Although there are many sensors for sewage treatment, the iot water sensors are the most widely used. For users, the traditional submersible type or non-contact measurement cannot truly match with the technology of the Internet of things. However, in the iot era, not only life is inseparable from the Internet of things, but also industrial measurement is inseparable from the Internet of things sensors.

The real significance of iot water sensors for sewage treatment is that they can remotely monitor changes in sewage levels. Compared with manual submersible type and expensive non-contact water level measurement, their remote monitoring capability and the application of Internet technology are much more flexible. We only need to install the Internet of water level sensor in the wastewater or sewage treatment tank, pump sewage by setting the maximum level, so as to real-time monitor the change of water level, on the one hand, we can through the phone APP to observation data of sewage, once the maximum value of the sewage, the APP will be pushed to users via text message or messages in a timely manner to understand the latest trends of the sewage, the advantage is that the other two kinds of liquid level sensor is incomparable.

With the development of Internet of things technology, the iot water sensor is constantly being optimized, and the method of wireless communication is constantly being expanded. I believe that it will become more intelligent and scientific in the next few years.
