An automated hydroponics system monitors the pH level of a nutrient reservoir to keep it within an optimal range.

The system performs the following actions for a single pH measurement, denoted by HHH:

  • If H<5.8H < 5.8H<5.8, the system activates the alkaline dispenser pump.
  • If H>6.8H > 6.8H>6.8, the system activates the acid dispenser pump.
  • Otherwise, the system logs "pH Stable" and ensures both pumps are turned off.

Draw a flowchart to represent this control process for a single measurement of HHH.
