Winext AN-204B Spot Water Leak Detector with LoRaWAN wireless sensor probe

Product Description

The Winext AN-204B is a wireless spot water leak detector designed for LoRaWAN-based remote monitoring. It uses the electrical conductivity of water to detect a leak: when water contacts the sensing electrodes, conductivity changes and the detector initiates an immediate alarm event. A built-in omnidirectional antenna supports convenient installation and reliable wireless coverage.

Applications

Suitable for water-damage protection in communication base stations, precision machine rooms, libraries, exhibition halls, museums and other critical facilities.

Product Features

  1. Detects spot water leakage using the electrical conductivity of liquids; contact with water causes the sensing electrodes to conduct and initiates an immediate alarm event.
  2. Communicates wirelessly over LoRaWAN for long-range remote leak monitoring.
  3. Supports CN470, EU868, US915, AS923 and AU915 regional frequency bands.
  4. Provides up to 21dBm transmit power with -141dBm receive sensitivity at SF12 and a 300bps to 5.4Kbps transmission rate.
  5. Uses a built-in long-life 3.6V 4000mAh Li-SOCl₂ battery with up to 3 years of service life.
  6. IP65 construction and a -10°C to +50°C operating range suit critical facilities requiring water-damage protection.
