Living with the sea, water management is of paramount importance to the Netherlands. Since the last century, the global average surface temperature has risen by 0.56°C-0.92°C, and the sea level has risen by about 0.17m. Climate change has caused frequent extreme weather events, which directly threatens the survival and development of the Netherlands in the lowland. The Dutch water department is constantly watching the rise in water levels. Because of the uncertainty, a small town suddenly disappeared someday. How to effectively and accurately monitor the groundwater level has become a problem for the Netherlands in the lowland. In response to this problem, the Dutch water company and SIMCom designed an intelligent groundwater meter. The groundwater meter is equipped with the SIMCom NB-IoT module SIM7020E, which has a wide coverage feature that enables the groundwater meter to have strong wireless communication capabilities, allowing signals to reach underground and monitoring points that are difficult to reach on radio and networks. The groundwater meter provides measurements every hour and sends the collected groundwater level information and related data to the cloud platform in real time via T-Mobile's NB-IoT network. The Dutch water company is therefore able to obtain real-time information remotely, effectively monitor groundwater levels, and calculate water demand.
In addition, the SIM7020E module supports PSM and eDRX low-power modes, and has low power consumption to minimize the power consumption of the ground meter, so the battery life is longer.xx
目前，荷兰自来水公司已在全国22个城市安装了这台NB-IoT地下水计。
说了这么多，小编忍不住介绍了这款智能手表的智能核心SIM7020E！ SIM7020E是一款多频段NB-IoT无线通信模块。它采用42 PIN LCC封装，具有丰富的硬件接口，如串行端口，GPIO和ADC。它使模块具有丰富的可扩展性，并为用户提供了出色的产品开发。方便。 SIM7020E的封装与SIM800C模块兼容，使客户可以轻松地从2G升级到NB-IoT。最大限度地缩短客户开发时间，加快客户产品的推出。作为低延迟，宽覆盖，低功耗，低吞吐量应用的最佳解决方案，SIM7020E模块非常适用于计量，远程控制，资产跟踪，远程监控，远程医疗和共享自行车等物联网应用。 *低功耗：该模块支持PSM和eDRX低功耗模式。理论上，两节5号电池可以支持10年。 *覆盖范围广：与GSM相比，NB-IoT具有强大的增益和广泛的信号覆盖范围，这使得该产品在地下室等地方具有强大的无线通信能力。关于Rihai Intelligent ---------------------------------------------- - - 日海智能科技有限公司（简称：日海智能，股票代码：002313），巨能集团控股公司，成立于2004年，成为人工智能物联网领域的领导者。 Rihai Smart为国内外运营商，ICT设备供应商，系统集成商和各行业用户提供业界领先的物联网云+端，云视频，数据中心，无线通信，有线宽带和新能源节能产品和解决方案。
