45 The address of the EC K1 sensor is 11
46
47 The query data command is 11 03 00 00 00 02 C6 9B
48
49 For example, the returned data is 11 03 04 02 AE 01 64 8B D0, 02 AE is converted to decimal 686,  K=1, EC: 686uS/cm

81 The address of the dissolved oxygen sensor is 14
82
83 The query data command is 14 03 00 14 00 01 C6 CB
84
85 After the query, 7 bytes will be returned. For example, the returned data is 14 03 02 03 78 B5 55. 03 78 is the value of dissolved oxygen.
86
87 Converted to decimal, it is 888. Add two decimal places to get the actual value. 03 78 means the current dissolved oxygen is 8.88mg/L
