Technical specifications indicate the YoLink Outdoor Temperature Sensor utilizes Semtech’s LoRa (Long Range) modulation, operating on a 926.3 MHz frequency. This sub-GHz protocol facilitates radio frequency penetration through dense materials, including metal refrigerator linings and masonry, where 2.4GHz signals typically experience significant attenuation. Material analysis of the IP67-rated housing confirms a sonically welded construction for moisture resistance, though this assembly method precludes internal component repair.
Performance metrics demonstrate a "report-by-exception" logic designed to optimize battery efficiency, allowing for a 24-month operational cycle on standard AA or AAA cells. While latency for push notifications is low, the data refresh rate is constrained by these power-management protocols. Standardized testing shows factory tolerances of ±0.3°C, which can be modified via software-based calibration offsets within the proprietary application.
Functional Feature Highlights
- Communication Protocol: Proprietary LoRaWAN-based 900MHz link
- Operational Logic: Report-by-exception data transmission
- Environmental Protection: IP67-rated moisture ingress resistance
Aggregated specification data confirms a theoretical signal range of 0.25 miles in open-air conditions. The hardware architecture lacks a local liquid crystal display, necessitating a secondary interface for data visualization. Because this unit lacks an integrated screen for immediate manual verification, the smart displays category offers several architectural alternatives for creating a centralized environmental dashboard.
If a visual interface is required directly on the sensor node to complement mobile alerts, the YoLink Smart Temp & Humidity Sensor provides a similar LoRa-based radio stack with different chassis features. This device is classified within the freeze and temperature sensors hardware group, which defines the standard for specialized sub-GHz environmental monitoring.
