The sensor is connected to an external power supply 12V - 1A.
The program was coded in Python and it is quite simple.
How can i check that the sensor is working ?

this is the python code:
Code: Select all
#!/usr/bin/python
import serial
import time
ser = serial.Serial(port='/dev/ttyUSB0', baudrate=19200, parity=serial.PARITY_NONE, stopbits=serial.STOPBITS_ONE, bytesize=serial.EIGHTBITS, timeout=1)
print("connected to: " + ser.portstr)
req = "\x55\xaa\x11\x00\x02\x12"
while True:
print "sending request to sensor"
bytes_written = ser.write(req)
valueFromSensor = ser.read(8)
print [ord[x] for x in valueFromSensor]
time.sleep(5)
ser.close()
