Product Details
R121-1 drone proximity sensor can detect obstacle distance to drone during flying. It uses 77GHz-81GHz millimeter wave radar to realize the smart drone collision avoidance and safety secure.
The radar has advantages of high precision, small body, high sensitive, light weight, easy for integration and stable performance. This product can distinguish whether there’s obstacle ahead or not by forward sending fan-shaped 79GHz electromagnetic wave and dealing with the returned signals. It will send back the relative distance, speed and angle data between obstacles and radar to make the drone keep away from obstacles and ensure its safe working.

FAQ
Q: What is the detect range of R121-1? Why the minimum detect distance is 1.5m?
A: The drone obstacle detection range is 1.5~120m. Considering about the drone wing length, it needs to stop while the distance between drone and obstacle is less than 1.5m. So the minimum detection distance is 1.5m.
Q: Don’t know how to calculate the best install angle, is there a recommended angle?
A: According to the installation angle recommendation and the test result, we suggest flight controller be inclined 12°upward for installation.
Q: Will the radar have data output if it hasn’t detected any obstacles?
A: Radar outputs data in real time. While radar hasn’t detected any obstacle or the obstacle distance longer than 120m, it outputs data 0; While radar detected obstacle successfully, it outputs the actual distance of obstacle.
