Designed for seamless integration with Alexa and IFTTT through the YoLink Hub, this sensor is ideal for freezers, greenhouses, pet cages, and more, providing professional-grade environmental control with minimal setup. ## Description “YoLink” is a proprietary wireless technology provided by YoSmart. which is based on the Semtech's LoRa wireless technology combined with the YoSmart smart home/buiding protocol, to provide the most advanced smart home/buidling devices solution. Compared to WIFI, Bluetooth, ZigBee, Z-Wave, and other smart home protocols, it has the advantages of low-power consumption, long-distance coverage (wall penetration), and anti-interference. It is the first smart building/home protocol that can be very easily setup and is a very low cost but creates a reliable, robust and more secure IoT network. Review: These work great. Have one sensor in the garage and one sensor in the basement and the base unit upstairs. The signal is strong for both sensors. The announcements are loud and clear from the base unit and the email and text messages to my phone are instantaneous with the announcement. The app info works great from anywhere. Great product. Review: The hub is an absolute pig to set up but once you have done then it’s a great piece of kit for ensuring that I’m notified if the freezer out in the garage fails. I’m using the other sensor to keep an eye on the temperature in the freezer in the house. * important to note that it will initially tell you that no internet has been found - just ignore it and carry on with the set up* ## Features - World's Longest Wireless Range - Powered by LoRa technology, the long-range yet low-power system offers the industry’s longest receiving range in the market (1/4 mile). Our long-range coverage enables its use in areas challenging for most residential Wi-Fi systems, such as basements, outdoor porch/patio areas, sheds, free-standing garages, even remote outbuildings on your property. - Environment Monitoring – Be informed of the current temperature and humidity of critical equipment and rooms, as well as receive instant notifications of changes based on your personalized criteria. Current temperature and humidity is displayed on the YoLink app, along with historical graphs, so you can monitor current and past temperature and humidity conditions. Receive email and smartphone banner alerts per your individual settings whenever a pre-set value is reached. - Low-Power Means Longer Battery Life - Because of the low power consumption, device batteries may last 2 years or more (depending on application and device usage/activity), on standard AAA Alkaline batteries (lithium batteries not required)! - YoLink Hub Required but not included - YoLink Hub is the only central controller for YoLink devices, and it connects YoLink devices to the internet and the cloud. Without YoLink Hub, this sensor does not work with the YoLink app and does not support 3rd-party integration with Alexa and IFTTT. YoLink Hub is not included, please search B07TQLKQLJ for the hub or try our Temp Humidity Sensor 2 Pack Kit with 1 Hub B08JP39RLP - Team Me Up! – Pair your sensor with a YoLink Siren Alarm for immediate attention-getting alarms. Team your sensor up with one or more YoLink Smart Plugs, to do such things as turn on a dehumidifier upon high-humidity levels, or turn a bathroom exhaust fan on upon high temperature or humidity. Utilize the app’s user-friendly automation functions to create automatic actions per your specific needs. （Products sold separately!） ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B085HTZRRR | | Item model number | YS8003 | | Manufacturer | YoSmart | | Product Dimensions | 6.3 x 6.3 x 2.6 cm; 82 g | ## Product Details - **Age range (description):** Adult - **Brand:** YoLink - **Colour:** white - **Included components:** Battery - **Special features:** Alarm ## Images ![Smart Wireless Temperature & Humidity Sensor, Wide Temp Range (-22 to 158 Degree) for Freezer, Fridge, Green House, Pet Cage Monitoring, Smartphone Alerts, Works w/ Alexa IFTTT -Hub Required - Image 1](https://m.media-amazon.com/images/I/61fhWpqwd+L.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Can you have more than one temp/humidity sensor in the same house running on the hub and app?** A: Yes, You can. One Yolink hub can support more than 200 YoLink devices in real test. YoLink Hub covers more than 300 feet indoor and 1000 feet in the open air. Normally one hub is enough for one house. Hope this answer is helpful to you **Q: How often does the sensor check the temp and humidity for automation? Is the sensor only checked after a certain number of minutes?** A: The sensor updates the app each hour, minimum, but also updates if any of the following occur: At least 0.9 F degree change over a period longer than 1 minute At least 3.6 F degree change within 1 minute At least 5% humidity changes over a period longer than 1 minute The device reaches a pre-set high or low alert level (set by the user) Or the SET button on the device has been pressed **Q: Does this work with smartthings and do i need the yolink hub?** A: Sorry, YoLink system is not compatible with smarrthings now, YoLink uses LoRa protocol and YoLink Hub is required. Thanks! **Q: I see the YoLink hub is required for all smart features. Is there an alternate way to just connect wifi and monitor from ios without the hub?** A: No, YoLink hub is required. YoLink smart devices use a special wireless technology based on LoRa, which can offer extreme long range (1000 feet compared to 100 for WiFi, outdoors, line-of-sight) and superior obstruction penetration including concrete and metal, but they do not use your WiFi. They need to wirelessly connect to one of our hubs. Thanks! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by G***M on 18 January 2026* These work great.
