Even though applying preventive planning, these quality sensors could be affected by several problems, such as the ones listed in Table 1. Thus, a corrective planning is always required to solve these unexpected problems affecting the sensors' reliability.
Main factors affecting the information gathered from water quality sensors
| Cause . | Consequence . |
|---|---|
| Communication problem | Data gap |
| Loss of sensitivity | Flat signal or slow drift down |
| Electronic malfunction | Noise and peaks in the signal |
| Miscalibration of the sensor | Offsets affecting the real value |
