Q1: What is the core measuring technology of this radar level sensor? How does it compare with ultrasonic sensors?
A1: Our device uses FMCW (Frequency Modulated Continuous Wave) millimeter-wave radar technology. Unlike ultrasonic sensors, it is completely unaffected by temperature, humidity, or air pressure changes. It is also resistant to interference from floating debris, foam, or mud on the water surface. This ensures higher accuracy, stronger stability, and nearly zero maintenance, making it far superior to traditional ultrasonic level sensors.
A2: This is far more than a simple water level sensor. It is a fully integrated monitoring station that combines:
Radar level measurement,
High-definition camera,
Smart IoT telemetry module,
Communication gateway (4G + LoRa self-networking),
Solar-powered supply system.
It provides real-time water level data and on-site images/videos in one solution, addressing multiple monitoring needs at once.
A3: The camera enables remote verification and situational awareness. When an alarm is triggered, operators can immediately check live video or images to confirm if the event is a real flood risk or a false alarm caused by floating objects. This significantly improves decision-making accuracy and reliability in flood early-warning systems.
A4: The sensor features a LoRa self-organizing network module. In areas without 4G/5G coverage, multiple devices automatically form a wireless local network, relaying data hop-by-hop to the nearest gateway with signal. This ensures non-stop data transmission and alarm delivery, even in extreme disaster conditions.
A5: No wiring is needed. The device is solar-powered with MPPT charging and equipped with a high-capacity lithium battery, ensuring long-term autonomous operation even during extended rainy days. The system is designed for easy installation — simply mount it on a pole or bracket, power it on, and it starts monitoring.
A6: Yes. FMCW radar waves can penetrate and reflect off muddy, sandy, or debris-laden surfaces, making it effective for mud-level monitoring. This makes it a reliable solution for flash floods, landslides, and debris flow monitoring, where conventional sensors often fail.
A7: Installation is fast and simple thanks to the integrated design. Communication, sensing, and power modules are pre-assembled. Users only need to fix the device on-site and configure parameters remotely through the platform. Maintenance needs are minimal due to its non-contact measurement and robust IP68 protection.
A8: Data is protected through two mechanisms:
Local storage backup – if the network fails, data is cached and automatically uploaded when connectivity is restored.
Encrypted data transmission – secure protocols prevent unauthorized access or tampering.
This ensures continuous, safe, and reliable water level monitoring.
A9: The device provides dual-link redundancy
Public cellular communication (4G/5G),
LoRa self-organizing mesh network.
If mobile networks are down, the local mesh relays alarm signals to indoor cloud alarm terminals, ensuring that warnings still reach local communities in time.
A10: The cloud-based monitoring platform is not just a dashboard but an intelligent decision support system. Key functions include:
Real-time water level and video monitoring,
Historical data storage and trend analysis,
Multi-level threshold alarms (SMS, phone calls, app notifications),
Remote device management,
Role-based access control.
It transforms raw water level data into actionable insights for flood control, water resource management, and early warning operations.
