HU-091 Ultrasonic Radar Scanner DIY Kit
Build your own radar system from scratch with the HU-091 Ultrasonic Radar Scanner DIY Kit. Powered by USB DC 5V, this hands-on electronics kit combines a servo motor, ultrasonic distance sensor, and a vivid 2.4-inch LCD display to create a fully functional 0–180° scanning radar — perfect for students, makers, and coding beginners alike.
Key Features
- 0–180° Servo Scanning: A servo motor sweeps the ultrasonic module across a full 180° arc, measuring the angle and distance to any detected object in real time.
- Real-Time LCD Sector Display: Targets detected within 2 cm to 3 m are shown as red dots on a dynamic sector diagram right on the built-in 2.4-inch LCD screen — visually striking and immediately intuitive.
- HXFB Drag-and-Drop Graphical Programming: Includes compatibility with HXFB graphical programming software, making it ideal for beginners learning to code without needing to write a single line of syntax.
- PC Radar Display Software: Connect to a Windows 64-bit PC to view a dynamic radar sector diagram on your monitor, converting distance data into a live graphical interface.
- Full DIY Assembly: Every component is included — assemble, wire, and program it yourself to develop practical electronics and problem-solving skills.
- Low Power Consumption: Runs on standard USB 5V power with a maximum operating current of approximately 150 mA.
