JIYI Obstacle Avoidance Back Module - 24GHz Millimeter Wave Rear Protection Radar for Agriculture Drones

The JIYI Obstacle Avoidance Back Module provides agricultural multirotor platforms with complete 360-degree environmental awareness by eliminating the critical rear-facing blind spots during autonomous field missions. Utilizing commercial 24GHz millimeter-wave radar tech, this dedicated rear module sends out constant high-frequency electromagnetic pulses that cut through dense chemical mist, surface dust clouds, and nighttime shadows effortlessly. When your drone travels backwards during automatic pattern sweeps or failsafe returns, this module ensures it slows down and stops well before hitting any unseen obstacles.

Key Features :

• High-Frequency 24GHz Scanning: Penetrates water droplets, floating pesticide spray mist, and field debris to provide reliable echo data day or night.

• Intelligent Blind Spot Defense: Targets the rear flight path during auto-looping, reverse spraying tracks, and autonomous return-to-home protocols.

• Rugged IP67 Sealed Housing: Encased in a chemical-resistant, waterproof enclosure that shields sensitive radar circuitry from corrosive fertilizers.

• Automated Distance Braking: Syncs with the flight controller to actively trigger real-time deceleration and hover overrides when hazards appear within a 30-meter zone.

Use Cases :

• Rear collision protection for heavy-payload agricultural spraying and granular spreading drones during auto-reverse maneuvers.

• Obstacle detection safeguards during automatic, high-speed return-to-home flight profiles on large commercial farms.

• Close-proximity tracking and obstacle buffering over dense orchards, uneven forest boundaries, and complex power line paths.

Technical Specifications :

Compatibility Information :

This rear radar protection unit connects natively to the dedicated sensor bus on JIYI K3A Pro, K++, and K++ V2 autopilot hubs. It configures instantly through the JIYI Agri Assistant mobile application or PC software, running perfectly alongside down-facing terrain-following sensors and front-facing avoidance radars for complete multi-directional protection.

Frequently Ask Questions :

Q1 ) How does the back module radar differentiate from a standard down-facing terrain sensor?

Ans : Down-facing terrain sensors look straight down to calculate the distance to the ground for altitude-following paths. The back module faces horizontally behind the multirotor, scanning the rear airspace for vertical hazards like utility poles, trees, and fences while the drone flies backward.

Q2 ) Will the radar module trigger a false stop if it gets covered in wet chemical spray drift?

Ans : No, the 24GHz millimeter-wave frequency is specifically optimized to ignore micro-particles like water droplets, thin fog, and fertilizer spray. The signal passes right through localized misting to lock onto real, solid structural objects without causing annoying false stops.

Q3 ) Can I mount this back module sensor anywhere on the drone's carbon fiber arms?

Ans : For optimal tracking accuracy, mount the module securely on the rear frame assembly centered along the drone's main axis. Ensure the white front face plate points straight back horizontally, completely clear of descending landing gear columns or low-hanging spray nozzles.

Q4 ) What happens automatically when the radar detects a tree branch behind the drone?

Ans : When an obstacle registers within your preset safety threshold (adjustable from 1.5m to 30m), the module transmits immediate telemetry back to the flight controller. The autopilot overrides manual stick inputs, automatically brakes the drone, and forces a stable hover.

Q5 ) Does the module require regular firmware updates or software calibration?

Ans : The module runs on stable, factory-calibrated internal firmware. However, whenever you perform a major software or firmware update on your JIYI flight controller, you should use the JIYI Agri app to verify the module's sensor status and adjust your braking distances.
