| |
10.1 | 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 | ||
