Application of IoT sensor technology in water quality detection
The monitoring of the water environment generally has a relatively wide range of monitoring areas, including unpolluted water resources, polluted water resources, and so on. In the process of water quality monitoring, from judging and observing the quality of water quality to identifying and analyzing toxic substances in water quality, the Internet of Things technology makes the whole process of wireless module Factory water quality monitoring change by virtue of its accurate identification and rapid transmission of data information. It must be systematized and transparent, which is not only conducive to our grasp of the water quality status and its changing process, but also to better deal with problems such as abnormal effluent from environmental protection equipment and sewage treatment projects. With the development of society and people's attention to health issues in life, coupled with the deteriorating and shortage of water resources, the application of water quality monitoring systems has attracted the attention of the general public. With the gradual improvement and maturity of water quality monitoring technology , water quality monitoring technology has become the main means for environmental protection management departments to monitor the water quality and water conditions in the jurisdiction. The conventional laboratory sampling monitoring technology is completely backward, and it is impossible to obtain the pollution situation and accurate information of the water quality in the first time. Moreover, the analysis speed is slow, the operation is complicated, and the stability is poor. In addition, with the increasing pollution of water resources, the composition of water samples is becoming more and more complex, and more and more water quality items are tested, which has higher requirements for the performance of water quality analysis instruments. The water quality monitoring methods used in the past have been far from meeting the needs of the development of environmental protection work. Therefore, it is imperative to develop an online monitoring system for water quality. The water quality online monitoring system overcomes the shortcomings of conventional water quality analysis instruments, and the use of wireless data transmission equipment can provide ready and fast monitoring and transmission data in real time, continuously, stably and reliably. In my country, water environment monitoring mainly includes two aspects: water pollution monitoring and drinking water monitoring. Water pollution monitoring work is to detect wastewater, effectively prevent the occurrence of major wastewater pollution incidents, and reasonably control the discharge of wastewater; for drinking water monitoring work, sensors need to be installed in the water source area to be detected, every day. It is necessary to detect the water source indicators in the monitored area, and to understand the changes of the water source in real time, so as to provide people with safe and reliable drinking water. In the past, when environmental engineers conducted water quality testing, they generally adopted the method of on-site sampling and testing, that is, directly testing the outlet and inlet of sewage, and then analyzing the 4G/NB/GPRS/GPS/CAN wholesalers water quality to draw relevant conclusions. This traditional monitoring method was also used in the past rural sewage treatment projects, which consumed a lot of energy. And the results of monitoring and analysis have a certain degree of randomness. Therefore, it is difficult to reflect the actual pollution of the water environment. In the process of water pollution supervision and management, the difficulty coefficient is too large. The emergence of IoT sensor technology perfectly solves the above problems, not only enabling real-time monitoring, but also saving a lot of manpower and time during the monitoring process. PR |
