La Crosse Technology Wireless Outdoor Temperature & Humidity Sensor – 330 ft Range, Wall Mounted

Overview

The La Crosse Technology Wireless Outdoor Temperature & Humidity Sensor provides fast, reliable readings of outdoor conditions using a 433MHz transmission. Built for the elements, its weather‑resistant housing protects the electronics, while a battery powered setup offers flexible placement and easy maintenance. This sensor is designed to pair with compatible La Crosse clock and weather stations, delivering timely data to help you monitor microclimates around your home or outdoor spaces.

Key benefits at a glance

• Temperature range: -40°F to 140°F (-40°C to 60°C) with consistent outdoor readings
• Outdoor humidity range: 10% to 99% RH for comprehensive moisture awareness
• Wireless transmission range: up to 330 feet (100 meters) in open air
• Power: battery powered by 2 AA batteries (not included) for flexible placement
• Backward compatibility: upgraded TX141TH‑B and compatibility with multiple La Crosse weather stations

Real‑world uses

Whether you’re tending a balcony garden, monitoring a greenhouse, or planning outdoor activities, this sensor provides actionable data that helps you respond to changing conditions. Use the outdoor readings to tailor irrigation schedules, shade strategies, or HVAC planning for adjacent spaces when you’re indoors but still want visibility into outdoor climate trends.

Mounting, placement, and care

The sensor is designed for practical, durable installation. For the most accurate readings, consider the following guidelines:

• Mount on a North‑facing wall or in a well‑shaded location to minimize sun‑driven temperature skew
• Position 6 to 18 inches below eaves or under a deck rail for natural protection from direct sun and rainfall
• Mount the sensor vertically to encourage moisture drainage and long‑term reliability
• A open line of sight to your weather station helps maximize transmission, though the 330‑foot range is in open air; walls and floors can reduce this

Compatibility and setup tips

Compatibility notes help you plan a seamless setup with your La Crosse system. The sensor is designed to work with a range of La Crosse clock/weather stations and includes backwards compatibility with the TX141TH‑B family. Battery power enables flexible placement without wiring. When you’re pairing, ensure the receiver and sensor are within range and use fresh AA batteries for best performance.

What you get and what to expect

With a weather‑resistant exterior and a clear readout, this sensor offers a reliable way to track outdoor climate conditions over time. It’s suited for homes, decks, gardens, and patios, helping you observe trends and make informed, non‑prescriptive decisions about outdoor timing and care. Note that results can vary with obstructions and mounting specifics.
