A weather station built using 3D-printed parts and low-cost sensors, based on plans and guidance provided by the University Corporation for Atmospheric Research 3D-Printed Automatic Weather Station Initiative, was deployed alongside an Oklahoma Mesonet station to compare its performance against standard commercial sensors and determine the longevity and durability of the system. Temperature, relative humidity, atmospheric pressure, wind speed and direction, solar radiation, and precipitation measurements were collected over an 8-month field deployment in Norman, Oklahoma. Measurements were comparable to the commercial sensors except for wind direction, which proved to be problematic. Longevity and durability of the system varied, as some sensors and 3D-printed components failed during the deployment. Overall, results show that these low-cost sensors are comparable to the more expensive commercial counterparts and could serve as viable alternatives for researchers and educators with limited resources for short-term deployments. Long-term deployments are feasible with proper maintenance and regular replacement of sensors and 3D-printed components.

用更少的钱获得更多的科学:评估3D打印的气象站

根据大学大气研究公司3D打印自动气象站计划提供的计划和指导,使用3D打印零件和低成本传感器建造的气象站与俄克拉荷马州Mesonet站一起部署,以比较其性能与标准商业广告传感器并确定系统的寿命和耐用性。在俄克拉荷马州的诺曼进行了为期8个月的野外部署,收集了温度,相对湿度,大气压力,风速和风向,太阳辐射和降水量测量值。除了风向,测量结果与商用传感器相当,这被证明是有问题的。系统的寿命和耐用性各不相同,因为某些传感器和3D打印的组件在部署过程中发生了故障。总体,结果表明,这些低成本传感器可与价格更昂贵的商业传感器相媲美,并且可以作为资源有限的短期研究人员和研究人员的可行替代方案。长期部署是可行的,需要适当维护并定期更换传感器和3D打印组件。
