OEM/ODM Flexibility for Smart Security Integrators
The WLS316 is a compact ZigBee-based water leakage sensor designed for detecting water leaks and sending real-time notifications to mobile apps, ideal for smart home, commercial, and industrial water safety monitoring. OWON offers full-service OEM/ODM support for clients seeking custom branding or system integration: firmware adaptability for ZigBee 3.0 and compatible platforms like ZigBee2MQTT, branding and casing customization for white-label deployment in security or smart home kits, seamless integration with Tuya hubs, open-source controllers, or proprietary water management systems, and support for large-scale deployments with reliable ZigBee mesh networking.
Compliance & Ultra-Low Power Design
This water leakage sensor is engineered to meet global wireless and environmental standards while ensuring extended battery life: compliant with CE and RoHS requirements, operates on a low-power ZigBee 3.0 module (2.4GHz IEEE 802.15.4) for energy efficiency, features an internal PCB antenna with 100m outdoor range for stable connectivity, and is battery-powered (two AAA batteries) with ultra-low power consumption, supporting easy tabletop or wall mounting for hassle-free installation.
Application Scenarios
The WLS316 fits perfectly in a variety of smart water safety and monitoring use cases: water leakage detection in homes (under sinks, near water heaters), commercial spaces (hotels, offices, data centers), and industrial facilities (warehouses, utility rooms), linkage with smart valves or alarms to prevent water damage, OEM add-ons for smart home starter kits or subscription-based security bundles, and integration with ZigBee BMS for automated water safety responses (e.g., shutting off water supply when a leak is detected).
