Stop Leaks, Avoid Further Damage, the WS303, a mini water leak detection sensor that detects the presence of leaks and raises alarms locally and remotely. With low power consumption, it can operate for 5 years on a single battery. It's ideal for smart offices, buildings, houses, etc. WS303 will sound an alarm and send a remote alert when water leakage occurs. The WS303 sensor uses water conductivity to detect a minimum water level of 0.5 mm by forming a circuit with two little metal probes. (Other conductive liquids are also supported). Milesight D2D (Device to Device) communication protocol featuring LoRa® enables the communication among different Milesight LoRaWAN® node devices without a LoRaWAN® gateway.\n\u003cbr\u003e\u003cbr\u003e\nPerfect for smart buildings, smart city deployments or industrial use-cases.\n\u003cbr\u003e\u003cbr\u003e\nNeed help selecting the right IoT solution?\n\u003cbr\u003e\u003cbr\u003e\nGo Wireless NZ now offers a full consultation service through its subsidiary company \u003cb\u003e\u003ca href=\"https:\/\/www.scopious.co.nz\/\" target='_new\"'\u003eScopious IoT Ltd\u003c\/a\u003e\u003c\/b\u003e to help you to start building your IoT network today.
