La Crosse Technology Weather Station C85845-INT Black — Wireless Color Display with Customizable Alerts

The La Crosse Technology C85845-INT is a wireless color weather station that displays indoor and outdoor temperature, humidity, dew point, heat index, and a dynamic forecast with customizable alerts on a large backlit screen.

Designed for homeowners who want an accurate, at-a-glance view of local conditions, this weather station pairs a vivid color display with an outdoor transmitting sensor to track real-time backyard readings. The unit shows trend arrows based on barometric changes, stores daily high and low records, and features an atomic clock that auto-updates for accuracy. You can power it continuously with the included AC adapter for full brightness or run it on batteries for a power-saving, on-demand backlight.

How does this weather station provide reliable local forecasts?

The C85845-INT generates simple, easy-to-read forecast icons and trend arrows driven by barometric pressure readings from the indoor unit and outdoor sensor. Allow about a week for the system to calibrate fully for the most accurate trend detection. Forecast output is graphical and intended for short-term home planning rather than professional meteorology.

• Color forecast icons with rising/falling trend arrows
• Barometric-based trend detection—7–10 days to stabilize
• Separate indoor/outdoor readings to compare microclimates

What temperature and humidity details can I monitor?

This station displays current indoor and wireless outdoor temperatures, relative humidity, dew point and heat index. It automatically tracks daily high and low values for both temperature and humidity, and you can set audible alerts for user-defined high/low thresholds.

• Indoor and wireless outdoor temperature and humidity values
• Dew point and heat index display modes for comfort insight
• Custom HI/LO alert settings for temp and humidity, with stored daily records

How does the display and power work for different situations?

The unit’s large color screen is backlit and offers adjustable brightness when powered by the included 5V adapter for continuous display. If you choose battery backup (3 AA for the console, 2 AA for the TX sensor, batteries not included), the station conserves power by using an on-demand backlight so battery life is extended.

• Included AC adapter supports constant, adjustable backlight
• Battery backup option—console uses 3 AA, sensor requires 2 AA (not included)
• Power-saving mode: backlight only when battery-operated

What time and alarm features are included?

The weather station contains an atomic self-setting clock that supports 12-hour or 24-hour formats and automatically adjusts for Daylight Saving Time (with on/off option). It offers a crescendo alarm with a 10-minute snooze and provides full calendar date and seven time zone settings.

• Atomic self-setting clock with DST automatic reset option
• Crescendo alarm plus 10-minute snooze function
• Selectable 12/24-hour formats and seven time zone choices
