Xiaomi Smart Water Leak Sensor 2 with Dual Probe Detection
Hidden pipe leaks and accidental basin overflows cause expensive floor damage inside modern apartments. Traditional homeowners often discover standing water only after floor tiles absorb heavy moisture. Therefore, a smart water leak monitoring system protects your home from costly water damage. The Xiaomi Smart Water Leak Flood Detector Sensor 2- SJWS02LM alerts you before small leaks turn into major floods.
Dual Probe Detection for Accurate Leak Alerts
What makes this special is the sensitive dual-probe detection mechanism at the bottom. Thanks to this, the sensor triggers an instant alert when standing water reaches just 0.5mm height. For instance, it detects pipe drips under kitchen sinks before water reaches your wooden cabinet doors. Consequently, homeowners prevent serious furniture ruin inside busy Dhaka apartments.
Smart Bluetooth Gateway Linkage and App Control
Moreover, modern Bluetooth 5.2 connectivity links the sensor with your Mi Home App setup. You connect the device to a Bluetooth Mesh gateway for real-time mobile notifications everywhere. Because of this, you receive instant warning phone alerts while sitting in office meetings or heavy traffic. At the same time, the sensor triggers connected smart alarms to sound urgent local warning chimes.
Waterproof IP67 Rating and Three-Year Battery
Additionally, the compact round body features robust IP67 waterproof protection for wet rooms. Anti-UV corrosion-resistant materials prevent plastic discoloration and hardware damage inside humid bathrooms. On top of that, a single CR2450 button battery keeps the sensor operating continuously for up to 3 years. As a result, you enjoy long-term home security without worrying about frequent battery swaps.
