Abstract
With the rapid development of social economy, excessive discharge of industrial sewage leads to water pollution, and it also affects the quality of domestic water. Therefore, it is necessary to monitor the water quality. A practical and convenient water quality monitoring system is designed in this paper, which is based on the MCU (Micro-programmed Control Unit) and Bluetooth technology. This design takes the Arduino development board based on ATMega328P chip as the core, and uses sensors to collect pH, turbidity, conductivity and water temperature. The measured data is sent to the smart phone via Bluetooth, and abnormal parameters are prompted. The test results show that the system can obtain the water quality parameters in time and accurately, and the overall operation of the system is stable, which is suitable for many occasions of water quality monitoring.
