Fecha de publicación: 28/08/2018 Fuente: Wipo "IOT" The utility model provides one kind based on NB is ioT's water quality monitoring node including microcontroller module, temperature acquisition module, conductivity module, pH value collection module, NB do ioT module and power constitute, NB it can be used to NB to contain in the ioT module the USIM card of ioT network. Does wherein the microcontroller module link to each other NB with temperature acquisition module, conductivity module and pH value collection module respectively the ioT module links to each other with the microcontroller module. A water quality monitoring system, NB the ioTwater quality monitoring node reads temperature, pH value, conductivity through microcontroller to do you pass through NB is the ioT module with data through NB ioT basic station, NB ioT core network, mobile communication NB the ioT platform finally reachs the water quality monitoring server. The water quality monitoring server with data storage to the database in, the quality of water data are looked over in real time to user's accessible PC end or cell -phone end. The utility model discloses is node integration degree height having NB communication distance is unrestricted under the ioT network condition, and it is good to have the commonality, and simple structure lays convenient advantage.
