Design Of Water Quality Detector Based On LoRa

With the continuous development of social economy,water pollution is becoming more and more serious.In order to effectively improve the water environment and strengthen the protection of water resources,this paper designs a water quality detector for water quality environmental monitoring.The purpose is to quickly and efficiently obtain water quality information,provide basic data for water quality analysis,and help prevent water pollution and improve the efficiency of water environmental protection.In this paper,the analyses a single board computer is used as the core controller of the water quality detector.Through the Raspberry Pi,several water quality sensors are controlled to collect water quality information such as temperature,PH,turbidity and stored in the equipment.Then,the water quality data are sent to the nearby LoRa base station by LoRa communication technology to realize the function of water quality information collection and transmission.At the same time,considering the scalability requirement of water quality detector,the paper also designs and develops the basic information configuration function of the detector.The main contents of this paper are as follows:(1)In view of the serious phenomenon of water pollution,this paper analyses the development status of water quality detection technology at home and abroad,puts forward the requirements of water quality detection,and determines the overall design of water quality detector.(2)Determining Raspberry Pi as the main controller of water quality detector,analyzing the theory and characteristics of temperature,turbidity,PH water quality sensor and LoRa communication module,and completing the hardware connection of water quality detector.(3)According to the hardware design of the water quality detector and the requirement of its operating environment,this paper analyses the functional requirements of the water quality detector.According to these functions,this paper builds the software development environment,and realizes the functions of information configuration,timing collection and data storage,data transmission and query of the water quality detector,and tests these functions.After testing,the water quality detector designed in this paper basically achieves the expected function and achieves the purpose of water quality detection.
