Introduction:
1.Test result can be displayed through digital tube and serial port at the same time.
2.Digital Tube Display: plug in the ultrasonic module directly, connect to the 5V power supply.
3.Serial Port Output: plug in the ultrasonic module, the port VCC, TX, RX, GND are respectively connected to the 5V, RX, TX, GND of the USB to TTL module. The serial communication baud rate is 9600 and the output format is“D: XXXRN", where XXX represents distance. The display unit is cm.

Tips:
1. The area of the tested object which are flat and have strong reflective ability is not less than 0.5 square meters otherwise it will affect the test results.
2. Effective test distance is 3cm-400cm, over the range may result in data inaccuracy or displaying 000.

Note:
No retail package.
Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.
