| Use Case Number | description | Test procedure and result data | Projected results | Test results |
| 001 | Detecting whether the turbidity sensor is working as expected | Pouring sediment around, the turbidity curve of 1300 is reduced to below 1100 | Turbidity reduction | pass (a bill or inspection etc.) |
| 002 | Detecting whether the ph sensor is working as expected | Adding acidic solution to the surrounding area, the ph curve decreases from 7 to below 6 | Decrease in PH | pass (a bill or inspection etc.) |
| 003 | Detecting whether the temperature sensor is working as expected | Add high temperature aqueous solution to the surrounding area and the temperature changes from 22 to over 30 | temperature rise | pass (a bill or inspection etc.) |
| 004 | Detecting whether the ORP sensor is working as expected | Adding an oxidizing solution to the surrounding area increases ORP | Elevated ORP | pass (a bill or inspection etc.) |
