LoRaWAN Spot Leak Detection Sensor (SLD)
An advanced, compact spot leakage detection sensor engineered to detect the early presence of water or conductive liquids while simultaneously logging environmental ambient status. Fully IP67 waterproof and UV-resistant, it features high-precision built-in temperature and humidity sensors alongside ultra-long-distance LoRaWAN wireless capabilities for robust data collection in offices, basements, and critical facility infrastructures.
Key Highlights
- Instant Spot Leak Detection: Uses a localized high-sensitivity conductive probe to catch fluid presence immediately at a 5mm threshold level.
- Integrated Ambient Logging: Embedded with high-resolution sensors capturing ambient temperature and relative humidity continuously.
- Weatherproof IP67 Enclosure: Designed with robust UV-resistant materials making it highly resilient for both extreme indoor and demanding outdoor facilities.
- Up to 10 Years Battery Uptime: Powered via an easily replaceable high-capacity battery system minimizing hardware maintenance cycles.
- Local Offline Storage: Securely retains up to 2,800 historical data records with support for auto-retransmission to eliminate missing network packets.
Product Overview
The system functions as an industrial spot leakage detection node explicitly engineered to identify the early presence of water or conductive fluids at a precise pinpoint location before infrastructure damage occurs. Beyond localized fluid checking, the unit features built-in environmental sensing arrays that continuously measure and log ambient relative humidity and temperature variables. Equipped with a certified IP67 waterproof and UV-resistant chassis, this transceiver is fully optimized to survive severe indoor deployments and demanding outdoor field exposures over long periods.
Driven by an ultra-low-power radio architecture, the device relies on a high-capacity lithium battery system to achieve up to 10 years of operational service life without hardware intervention. To eliminate data gaps, the internal chip embeds an offline storage cache that retains up to 2,800 historical data records for automated retransmission if the upstream network goes offline.
