Description
About Jiyi Obstacle Avoidance Radar for Agriculture Drones
The Jiyi UAV-R21 Obstacle Avoidance Radar is an advanced millimeter-wave radar sensor developed by Microbrain Intelligent Technology Co., Ltd. This compact, lightweight radar sensor provides reliable obstacle detection for drones by emitting 77GHz sector electromagnetic waves. The system then processes the echo signal and relays the distance, speed, and azimuth of obstacles. Designed to enhance safety, it helps drones avoid obstacles and ensures stable operation even in complex environments like agriculture.
Key Features:
- High Sensitivity: Detects small obstacles such as electric wires, small trees, and telephone poles.
- Long Detection Distance: Effective up to 20 meters.
- Fast and Stable Signal Transmission: Provides accurate real-time data for quick decision-making.
- All-Weather Performance: Functions effectively in strong light, fog, dust, wind, or nighttime conditions.
- Environmental Adaptability: Operates in extreme temperatures from -20°C to +85°C.

- Power Consumption: 3.0W @ 25°C
- Working Voltage: 9-28V
- Output Interface: CAN protocol, baud rate of 1Mbps
- Weight: 109.5g (with cable)
- Waterproof Rating: IP67
Installation Guide:
- Location: Ensure the radar’s azimuth is ±17° and the elevation is ±3° with no obstacles within the field of view (FOV).
- Direction: The radar antenna, located at the back, must face the front of the drone, with the arrow on the back pointing upward.
- Angle: Install at a tilt of 8°-12°, based on the maximum downward tilt angle of the drone’s flight.
- Stability: The more stable the drone platform, the less the radar beam will wave in the pitch direction.
Usage Instructions:
- Pin Definition: Red is for power, black is ground, and yellow is the pulse signal output.
- Data Analysis: The radar will output the Y-coordinate of the nearest detected obstacle, allowing the drone to take corrective action in real time.
Precautions:
- Handle the radar with care, avoiding static electricity and physical damage.
- Clean the radar cover with a soft damp cloth and dry it naturally before use.
- Ensure the radar is installed in its original condition and avoid disassembly.
Package Includes:
- 1 x Jiyi UAV-R21 Obstacle Avoidance Radar
