BIUWING Wireless Rain Gauge — Self-Emptying Outdoor Rain Gauge with Thermometer & Indoor Console

BIUWING Wireless Rain Gauge is a self-emptying outdoor rain meter that transmits real-time rainfall and temperature to an indoor display so you can track precipitation, set alarms, and view historical accumulation without daily maintenance.

Keep an accurate, hands-off record of how much rain your garden, lawn, or property receives. The BIUWING system pairs a freeze-resistant outdoor sensor with an indoor console that shows current, hourly, daily, and multi-period rainfall totals, plus indoor and outdoor temperatures. The outdoor unit automatically clears its collector after reporting, so you don’t need to manually empty cups or worry about overflow between measurements.

How does BIUWING measure and report rainfall?

The outdoor sensor uses a tipping-cup mechanism that registers each small increment of precipitation and sends that data wirelessly to the indoor console. The console computes multiple time-based totals and shows a small graphical cylinder to make trends easy to spot at a glance.

• Real-time wireless transmission of rainfall and temperature data
• Measures now, 1-hour, 24-hour, today, 7-day, month, year and total accumulation
• Graphical display plus numerical readouts for quick trend recognition
• Self-emptying action after reporting prevents manual draining

Will it work through freezing temperatures and bad weather?

The outdoor gauge is engineered to resist freezing and continue reporting in cold conditions, while the indoor console keeps time via WWVB radio for accurate logs. Although no sensor is impervious to extreme ice buildup, the self-emptying design and durable housing reduce the risk of damage during typical winter weather.

• Freeze-resistant construction for winter monitoring
• Weatherproof exterior protects electronics from rain and snow
• Automatic emptying lowers ice and debris accumulation risk
• WWVB-synced clock keeps timestamped records accurate

How easy is installation and daily operation?

Installation is straightforward: mount the outdoor sensor in a clear area away from obstructions and place the indoor console where you can easily view readings. The units pair wirelessly, require just a few batteries, and include a blue backlight for nighttime viewing.

• Simple mount-and-pair setup for quick deployment
• Battery-powered operation—no wiring to run outdoors
• Blue backlight turns on for 15 seconds for night checks
• Programmable rain alarm and dual alarm clock functions

What additional features does the console provide?

Beyond rainfall totals, the indoor display serves as a compact weather station with indoor/outdoor temperature readouts, calendar, and alarm functions. Historical measurements and the visual cylinder help you understand precipitation patterns over time so you can better plan irrigation and outdoor activities.

• Indoor and outdoor temperature monitoring
• Calendar, daily alarms, and snooze for household use
• Historical data storage with clear numeric presentation
• Attractive design suitable for living rooms, offices, and greenhouses

Who is this for? Gardeners, homeowners, greenhouse managers, and anyone who needs reliable precipitation records without frequent maintenance will benefit from the BIUWING Wireless Rain Gauge. It’s ideal if you want precise accumulation data, customizable alerts for heavy rain, and a low-effort, freeze-resistant sensor that reports indoors. The unit is also appropriate for small farms, landscapers, and hobby meteorologists who want graphical and period-based rainfall summaries without wiring or regular cup-emptying chores.
