Here is the real image:

main.py code:

# main.py -- put your code here!
from pyb import UART 

uart = UART(6, 115200)

while True:
   recv = uart.read(9)
   if len(recv) == 9:
       if recv[0] == 0x59 and recv[1] == 0x59: 
           checksum = 0
           for i in range(0, 8):
               checksum = checksum + recv[i]
           checksum = checksum % 256
           if checksum == recv[8]:
               distance = recv[2] + recv[3] * 256
               strength = recv[4] + recv[5] * 256
               print(distance, strength)   

The result is below, left is distance, unit: cm, and right is strength:
