Designed and Researched on Water-saving Control System for Household Based on STC MCU

A water-saving control system for household based on STC MCU is designed. The sensor of PH value is used to detect PH value of the laundry discharge water. Through the pH value determination test, the PH value of 7.2 is used as the excitation signal. This signal is used to control the work of electromagnetic valve, so that the recyclable wash water is recovered.
