The YoLink Outdoor Contact Sensor utilizes Semtech LoRa (Long Range) modulation within the 902-928 MHz ISM band. Technical specifications indicate an IP67 immersion-proof rating, supported by a heavy-duty gasket seal and UV-resistant ABS chassis. Performance metrics demonstrate a line-of-sight range of 0.25 miles, enabled by Chirp Spread Spectrum communication which bypasses 2.4GHz congestion.
Material analysis confirms the use of two AA batteries, providing a theoretical service life exceeding 2 years due to low-power LoRa sleep cycles. The internal reed switch is rated for 100,000 cycles, and the antenna is integrated within the housing to prevent mechanical failure in high-wind conditions. Structural dimensions are larger than indoor-specific models to accommodate the weatherproofing and power cells.
Operational logic confirms that while the LoRa radio provides superior range, a proprietary gateway is required for all application-layer notifications and automation routing.
Data suggests that for gate installations, the sensor body should be mounted on a stationary post to minimize vibration-induced fatigue on the battery contacts. The device is designed to penetrate concrete and metal obstructions more effectively than Zigbee or Wi-Fi alternatives.
The YOLINK Smart Outdoor Contact Sensor is the primary recommendation for large-perimeter monitoring where standard wireless protocols fail.
This device represents a high-durability entry in the contact sensors category, specifically engineered for external environments.
