V2+: Autonomous Liquid Sampling System for DJI M350 RTK Drones

1, Product Overview

The Speedip V2+ UAV-based water sampling system transforms water sample collection into a safe, efficient, and precise aerial mission. Designed for integration with DJI Matrice drones (e.g. M300 / M350 / M400 series), it enables fully automated waypoint sampling via DJI Pilot or via API.

Key specs include:
   • Ultra-lightweight body (~ 540-570 g) made from aerospace-grade materials for minimal added load. 
   • Sampling capacity up to ~ 2 L per mission, via interchangeable containers (e.g. PMMA or stainless steel), enabling surface or depth sampling.
   • Built-in high-precision mm-wave radar with 1 mm resolution for measuring water surface distance and sampling depth with accuracy.
   • Integrated downward-facing wide-angle (≈180° D-FOV) camera with starlight-level low-light performance for situational awareness and monitoring during flight. 
   • Health management features: rope monitoring (tangle detection, grounding detection), emergency rope-cut release function, and real-time data logging.

Advantages & Applications

• Efficiency Boost: Deploys in minutes, supports automated waypoint missions, reducing field sampling time by ~80% vs boat-based/manual methods.

• Safety Improvement: Operators stay remote; no need for boats in difficult or dangerous terrain. Radar + camera feedback enhances situational awareness. 

• Accurate & Reliable Sampling: Precise depth control, stable containers, corrosion-resistant materials & intelligent rope management guard against sample contamination and mechanical failures.

• Lightweight & Low Overhead: Minimal weight footprint allows longer flight time, less energy cost; quick mounting/unmounting streamlines operations.

• Versatile Use Cases: Suitable for environmental monitoring (lakes, rivers, wetlands), maritime/coastal water quality sampling, research & scientific expeditions, emergency response (spill detection etc.). 

In summary, the Speedip V2+ offers an aerial water sampling platform that combines precision, safety, and automation. It is ideal for organizations aiming to modernize their water monitoring workflows, reduce operational risk, and collect high-quality environmental data with less time and cost.
