About This

• DUAL-MODE HIGH & LOW WATER LEVEL DETECTION – Switch Effortlessly to Match Your Needs Tired of one-size-fits-all sensors? This smart water level alarm lets you instantly toggle between HIGH water alert mode and LOW water alert mode . Use it as a sump pump failure alarm, sewage backup detector, tank overflow guard, or well dry-run protector — one device covers all scenarios, no tools required.
• BUILT-IN BACKUP BATTERY – Keeps Protecting You Even When the Power Goes Out The worst floods and water emergencies almost always knock out the power first — and that's exactly when you need your alarm the most. That's why this sensor features a built-in rechargeable backup battery that automatically activates the instant your main power is cut. No manual switching, no setup — it kicks in silently and seamlessly, so your 110dB alarm, strobe light, and app notifications keep working through blackouts, storms, and power outages. When grid power is restored, the battery recharges automatically. True protection that never sleeps.
• TRIPLE-LAYER ALARM SYSTEM – 110dB Siren + Red Strobe Light + Instant App Push Notification When water reaches a critical level, this alarm fires on three fronts simultaneously: a piercing 110dB buzzer audible from over 100 feet away, a flashing red LED strobe light for instant visual warning even in noisy environments, and an instant push notification to your smartphone via the Smart Life App (No subscription fee)— so you're alerted the second something goes wrong, even when you're away from home.
• SMART APP CONTROL WITH MULTI-USER SHARING – Monitor Together with Up to 20 Family Members Connect via Wi-Fi and the Smart Life app to monitor water levels in real time from anywhere. The device sharing feature allows up to 20 users to receive simultaneous alerts — share access with family members, neighbors, or building managers for collaborative monitoring and instant group response. Perfect for vacation rental properties, shared buildings, and multi-person households.
• IP65 WATERPROOF RATED – Built TOUGH for Indoor & Outdoor Use in Any Weather Rated IP65 weatherproof, this water sensor withstands heavy rain, splashing water, and outdoor humidity without failure. Install it confidently in basements, crawl spaces, garages, bathrooms, utility rooms, patios, garden ponds, swimming pools, or any exposed outdoor location. The durable housing performs reliably through all seasons — rain, storm, or freeze.
• WIDE APPLICATION SCENARIOS – The Last Water Alarm You'll Ever Need to Buy This versatile water level detector works across virtually any liquid-monitoring need: sump pit overflow, septic tank high water, aquarium water level, hot water heater leak, irrigation reservoir, flood detection, industrial water tanks, agricultural water storage, and more. Whether you're a homeowner, farmer, facility manager, or DIY enthusiast — this sensor adapts to protect what matters most.
