GroupCore Acoustic 24H Online Panoramic Intelligent-Perception Micro-Leak Monitor

The “Micro-Leak Sentinel” Product Solution

I. Industry Background and Pain Points

As the construction of new infrastructure, the digital economy, smart cities, the industrial internet, and low-carbon campuses continues to deepen, critical scenarios such as data centers, power distribution facilities, storage spaces, and underground utility tunnels are placing unprecedented demands on operational safety. Water seepage, condensation, pipe damage, roof seepage, and liquid accumulation at equipment bases are concealed, sudden in onset, and cascading in impact—if not detected in time, they can directly lead to server downtime, short circuits in power distribution equipment, cargo damage, moisture damage to archives, damage to experimental equipment, and even structural damage to buildings and production interruption.

Traditional seepage monitoring methods, however, have long remained at the stage of “manual inspection + post-event disposal,” with clear shortcomings:

• Manual inspection can hardly cover nighttime, holidays, or unattended areas;

• Traditional water immersion ropes / metal probes / ordinary humidity sensors mostly provide a binary “water / no water” judgment, and often trigger an alarm only after standing water has reached a certain level;

• Traditional wired systems have high construction costs and are difficult to retrofit, making them hard to replicate at scale;

• Consumer-grade water immersion products are oriented toward home scenarios and lack engineering O&M and multi-point management capabilities;

• Professional pipeline-network monitoring equipment requires long build-out cycles and large investment, making it difficult to flexibly deploy down to point-level scenarios such as machine rooms and laboratories.

The market urgently needs a domestically developed seepage monitoring product that can be deployed quickly, replicated across multiple points, at controllable cost, with sensitive-material advantages and digital management capabilities. This is precisely the origin of GroupCore Acoustic’s “Micro-Leak Monitor.”

II. Product Positioning

The GroupCore Acoustic 24H Online Panoramic Intelligent-Perception Micro-Leak Monitor (the “Micro-Leak Sentinel”) is a wireless intelligent seepage monitoring and early-warning system built around a composite hydrogel sensing material. The product deeply integrates material innovation, hardware engineering, wireless communication, a data platform, and scenario services to form an industrialization closed loop of “material—device—system—platform—application,” driving seepage monitoring from “manual inspection and post-event disposal” to a comprehensive upgrade toward “material sensing, real-time early warning, and proactive O&M.”

Compared with conventional point-type solutions that rely on “water-level flooding” to trigger an alarm, the core differentiation of this product lies in its ability to perceive local humidity anomalies, water vapor accumulation, and dampness-recurrence trends in the vicinity of the monitored surface before obvious standing water forms, enabling early discovery of slow seepage, concealed leaks, and early-stage dampness.

III. Core Technologies

3.1 Composite Hydrogel Sensing Material (Technical Moat)

The core moat of the product lies in the composite ionic liquid hydrogel sensing unit. Based on a multi-bond network strategy and prepared by a one-pot method, this material offers the following engineering advantages:

• High stretchability, self-healing capability, high transparency, high strength and toughness, anti-freezing performance, easy recyclability, and low cost, resolving key scientific issues of polymer humidity-sensing materials in reuse, recycling, and multifunctionalization;

• Leveraging the material’s water-absorption response and ionic conductivity to produce significant electrical signal changes upon contact with water or exposure to a humid environment;

• Linear response with drift-free stability: it maintains a good linear response across the high-humidity range (20–100% RH), overcoming the common weakness of conventional humidity sensors, which drift easily in high-temperature, high-humidity environments;

• Conforms to complex surfaces, producing more stable responses to trace water seepage, localized dampness, and irregular contact areas.

The material is both a technical moat and a key lever for subsequent consumable-based, modular, and differentiated competition, effectively avoiding the industry predicament in which “a material performs well yet is difficult to productize.”

3.2 Structural Design of the Hydrogel Sensing Unit

The hydrogel material is fabricated into strip-shaped transparent sensing units, balancing material exposure, signal acquisition, maintenance and replacement, and product assembly, while facilitating standardized mass production. The units are installed in the sensing area at the bottom of the equipment and make full contact with the monitoring area, ensuring sensing sensitivity and consistency.

3.3 Low-Power Acquisition and Anomaly Recognition

The device continuously acquires the resistance, conductance, and related electrical signals of the hydrogel sensing material, and combines baseline calibration, threshold decision, continuous trigger confirmation, and trend analysis to significantly reduce false alarms and missed detections. Threshold-setting strategies differ across scenarios; the product employs AI small-sample analysis to adaptively establish the optimal threshold.

3.4 Wireless Networking and Device–Edge–Cloud Collaboration

Integrating device ID, wireless transmission, data caching, alarm logging, remote push notification, and platform management functions, it forms a complete chain of “material sensing—signal acquisition—edge decision—wireless transmission—cloud management—O&M service,” supporting large-scale, multi-point distributed deployment.

IV. Product Composition and System Architecture

The product is available in two forms—W1 (mains-powered) and W2 (battery-powered)—flexibly adapting to different site conditions.

V. Six Major Product Values

5.1 Wireless Deployment · Multi-Channel Coordination

It forms a product system of “sensing node + communication gateway + host computer / cloud platform + O&M service,” supporting multi-channel coordination across Bluetooth, WiFi, and radio frequency (LoRa) to cover different deployment needs:

5.2 All-Weather Online · Traceable Data

Through the cloud platform, it builds an edge–cloud management model of “monitoring—alarming—recording—tracing”: normal data is synchronized in batches while alarm events are pushed instantly, with support for logs, reports, accountability tracing, and Excel export, so that every anomaly is verifiable.

5.3 Early Perception · Material First

Using a humidity-sensitive material as the sensing medium, it discovers seepage in advance—triggering an early warning already at the stage of dampness recurrence, slow seepage, or concealed humidity anomalies, nipping incidents in the bud.

5.4 Multi-Point Coordination · Multi-Modal Anti-Interference

Reliable wireless transmission protocols ensure the accuracy of data transmission. Under good network conditions, the data transmission rate can reach several hundred Mbps (LAN channel), and the wireless coverage range can reach tens of meters; in actual use, the data transmission failure rate is below 1%.

5.5 Intelligent Decision · High Integration, Low Power

The data acquisition module adopts a highly integrated, low-power design (based on an ADS-series analog-to-digital converter and a PGA, combined with an ESP32 main controller), dispensing with conventional data acquisition cards and, after filtering and deduplication, being better suited to long-term monitoring. The core algorithms include:

• Baseline calibration: eliminates interference in judgment caused by initial resistance differences among probes;

• ID management: with multiple nodes uploading simultaneously, specific points can be located rapidly; a single host computer can manage multi-device, multi-point data;

• Anomaly debouncing: an alarm is triggered only after multiple consecutive out-of-threshold readings, effectively reducing false alarms.

5.6 Proactive Early Warning · Strong Software Compatibility

Both the host computer software and the mobile control software are independently developed, offering diverse control functions such as alarm threshold setting, data query, and analysis. The interface is simple and easy to use; users can monitor temperature, humidity, and early-warning data from a mobile phone or computer at any time and take immediate measures. The software supports multiple operating systems and multiple devices, with good compatibility.

VI. Technical Parameters

Notes: (1) The “response time < 1 s” figure is to be qualified—whether it denotes the electrical response upon contact with water or the time required to detect a leak event (see the appendix, Section 3, item 3). (2) The “±2–3% RH” measurement accuracy is quoted without test conditions (temperature range, humidity segment, and reference instrument). (3) The waterproofing specification is quoted without an IP rating. (4) The 3.7 V lithium battery is quoted without capacity or operating endurance, on which the “24H online” claim directly depends. (5) The LoRa operating frequency band is to be specified (see the appendix, Section 3, item 8). (6) Transmission rate and coverage figures in Section 5.4 are channel-dependent, as detailed in the appendix, Section 3, item 4.

VII. Typical Application Scenarios

X. Installation and Deployment

Selection of installation locations: Sensors should be deployed preferentially at key risk points prone to water seepage, dampness recurrence, or water vapor accumulation. For multi-point systems, point density should be determined in light of building structure, pipeline routing, equipment criticality, and inspection experience. Typical points include:

• Wall corners, wall bases, expansion joints, construction joints, and the inner walls of underground spaces

• Pipe interfaces, valves, flanges, joints, and wall penetrations

• Equipment bases, equipment foundations, and the vicinity of water pumps and water tanks

• The vicinity of distribution cabinets, low-voltage cabinets, server racks, and control equipment

• Air conditioning condensate pipes, drainage trenches, floor depressions, and water collection areas

• The vicinity of laboratory water-cooled equipment, liquid storage vessels, and liquid piping

Installation methods:

• Contact installation: suited to floor depressions, beneath piping, equipment bases, and locations where water droplets may appear;

• Near-field off-surface installation: suited to walls, pipe roots, equipment foundations, pipe shafts, and positions where direct contact is inconvenient.

Avoidance requirements: Installation points must avoid areas with direct airflow and abrupt temperature changes, must not be blocked by debris, and must protect the sensitive material from contaminants; wireless devices should be kept away from large metal surfaces, with antennas adjusted as needed; key points should be numbered and installation records retained.
