Abstract
Water quality testing is to determine the types of pollutants in the water body through the relevant water quality instruments, the concentration of various pollutants and the change trend, and give the evaluation results of water quality status. The realization of comprehensive, timely and accurate water quality testing is the scientific basis for guiding production, and is also the basis for accurately controlling the addition of raw materials and optimizing the production process, which has important practical significance for ensuring the safety of people’s drinking water and the normal water needs of enterprises.
This paper uses STM32 as the main control chip and the sensor to develop a water quality monitoring system. The turbidity sensor is used to detect the turbidity of the water environment, the water temperature of the water environment is detected by the waterproof DS18B20, the PH sensor is used to detect the PH concentration of the water environment, the relevant monitoring value is displayed by the OLED display screen, the water temperature, PH and other threshold values can be set by pressing the button, and the relay can be controlled to perform related work. To achieve the purpose of regulating water environmental pollution, in addition, the WiFi module is also used, which can transmit the detected parameters related to water environment to the mobile phone for display, and can also realize the role of automatic control relay on the mobile phone to regulate the water environment.
The test results show that the system can detect the relevant parameters of water environment well, and automatically control the adjustment of the relevant parameters, so as to avoid the pollution of water environment.
