Recently, as interest in the environment has increased, various environmental pollution has emerged as a social problem, and among them, the water pollution problem has become a more serious problem because it leads to contamination of drinking water, which is essential for human survival.

That is, tap water was used as water to be consumed in most homes in the past, but recently, problems of water pollution have emerged, and as a result of increased disbelief in tap water, drinking water such as commercially available mineral water instead of tap water is used or water purifiers are used. The case is increasing.

However, even if a water purifier or bottled water is used instead of tap water, there is a limitation that the distrust of drinking water cannot be completely resolved because the water quality of purified water or commercially available drinking spring water cannot be directly checked by the general household or consumer. .

Therefore, in order to resolve the distrust of drinking water and to drink tap water with confidence, a water quality sensor is installed to accurately measure the water quality of the tap water flowing in the water supply pipeline and make it easy for ordinary users to know the measurement results. It is required to make sure that the tap water supplied to the home is in compliance with the standards for drinking water.

Therefore, in order to solve the problems of the water sensors of the prior art as described above, it can be easily installed at a low cost in the water supply pipeline or faucet of a general household to measure water quality information such as residual chlorine, electrical conductivity, and water temperature in tap water. It is configured to be able to check the measurement results in real time, and at the same time, in connection with information communication technology such as, for example, Narrow Band Internet of Things (NB-IoT), the quality of water in the water supply pipeline through the measured water quality information. It is desirable to provide a water supply sensor attached to a water supply pipeline based on the Internet of Things (NB-IoT) with a new configuration that is configured to monitor and provide waterworks information according to the user's needs, but still meets all such needs. No device or method has been provided.

Moreover, in order to solve the problems of the water sensors of the prior art as described above, the water quality sensor measured by the water sensor using an Internet of Things (NB-IoT) -based water supply pipe type water sensor configured as described above is used. Collecting water quality information to build big data on water quality and water use, and applying analysis methods such as deep learning to such big data to analyze information on water quality and water use, and various tap water information according to user's needs By being configured to provide a customized service, water service providers can monitor tap water for water quality vulnerable points, and for general consumers, it is easy to check water quality information about tap water, water purifier effluent, and village waterworks.
