Frequently Asked Questions:

Q1. How does the JIYI Obstacle Avoidance Back Module protect my drone during flight?

Ans. The JIYI Obstacle Avoidance Back Module actively scans the area behind your drone using 24GHz radar technology. When an obstacle is detected within its range, it quickly sends real-time distance data to the drone's flight controller. This allows the flight controller to initiate automated responses such as slowing down, stopping, or performing an avoidance maneuver, effectively preventing collisions, especially when the drone is backing up or operating in tight spaces.

Q2. Can this "back module" be used in conjunction with other JIYI obstacle avoidance sensors?

Ans. Yes, the JIYI Obstacle Avoidance Back Module is designed to complement other JIYI obstacle avoidance sensors, such as front or terrain radars. By integrating multiple modules, drones can achieve comprehensive 360-degree obstacle sensing, significantly enhancing overall flight safety and enabling more complex autonomous operations in diverse and challenging environments. Compatibility is typically seamless with JIYI K++ and KX flight controllers via the CAN bus.

Q3. What makes 24GHz radar technology suitable for drone obstacle avoidance, especially in challenging conditions?

Ans. 24GHz radar technology is highly suitable for drone obstacle avoidance because it utilizes radio waves, which can penetrate conditions that optically-based sensors (like cameras or LiDAR) cannot. This means the JIYI module performs reliably in adverse weather such as fog, heavy rain, dust, and even in complete darkness or bright sunlight. Its strong anti-interference capability ensures consistent and accurate detection, making it ideal for robust outdoor drone operations.
