Review: Arrived on time and as described - Worked perfect with my Ambient 2902-c. Set the channel and added it with no issues. Use it in a upright freezer on a different level, no issues. Review: Excellent refrigerator/freezer sensor...works with Ecowitt. - Impressive on many levels...this is a pretty awesome sensor for tracking and monitoring your refrigerator/freezer temperatures. This sensor seems very well made with high-quality materials. Super easy to setup, and it works perfectly with my Ecowitt Wittboy Pro system (WS90). It seems highly accurate, and has great transmission range. It has several mounting options, which is nice, and one mounting option that is not shown in the listing is using the included mounting clip (attached to the bottom of the sensor) to hold it upright on a shelf. I have configured it to send an email alert when my deep freezer reaches a certain temperature, greatly reducing any chance of food loss due to power interruptions or the door being left open. I am using Energizer Ultimate Lithium batteries for extended battery life and better performance in cold conditions. And although this sensor may seem a bit higher priced compared to other temperature sensors, it is specifically designed for use in refrigerators/freezers, and is actually a pretty solid value. This is a great refrigerator/freezer sensor and is fully compatible with the Ecowitt system...five stars all the way...highly recommend. ## Features - ALL-IN-ONE THERMOMETER & HYGROMETER: Monitor the temperature and humidity of your fridge or freezer with this simple-to-use sensor. - EASY-TO-READ DISPLAY & REMOTE MONITORING: View your readings on the sensor or connect to a compatible Ambient Weather Station or Weather Hub to monitor conditions remotely. - CUSTOMIZABLE AWN ALERTS: Add this sensor to your Ambient Weather Station or Weather Hub and set up push, email, or text alerts from your AWN Personal Dashboard. - MULTIPURPOSE MOUNTING: Use the hook to hand from a wire shelf, mount to the wall, or rest horizontally in your fridge or freezer. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D2Z64S1K | | Age Range Description | Adult | | Age range (description) | Adult | | Battery Life | 365 days | | Best Sellers Rank | 569,363 in Garden ( See Top 100 in Garden ) 1,257 in Weather Stations | | Brand | ambient weather | | Colour | Silver | | Connectivity Technology | Wireless | | Customer Reviews | 4.7 out of 5 stars 58 Reviews | | Display Type | LCD | | Included Components | Thermometer, Base | | Included components | Thermometer, Base | | Indoor Outdoor Usage | Indoor | | Item Length | 6 Inches | | Manufacturer | Ambient Weather | | Manufacturer Part Number | WH51RF | | Model Name | WH51RF | | Model Number | WH51RF | | Number of Batteries | 2 AA batteries required. | | Outer Material | Metal | | Outer material | Metal | | Power Source | Battery Powered | | Product Care Instructions | Freezer Safe, Hand Wash Only | | Resolution | 0.1° | | Response Time | 80 seconds | | Reusability | Reusable | | Smart Home Compatibility | Smart Home Compatible | | Special Features | Weather Resistant, Wireless | | Special feature | Weather Resistant, Wireless | | UPC | 816982019080 | | Unit Count | 1.0 count | | Upper Temperature Rating | 5 Degrees Celsius | ## Product Details - **Age range (description):** Adult - **Brand:** ambient weather - **Connectivity technology:** Wireless - **Display type:** LCD - **Included components:** Thermometer, Base - **Model name:** WH51RF - **Outer material:** Metal - **Power source:** Battery Powered - **Product care instructions:** Freezer Safe, Hand Wash Only - **Special feature:** Weather Resistant, Wireless ## Images ![Ambient Weather WH51RF Refrigerator Freezer Sensor - Image 1](https://m.media-amazon.com/images/I/41fL7ridQoL.jpg) ![Ambient Weather WH51RF Refrigerator Freezer Sensor - Image 2](https://m.media-amazon.com/images/I/51Err+t80rL.jpg) ![Ambient Weather WH51RF Refrigerator Freezer Sensor - Image 3](https://m.media-amazon.com/images/I/71GosyeiEPL.jpg) ![Ambient Weather WH51RF Refrigerator Freezer Sensor - Image 4](https://m.media-amazon.com/images/I/715AWit0p7L.jpg) ![Ambient Weather WH51RF Refrigerator Freezer Sensor - Image 5](https://m.media-amazon.com/images/I/71TiHYOK4gL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Arrived on time and as described *by G***8 on 16 September 2025* Worked perfect with my Ambient 2902-c.

Easily connected to my Ambient Weather ws-2000 wx. station, allowing me to see the exact internal temperatures on my app at any time. No issues whatsoever working from within the refrigerator with no wires, transmitting data to the receiver on the opposite side of the house. I used a thermometer to ensure accuracy & they were accurate to with 0.2°F. ## Frequently Bought Together - Ambient Weather WH51RF Refrigerator Freezer Sensor - Ambient Weather WH31E Thermo-Hygrometer Sensor for WS-2902, WS-2000, WS-5000, WS-1965, WS-4000, WS-3000 and ObserverIP Series Weather Stations - Ambient Weather WH31LA Leak Detector for Models WS-2000, WS-5000 Weather Stations --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/744254918-ambient-weather-wh51rf-refrigerator-freezer-sensor](https://www.desertcart.vn/products/744254918-ambient-weather-wh51rf-refrigerator-freezer-sensor) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-07-15*
