The design STC89LE516AD microcontroller as the core processor; collected by TDS sensor is measuring target TDS value, combined with the temperature sensor DS18B20 collecting temperature value on TDS compensation calibration; using GE_TS type turbidity sensor to obtain the measured water turbidity value through the microcontroller chip AD conversion module; the LCD1602 LCD display module is measuring the TDS value of water, turbidity and other information; and the capture of the TDS value, turbidity values were compared with the limit value set by the system, when the limit is reached when the buzzer and the LED lamp are sound and light tips, and set the upper limit value can be adjusted through the key.
