Watch data from anywhere at any time and avoid any potential failure due to signal conversion. - 【App Real-Time Status and Alert】View current status and 24-hour data curve even you are not at home. Set higher and lower limit to get immediate alerts for abnomities, helping you respond faster to sudden changes in environments such as greenhouses and basement storage. - 【FREE Data Storage and Export】eTHS offers world's longest FREE data storage for up to 3 years. You can view detailed data history after years and export full data to Excel file at any time for records tracking. - 【Works with Alexa/Google】eTHS works with Alexa and Google Home for voice interaction. No need to find and check sensor details in App but just ask Alexa or Google Assistant the temperature or humidity data in specific room. Use Routines in Alexa App as an event to interact with products from other brands. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CB9TMSZB | | Age Range Description | Adult | | Best Sellers Rank | 107,224 in Garden ( See Top 100 in Garden ) 363 in Hygrometers | | Brand | LinknLink | | Colour | White | | Connectivity Technology | Wi Fi | | Country Of Origin | China | | Customer Reviews | 3.9 3.9 out of 5 stars (40) | | Display Type | Digital | | EU Spare Part Availability Duration | 3 Years | | Included Components | Product, sensor cable, user guide | | Indoor Outdoor Usage | Indoor | | Item Length | 4.6 Centimetres | | Manufacturer | LinknLink Pty Ltd | | Manufacturer Part Number | eTHS | | Model Name | eTHS | | Model Number | eTHS | | Outer Material | Plastic | | Power Source | USB Powered | | Product Care Instructions | Wipe Clean | | Resolution | 0.1 degree | | Response Time | 2 seconds | | Reusability | Single Use | | Special Features | App Companion, High Accuracy | | Specification Met | [Yes] | | Style Name | Contemporary | | Unit Count | 1.0 count | | Upper Temperature Rating | 82 Degrees Fahrenheit | ## Product Details - **Age range (description):** Adult - **Brand:** LinknLink - **Colour:** White - **Connectivity technology:** Wi Fi - **Display type:** Digital - **Included components:** Product, sensor cable, user guide - **Outer material:** Plastic - **Product care instructions:** Wipe Clean - **Special feature:** App Companion, High Accuracy - **Specification met:** [Yes] ## Images ![eTHS Smart WiFi Temperature and Humidity Monitor Sensor - Image 1](https://m.media-amazon.com/images/I/41+O3hj5-xL.jpg) ![eTHS Smart WiFi Temperature and Humidity Monitor Sensor - Image 2](https://m.media-amazon.com/images/I/51Kf-pRkHdL.jpg) ![eTHS Smart WiFi Temperature and Humidity Monitor Sensor - Image 3](https://m.media-amazon.com/images/I/41JUd-2AahL.jpg) ![eTHS Smart WiFi Temperature and Humidity Monitor Sensor - Image 4](https://m.media-amazon.com/images/I/41h2AoFV2YL.jpg) ![eTHS Smart WiFi Temperature and Humidity Monitor Sensor - Image 5](https://m.media-amazon.com/images/I/51-J7avAmiL.jpg) ## Frequently Bought Together - LinknLink Thermometer and Hygrometer eTHS, WiFi Smart Temperature and Humidity Monitor Sensor, APP Phone Alert, TH2MQTT Home Assistant, Compatible with Alexa Google Home, No Hub Required - THIRDREALITY ZigBee Smart Plug 4 Pack with Real-time Energy Monitoring,15A Outlet, Zigbee Repeater,ETL Certified,ZigBee Hub Required,Work with Home Assistant,Compatible Echo Devices and SmartThings - Zooz 800 Series Z-Wave Long Range S2 USB Stick ZST39 LR, Great for DIY Smart Home (Use with Home Assistant or HomeSeer Software) --- ## 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.jp/products/574208305-eths-smart-wifi-temperature-and-humidity-monitor-sensor](https://www.desertcart.jp/products/574208305-eths-smart-wifi-temperature-and-humidity-monitor-sensor) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-20*
