In demanding industrial and inspection scenarios, drone operators face one consistent challenge — ensuring safe and reliable flight in cluttered or low-visibility environments. DJI addresses this challenge head-on with DJI Matrice 4 Obstacle Sensing Module, a powerful add-on that combines rotating LiDAR and millimeter-wave radar technologies to deliver all-direction obstacle awareness, even in the most intricate conditions.
At the heart of DJI Matrice 4 Obstacle Sensing Module lies DJI’s most advanced detection system yet. By fusing LiDAR-based 3D scanning with millimeter-wave radar, the module provides a detailed, real-time understanding of the drone’s surroundings.
This unique combination enables:
Omnidirectional obstacle avoidance — including horizontal, upward, and downward detection for complete 360° coverage.
Ultra-precise sensing — capable of detecting obstacles as thin as 12 mm, such as power lines and cables that typically go unnoticed by standard sensors.
Enhanced performance in low light — thanks to LiDAR’s ability to function independently of lighting conditions, ensuring consistent safety in day or night missions.
The module is designed specifically for the DJI Matrice 4 Series, providing perfect integration and consistent performance across inspection, mapping, and emergency response missions.
From dense urban environments to intricate power distribution networks, this module ensures safe navigation where traditional vision systems may fail. It excels in:
Power grid and substation inspections — detecting wires, poles, and transformers with millimeter-level accuracy.
Urban infrastructure surveys — navigating tight spaces and tall structures with confidence.
Emergency response and search missions — maintaining full situational awareness even in smoke, fog, or low-visibility conditions.
With obstacle detection effective at speeds up to 15 m/s, operators can fly faster and safer — reducing downtime and the need for manual oversight during critical missions.
Engineered for durability, DJI Matrice 4 Obstacle Sensing Module features IP55-rated protection, making it resistant to dust and water exposure. This ensures reliability even in challenging outdoor conditions such as rain or dust-filled environments.
It also includes a mounting bracket for quick and secure installation on the Matrice 4 Series aircraft. When paired with DJI’s integrated downward radar sensing, the system achieves full 360° environmental awareness, significantly enhancing flight safety and autonomy.
To ensure optimal performance and safe operation, here are some recommendations:
Power off the aircraft before installing or removing the module.
Secure installation by tightening all screws using the provided hex screwdriver.
Update firmware and activate devices after installation according to DJI app prompts.
Pre-flight checks — verify the module is functioning correctly and fly under favorable GNSS and weather conditions.
Note: Obstacle sensing may be affected by certain factors such as fog, rain, snow, or dust; the material and shape of obstacles; or the presence of objects smaller than 12 mm in diameter. Additionally, radar functionality may be restricted in certain countries due to policy regulations.
When not in use, always attach the protective cover to prevent surface wear or damage to precision components.
DJI Matrice 4 Obstacle Sensing Module represents a major step forward in drone flight safety and environmental perception. By bridging the gap between visual and radar-based obstacle detection, it empowers operators to perform BVLOS (Beyond Visual Line of Sight) missions with greater confidence and efficiency.
For professionals conducting inspections, mapping, or emergency operations in complex spaces, this module transforms the Matrice 4 into a fully aware, safety-optimized aerial platform — ensuring every flight is as safe as it is productive.
