Sonoff - Zigbee water leakage sensor

Description

Visit Sonoff Zigbee SNZB-05P water leakage sensor is a compact, reliable device designed to quickly detect water ingress. Thanks to its Zigbee 3.0It integrates perfectly into a local home automation system based on a Raspberry Pi with a Zigbee dongle.

Optimized design and detection

• It features high probes which detect water levels from 0.5 mmeven on metal surfaces without false tripping.
• Sa concave surface collects drips, detecting slow or dripping leaks at first contact with a small volume.

Autonomy and robustness for the home

• Powered by a battery CR2477offers up to 5 years of autonomyto limit maintenance.
• Its case is certified IP67 water- and dust-resistant, for use under sinks, in laundry rooms or damp cellars.
• The probes are gold-platedThe materials used are UV-resistant to preserve their appearance over time.

Modular cover

A extendable probesold separately, can be easily attached to extend the sensitive area: several probes can be linked together without length limitation, practical for covering a long pipe or a large area.

Reliable & resilient notifications

• The sensor immediately sends an alert via Zigbee as soon as water is detected.
• Local scenes configured on the gateway can trigger an audible alarm even if the main Wi-Fi network is lost.
• In the event of a prolonged leak, it repeats the alert every ten minutes to avoid missed notifications during network disruptions.

Integration with Raspberry Pi for home automation

Once connected to a Zigbee gateway (USB dongle on Raspberry Pi), this sensor becomes a valuable part of the home automation system:

• Immediate alerts on smartphone (via Home Assistant or Node-RED), or visual/audible alarm activation.
• Concrete automation : solenoid valves cut out, fan triggered, switch to "absence" mode if a leak is detected.
• Incident history Knowing when and for how long infiltrations have taken place, to diagnose or make preventive decisions.
• Visual dashboards Real-time monitoring of the status of detected zones on a dedicated interface.
