The Dragino LWL03A is a LoRaWAN rope-type water leak controller for monitoring long runs such as data-center floors, pipe chases, and basements. Lay the sensing cable on the ground and the controller reports a leak event the moment water touches any point along the cable, with periodic status every 2 hours.

Key specifications

• None-position sensing rope: detects water anywhere along the cable run
• 8500 mAh Li-SOCl2 battery for up to 10 years of operation
• 1 m water-leak cable included; extendable with DR-WLN cable segments (1/5/10 m)
• LoRaWAN v1.0.3 Class A; counts leak events and measures last leak duration
• Remote configuration via LoRaWAN downlink; AT commands for parameter changes
• Operating temperature -40 to 85°C; firmware upgradable via program port

This US915 variant works with standard LoRaWAN gateways and network servers for large-area leak protection.
