Perfect for maintaining optimal conditions across a wide range of locations and uses.

Using YoLink’s industry-leading technology, this sensor monitors up to 1/4 mile in open air.
- IFTTT & Alexa Integration: trigger IFTTT applets based on high or low temperature set points reached (when device alerts). Voice query Alexa for the temperature (only; humidity not supported at this time). Triggering Alexa routines is not supported at this time.
- Customizable Alerts & Notifications: Stay informed with multiple alert options! Set custom thresholds for temperature and humidity, and choose to receive alerts via text, email, or push notifications. Apple users can bypass silent mode with "Critical Alerts," while Android offers similar options. SMS messages are limited to the total of 5 times each device plus 5. A hub and one sensor provides you with 15 free SMS per month.

It measures temperatures from -4°F to 129°F (-20°C to 54°C) and humidity from 0% to 100%, ensuring stable performance in various environments, whether in cooler temperatures or warmer conditions.
- Battery-Powered with Extended Lifespan: Powered by two AA batteries, the sensor delivers up to 5 years of continuous operation, depending on usage and environmental conditions. Receive real-time low battery alerts via the YoLink app, ensuring you're notified when it’s time for a replacement. Designed for convenience, its long-lasting battery life minimizes the need for frequent replacements, making it perfect for hard-to-reach areas and critical monitoring applications.
