WANG Li, ZHANG Shaopeng, WANG Wei

Abstract: This paper designs a water quality monitoring system with STC89C52 microcontroller as the core controller. The system combines sensor technology, single-chip control technology, LCD display module and alarm circuit to monitor water quality in real time, and the overall design block diagram of the system is given. Through Protues software simulation and hardware testing, it is proved that the designed system can monitor the temperature in real time and display it on the LCD display; when the temperature exceeds the set threshold, the system can automatically alarm.

Keywords: Microcontroller, STC89C52, Temperature sensor, LCD display, Alarm circuit
