As an indispensable material for social development, water pollution is more and more concerned by all sectors of society. Therefore, it is very important to monitor the water quality indicators to protect water resources. Based on the systematic analysis of the current situation of water quality monitoring equipment at home and abroad, this paper monitors, communicates and records four indexes of water quality, namely PH value, dissolved oxygen rate, turbidity and conductivity, aiming at the requirements of on-line water quality monitoring to realize rapid, accurate, real-time, continuous, low cost and automation. Based on the Internet of Things + sensor technology, combined with computers (including software), we have completed a set of relatively mature solutions. The signal measured by the sensor is sent to STM32F103C8T6 single-chip microcomputer for data processing through the conversion circuit, and then the final data is sent to the remote computer through GPRS communication mode and displayed on the upper computer interface.
