JIYI Terrain Radar Sensor for K3A Pro Agriculture Drones

This JIYI terrain radar is a 24 GHz millimetre-wave height sensor for agricultural spray drones flying the JIYI K3A Pro flight controller. It scans the ground ahead continuously so the drone can follow changes in terrain and crop height, keeping the nozzles at a constant height for even coverage across the field.

Key features

• FMCW millimetre-wave radar at 24.125 GHz, unaffected by light, for day and night operation
• Measures height from 0.3 to 15 m above ground with 0.05 m accuracy
• 50 Hz output for real-time height correction over slopes and uneven crop canopy
• Wide 6–28 V supply range with a low 1.5 W draw
• Rated for -20 °C to +85 °C with an IP67 housing for field use
