DC4.5-5.5V Ultrasonic Ranging STC with LED Measuring Distance 5CM-3M Radar Electronic Kit Features: 1. Measuring range: 5cm-3m: Provides the highest accuracy for measuring distances to objects within a 3m range, meeting the measurement needs of various spaces. 2. Three-digit LED display: The measured distance is displayed on the LED display (distance displayed in "M" units). 3. Features include buzzer alarm, automatic voice broadcast, and automatic distance announcement. 4. Power supply options: DC power jack or battery box. Choose one, do not use both simultaneously. 5. Easy to solder and operate, ideal for DIY enthusiasts, hands-on projects, and obstacle detection applications.

Product Parameters: Power Supply Voltage: DC 4.5-5.5V Measuring Range: 5CM-3M Display Method: LED digital tube display Power Supply: DC 5V or 3 x 1.5V AA batteries (batteries not included) Power Interface: DC 5.5*2.1MM PCB Board Size: 78*67mm

Function (Instructions): After powering on, press the self-locking power switch. The system starts measuring distance, and the measured distance will be displayed on the digital tube (distance displayed in meters). It will also automatically broadcast the distance via voice. When the measured distance changes rapidly and significantly, it will also automatically broadcast the distance. 4 Button Function Introduction: The leftmost "-" button decreases the alarm distance; it is only effective when in the settings interface, otherwise it is ineffective. The "+" button increases the alarm distance; it is only effective when in the settings interface, otherwise it is ineffective. The "SET" button is the settings key; press once to enter the settings interface (the "+" and "-" buttons become effective), press a second time to exit the settings interface. The rightmost "speaker symbol" button is the manual voice playback button; pressing it will play the current distance measurement data. Package Contents: DIY Kit *1
