YoLink Indoor Hygrometer Thermometer, 2-Year Data Storage Export, Data loger, LoRa Tech, App Push, Email, SMS, Hub Required

Features

• LoRa Technology for Unmatched Range: Say goodbye to WiFi congestion YoLink devices operate using LoRa, a long-range, low-power wireless protocol, allowing placement in challenging locations such as basements, fridges, gun safes, or barnsareas where WiFi cannot reach. While the device itself does not require WiFi or internet, a YoLink Hub (which requires an internet connection) is necessary, ensuring reliable monitoring with a range of up to 1/4 mile in open air.
• Supports 2-Year Data Tracking: Access up to 2 years of historical temperature and humidity data through the YoLink app. Review trends and export detailed records for analysis, ensuring you have comprehensive insights into your environment over time. Perfect for monitoring long-term conditions in critical areas such as nurseries, storage spaces, or greenhouses.
• Advanced Sensor Data Storage: This sensor features a robust data storage capability, recording activity at intervals as frequent as every 15 minutes. Even when not connected to the internet, the sensor can store over 64,000 events locally, ensuring no data is lost. Once reconnected, all stored data is automatically uploaded to the cloud, providing seamless and uninterrupted tracking of temperature and humidity conditions.
• High-Precision Swiss Sensors: Featuring factory-calibrated Sensirion digital temperature and humidity sensors, this device provides reliable readings to NIST standards. Typical accuracy of 0.2C (0.36F) and 2% RH ensures accurate monitoring of indoor environments without the need for manual calibration.
• Precise Temperature & Humidity Monitoring: Monitor temperature and humidity levels in real-time with high precision. Based on the sensor's refresh rule, temperature and humidity data are updated periodically to ensure accurate and reliable readings. Whether its your home, greenhouse, bedroom, nursery, or storage area, the sensor continuously syncs with the YoLink app, helping you maintain optimal environmental conditions tailored to your needs.
• Customizable Alerts & Notifications: Set personalized thresholds for temperature and humidity, and stay informed with text, email, or push notifications. Apple users can enable "Critical Alerts" to override silent mode for urgent updates. Includes up to 10 free SMS notifications per month with one hub and one sensor.
• 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 its 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.
