Someone can help?

Try putting this after the line,

line = ser.readline().decode('utf-8').rstrip()

number = [int (s) for s in line.split () if s.isdigit ()]
if number [0] > 50 :
	print ('ATTENTION!!!')
else : 
	print ('LOW!!!')

The whole thing should look like this. You can copy and paste.

#!/usr/bin/env python3
import serial
ser = serial.Serial('/dev/ttyUSB0', 115200, timeout=1)
ser.flush()
while True:
	if ser.in_waiting > 0:
		line = ser.readline().decode('utf-8').rstrip()
		number = [int (s) for s in line.split () if s.isdigit ()]
		if number [0] > 50 :
			print ('ATTENTION!!!')
		else : 
			print ('LOW!!!')
		print(line)

one more doubt : i need to replace print for this command: sudo python smartblinds-diy/control.py -t AA:74:56:99:71:AE -c move_down , but when i execute this command from root it works but inside this python script dont : pi@lima-raspberrypi:~ $ python receive_serial_data_from_usb01.py
File "receive_serial_data_from_usb01.py", line 13
sudo python smartblinds-diy/control.py -t DA:74:56:99:71:DE -c move_down
