storms, high wind conditions, and the like). 

Compact in size at approximately 7-1/2 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. 

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.  

La Crosse Technology WS-3610U Wind Sensor
Wind Speed and Direction Sensor

The two remote sensors supplied with the station include a wind speed and direction sensor and an outdoor temperature and humidity sensor. The wind speed and direction sensor is wired to the thermo-hygro sensor (32-foot replaceable cable provided) to share power and the data uplink path. The uplink path can be either wireless (up to 330 feet in clear air) or wired via the included 32 foot-cable. Please be aware that for this weather station, the thermo-hygro sensor functions only as a wind data transmitter because the station does not display temperature and humidity.

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 size C alkaline batteries.
  • Base station can be powered by the included ac adapter, and remotes can be battery-powered by 2 size C 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 base station and the remote for power backup in case of ac power failure.


  • Wind Speed Range: 0 mph to 111.8 mph
  • Transmission Range: Up to 330 Feet
  • Transmission Frequency: 433.92 MHz
  • Swiss Precision Sensor
  • Power Requirements:
    Receiver: 3 "AA" Alkaline Batteries or Included AC Power Adapter

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-3512U-X is virtually the same as the WS-3610X products, and is compatible with WS-3610X software, except that it does not have rain functionality or a temperature and humidity display.

*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.
