The UAV-H31-1 utilizes Frequency-Modulated Continuous Wave (FMCW) radar technology in the 77–81GHz band to provide highly accurate, non-contact distance and height measurements. This principle allows it to distinguish between multiple targets, such as crop canopies and ground surfaces simultaneously, making it ideal for precision agriculture and terrain-following applications.
Engineered for integration into unmanned aerial systems, the sensor outputs processed height data via a simple UART serial protocol. Its compact, IP67-sealed aluminum housing protects the internal RF circuitry from moisture, dust, and mechanical vibration, ensuring stable performance across the full industrial temperature range from -40°C to +85°C.
