The LC-604 Basement Water Sensor WiFi is a professional low-lying water monitoring device engineered exclusively for basement flood prevention and building property safety management. Tailored to the high humidity, poor ventilation, and long-term dark environment of building basements, underground garages and commercial complex underground spaces, this smart WiFi water sensor adopts high-sensitivity anti-corrosion detection probes and enhanced wall-penetrating WiFi technology. It achieves 24/7 unattended real-time monitoring of groundwater backflow, pipeline leakage, rainwater accumulation and equipment condensate seepage. Once water presence is detected, it triggers instant on-site sound-light alarms and mobile APP remote push alerts, helping property teams eliminate hidden water damage risks in the earliest stage. Effectively preventing basement floor corrosion, wall mildew, facility damage and property economic losses. Supporting standardized finished product supply and personalized custom development, it fully meets the diversified flood monitoring needs of residential, commercial and industrial building basements.

Product Features
Basement-Specific Anti-humidity & Anti-false Alarm Design Optimized for long-term humid and dark basement environments, equipped with intelligent algorithm filtering system. It accurately distinguishes air humidity, wall condensation and actual water accumulation, completely solving the false alarm problem of ordinary sensors in high-humidity underground spaces, ensuring stable and accurate long-term monitoring.
Enhanced Wall-penetrating WiFi Remote Connection
Adopts upgraded 2.4G high-gain WiFi module with strong anti-interference and wall-penetrating capabilities. It stably transmits signals through thick basement walls and reinforced concrete structures, no gateway required. Realizes cloud data synchronization and remote real-time alert push, supporting unattended remote monitoring of closed underground spaces.
High-precision Full Coverage Water Detection
Supports ultra-shallow water layer detection and large-area floor flood monitoring, capable of capturing tiny seepage of underground pipelines, slow rainwater backflow and local water accumulation in low-lying corners. It covers all hidden flood-prone blind areas in basements to achieve comprehensive risk prevention.
Industrial Waterproof & Long-term Standby Performance
Features IP67 full waterproof and dustproof grade, with corrosion-resistant and aging-resistant probe and shell materials, adapting to long-term damp and dark basement working conditions. Equipped with ultra-low power consumption chip, it supports ultra-long battery standby, reducing frequent maintenance in hard-to-reach underground spaces.
Dual Alarm & Easy Batch Deployment
Integrated high-brightness flash LED and 100dB adjustable buzzer for clear on-site warning in dark basements. Compact and lightweight structure supports flexible placement and fixed installation, suitable for rapid batch layout in large-scale commercial building basements and underground garages.
Working Principle
The LC-604 WiFi basement water sensor adopts reliable conductive liquid contact sensing principle optimized for underground environments. The precision anti-corrosion dual probes keep real-time detection of the basement floor and low-lying areas. When water accumulation, pipeline leakage or groundwater backflow occurs and covers the probe, the internal circuit forms a conductive loop, generating real-time resistance signal changes. The built-in high-speed MCU chip filters humidity interference and invalid signals through professional algorithms to confirm effective water hazard signals. Immediately, the device activates local sound-light alarm, and uploads water occurrence position, time and device status data to the cloud platform via WiFi. Users receive instant mobile APP remote alerts for timely drainage and maintenance. After the accumulated water is completely cleaned and the probe dries out, the sensor will automatically reset and resume 24-hour cyclic monitoring.

Application Fields
The LC-604 basement water sensor WiFi is widely used in building property and commercial complex underground scenario monitoring, focusing on solving various water hazard problems in underground spaces. It covers residential building basements, commercial shopping mall underground floors, office building underground equipment rooms, hotel underground auxiliary areas, community underground parking lots, and basement fire control & HVAC pipeline areas. It effectively monitors hidden risks such as seasonal rainwater backflow, underground pipeline burst leakage, equipment condensate water accumulation, and foundation seepage, providing intelligent safety monitoring guarantees for property daily operation management, avoiding basement wall peeling, equipment corrosion, parking facility damage and large-scale water flooding accidents.

Installation Method
The LC-604 basement water sensor supports tool-free, non-destructive and rapid installation, perfectly adapting to large-scale deployment of building basement scenarios. Firstly, install supporting batteries to power on the device, then complete WiFi network configuration and mobile APP binding according to the operation guide. Place the high-sensitivity detection probe flat on basement low-lying ground, pipeline passage bottoms, equipment room floors and other water-prone areas. Fix the sensor main unit on dry and ventilated wall surfaces to avoid long-term water soaking and signal shielding. After successful networking, the device automatically enters 24-hour uninterrupted intelligent monitoring state. The whole installation process takes only 2-3 minutes without professional wiring and construction, convenient for unified layout, later position adjustment and daily maintenance of building basement monitoring points.
