DC 4.5-5.5V DIY Ultrasonic Ranging Electronic Kit 51 STC Single-chip LED Ultrasonic Rangefinder 5CM-3M Radar Alarm DC 5.5*2.1MM

Product Features: 1. Ranging range 5cm-3m: The highest accuracy can reach the distance of objects within a range of 3m, meeting the measurement needs of various spaces 2. Three digit digital display: The measured distance is displayed on the digital display (the displayed distance is in "M" units) 3. It has functions such as buzzer alarm, automatic voice broadcast, and automatic distance broadcast 4. The power supply can be either DC socket power supply or battery box power supply. Choose one from the two when using, do not supply power at the same time 5. Welding is convenient and easy to operate, making it very suitable for DIY enthusiasts, hands-on projects, and obstacle detection applications

Product Parameters: Supply voltage: DC4.5-5.5V Ranging range: 5CM-3M Display mode: LED digital tube display Power supply method: DC 5V or 3 1.5V AA batteries (batteries not included in shipment) Power supply interface: DC 5.5 * 2.1MM PCB board size: 78 * 67mm Function (Instructions for Use): After powering on, press the power self-locking switch, and the system will start measuring distance. The measured distance will be displayed on the digital display (in meters), and voice will be automatically broadcasted. When there is a rapid and significant change in the measured distance, the distance will also be automatically reported. Introduction to the functions of the four buttons: The leftmost "-" is used to reduce the alarm distance. Pressing it on the settings interface is only effective, and pressing it normally is ineffective; +"is used to increase the alarm distance. Pressing it after entering the settings interface is only effective, and pressing it normally is invalid; SET "is the setting key. Press it once to enter the setting interface.+and - are only valid. Press it again to exit the setting interface. The "horn symbol" on the far right is the manual voice playback button, which will play the current distance measurement data once pressed.
