To solve the problem that the water quality environment is difficult to detect in real time, a set of water quality detection system based on microcontroller STM32 is designed and developed by using the way of sending real-time detection by the lower computer and receiving and processing data by the upper computer. pH value detection module, DS18B20 temperature sensor module and TDS water quality detection module are added. It can detect water temperature, pH value in water, TDS water quality and GPS positioning data collection points in real time, and combine with the corresponding Web client and mobile APP to send and receive wireless data remotely, which is convenient and fast and improves the detection efficiency.

Key words: water temperature measurement, pH value measurement, TDS water quality measurement, remote wireless transceiver, GPS positioning
