开发了低成本的“物联网”（IoT）验潮网络，以提供实时和“延迟模式”海平面数据，以支持对沿海空间和时间形态变化的监测。它基于Arduino Sigfox MKR 1200微控制器平台，带有Measurement Specialties压力传感器（MS5837）。在两个与已建立的验潮仪共址的地点进行的实验表明，这些廉价的压力传感器可以进行精确的海平面测量。虽然这些压力传感器能够达到类似于1厘米的精度，但与其他类似的仪表一样，显著的波浪活动的影响可能会扭曲整体海平面测量结果。对各种现成的硬件和软件配置进行了测试，以提供补充数据，作为局部网络的一部分，并克服业务上的制约因素，例如缺乏安装验潮仪的适当基础设施和暴露的海滩地点。
A low-cost "Internet of Things" (IoT) tide gauge network was developed to provide real-time and "delayed mode" sea-level data to support monitoring of spatial and temporal coastal morphological changes. It is based on the Arduino Sigfox MKR 1200 micro-controller platform with a Measurement Specialties pressure sensor (MS5837). Experiments at two sites colocated with established tide gauges show that these inexpensive pressure sensors can make accurate sea-level measurements. While these pressure sensors are capable of similar to 1 cm accuracy, as with other comparable gauges, the effect of significant wave activity can distort the overall sea-level measurements. Various off-the-shelf hardware and software configurations were tested to provide complementary data as part of a localized network and to overcome operational constraints, such as lack of suitable infrastructure for mounting the tide gauges and for exposed beach locations.
