Wave‐generated flows, associated hydrodynamic forces, and disturbances created by them play critical roles in determining the structure and health of near‐shore coastal ecosystems. Oscillatory motions produced by waves increase delivery of nutrients and food to benthic organisms, and can enhance vertical mixing to facilitate delivery of larvae and spores to the seafloor. At the same time, wave disturbances can remove individuals and biomass with far‐reaching effects on critical coastal ecosystems and the biodiversity within them. Commercial instruments designed to measure wave characteristics and the effects of wave energy can be expensive to purchase and deploy, limiting their use in large quantities or in areas where they may be lost. We have developed an inexpensive open‐source pressure transducer data logger based on an Arduino microcontroller that can be used to characterize wave conditions for deployments lasting multiple months. Our design criteria centered around simplicity, longevity, low cost, and ease of use for researchers. Housed in ubiquitous polyvinylchloride (PVC) plumbing and constructed primarily with readily available materials, the Open Wave Height Logger (OWHL) can be fabricated in a college setting with basic shop tools. The OWHL performs comparably to commercial pressure‐based wave height data loggers during tests in the field, creating the opportunity to expand the use of these sensors for applications where sufficient spatial replication or risk of instrument loss would otherwise be cost prohibitive.

Open Wave Height Logger:用于压力测量的开源压力传感器数据记录器

波浪产生的水流,相关的水动力和由它们产生的扰动在确定近岸沿海生态系统的结构和健康方面起着至关重要的作用。波浪产生的振荡运动增加了向底栖生物的养分和食物的输送,并可以增强垂直混合,从而有利于将幼虫和孢子输送到海底。同时,波浪干扰可以清除对关键沿海生态系统及其内部生物多样性产生深远影响的个人和生物量。用于测量波浪特征和波浪能量影响的商业仪器购买和部署起来可能很昂贵,限制了它们的大量使用或可能会丢失的区域。我们基于Arduino微控制器开发了一种廉价的开源压力传感器数据记录器,可用于表征持续数月部署的波动情况。我们的设计标准围绕简单,寿命长,成本低以及研究人员易于使用等方面进行。Open Wave高度记录仪(OWHL)装在无处不在的聚氯乙烯(PVC)管道中,主要用容易获得的材料制成,可以在大学环境中使用基本的商店工具进行制造。在野外测试期间,OWHL的性能可与基于商业压力的波高数据记录器相媲美,这为将这些传感器的应用扩展到否则将无法实现足够的空间复制或仪器损失风险的应用创造了机会。
