LoRaWAN Zone Leak Detection Sensor (ZLD)
An industrial-grade zone leak detection system built to identify liquid accumulation across extensive linear structural zones. Using an advanced flexible sensing cable loop alongside multi-environmental sensors tracking heat and humidity metrics, it serves as an all-in-one safeguarding layout for data centers, structural raised floor basements, and critical industrial corridors.
Key Highlights
- Expansive Linear Fluid Tracking: Utilizes a flexible sensing cable to monitor large perimeters and long utility pipes simultaneously for uniform coverage.
- Integrated Climate Analytics: Outfitted with built-in high-performance sensors evaluating relative humidity and temperature points.
- Heavy-Duty Waterproof Enclosure: Features an IP67-rated enclosure engineered to survive submerged exposures, dust buildup, and prolonged UV contact.
- Optimized 10-Year Efficiency: Managed via ultra-low-power radio telemetry to yield massive multi-year service lifespans from a single cell replacement.
- Robust Data Recovery Architecture: Stores 2,800 internal operational events safely on-device, automatically pushing records post-outage to prevent telemetry loss.
Product Overview
The ZLD system functions as a high-performance zone leak detection solution designed to catch liquid aggregation across extensive, complex linear pathways rather than single spots. It utilizes a highly flexible, heavy-duty conductive sensing rope cable matrix that can wrap easily around server room perimeters, under raised floors, or along long utility pipelines. The architecture integrates premium environmental components to constantly run precise diagnostics on ambient temperature variations and microclimate humidity limits. Engineered inside a complete IP67 weather-sealed polymer enclosure, the node resists heavy dust saturation, direct water spray, and continuous moisture pooling. Built with smart peer-to-peer protocols, it supports direct connection rules to issue an immediate shutoff command to remote valve gates without waiting for gateway or cloud internet responses.
