The DJI M350 Drone-Mounted Water Sampler represents a new generation of intelligent water sampling solutions, engineered to redefine efficiency and reliability in hydrological data collection. Integrating a starlight-level night vision camera, a millimeter-grade altitude sensor, and interchangeable sampling containers (available in multiple capacities), this system delivers comprehensive support for diverse water sampling scenarios. A key safety feature is its emergency rope-cutting function, which mitigates the risk of sampler retrieval failure—protecting the drone from entanglement or damage. Capable of altitude-based fixed-point sampling and beyond-visual-range (BVR) operations, the sampler boasts user-friendly installation and intuitive operation, catering to the needs of environmental monitoring teams, research institutions, and water resource management departments alike.

Developed via DJI SDK, the water sampler achieves seamless integration with DJI Matrice 300 RTK and M350 RTK drones. Full operational control is accessible through the DJI Pilot 2 app, enabling unified command of sampling actions (e.g., deployment, retrieval, depth adjustment) alongside real-time drone flight data—streamlining workflow and ensuring operational consistency.

Equipped with a starlight-level night vision camera (0.001 lux minimum illumination), the system provides crystal-clear visual feedback during sampling operations. This enables 24/7 all-weather monitoring, even in low-light or nighttime environments, and facilitates precise beyond-visual-range (BVR) sampling by allowing operators to observe the sampling process remotely—eliminating blind spots and ensuring sample integrity.

The integrated millimeter-grade altitude sensor delivers exceptional positioning accuracy (±0.1mm), precisely calculating the vertical distance between the drone and the water surface. This critical feature prevents accidental contact with the water or underwater obstacles, avoiding flight accidents and ensuring stable sampling operations even in turbulent water conditions.

The system supports fully automated depth-adjustable sampling, with programmable depth settings (0.5m-5m) to meet specific hydrological research needs. This intelligent operation mode eliminates manual intervention, reduces operator workload, and enhances sampling efficiency—ensuring consistent, repeatable results across multiple sampling points.

A built-in emergency rope-cutting system provides proactive protection against drone damage. In the event of entanglement with aquatic plants, debris, or other underwater obstacles, the mechanism triggers automatically to sever the connection rope, safeguarding the drone from being pulled down or damaged—maximizing equipment safety in complex water environments.

Adopting a one-handed quick-release design, the water sampler can be installed or detached from the drone in seconds without additional tools. This modular design enhances portability, simplifies transportation, and allows for rapid replacement of sampling containers—improving field operation efficiency.

Featuring a proprietary water distribution system with anti-backflow valves, the sampler ensures smooth, controlled water collection and prevents cross-contamination between samples. The precision-engineered flow path minimizes sample loss and maintains the original water quality, ensuring the reliability of subsequent laboratory analysis. Every detail of the water distribution process is optimized to meet strict scientific sampling standards.
