sample of the data received

'10-3-11\t15:28\t23,8\t14,4\t0\r\n', '10-3-11\t15:35\t12,0\t13,5\t8\r\n', '10-3-11\t15:45\t12,0\t14,0\t1\r\n', '10-3-11\t15:46\t12,0\t14,0\t0\r\n', '10-3-11\t15:55\t12,0\t13,5\t11\r\n', '10-3-11\t16:4\t12,0\t13,5\t0\r\n', '10-3-11\t16:5\t23,8\t14,4\t0\r\n', '10-3-11\t16:5\t12,0\t13,5\t2\r\n', '10-3-11\t16:6\t12,0\t13,5\t0\r\n']
