Key Features

LoRaWAN Class A water leak sensor for long-range, low-power IoT monitoring. IP65-rated housing ensures protection in humid or wet environments. Ultra-low power design supports up to 5 years of battery life for reduced maintenance. External probe detects water presence via contact-based sensing and triggers instant alerts. Supports OTAA/ABP activation for flexible network deployment. Compatible with standard LoRaWAN gateways, including PLANET LCG series.

Technical Context

Designed for distributed leak detection in buildings, basements, data centers, and industrial facilities. Uses LoRaWAN communication for a multi-kilometer range with low bandwidth consumption. Class A operation minimizes energy use by synchronizing uplink transmissions with receive windows. Ideal for large-scale sensor networks where continuous monitoring and battery efficiency are critical. IP65 sealing allows deployment in areas exposed to moisture or accidental water contact.

Installation Notes

Compact sensor: 112 × 88.2 × 32 mm, 141g. Powered by 2 × 3.6V ER14505 AA batteries (not included). Operating range: -20°C to 55°C; storage: -40°C to 85°C; humidity <90% non-condensing. Probe connects externally and should be placed near leak-prone areas (pipes, tanks, appliances). Low battery alert at 3.2V. Typical deployment uses 5–15 minute reporting intervals, depending on battery life requirements.
