群居昆虫的许多集体行为都是由气流调节的，例如蜜蜂在嗅觉搜索和聚集过程中扇动翅膀来驱动巢的通风或驱散信息素。对个别昆虫的局部感应和驱动如何放大以产生如此大规模的流动的经验研究需要分布式流动测量技术。然而，普通的基于视觉的技术在这些群居昆虫生活和行为的混乱动态环境中是不可行的。在这里，我们开发了一种可定制的、低成本的2D流量传感器，它可以测量大小和方向，并可以部署在实验表面的密集传感器阵列中。虽然已经发表了许多2D热流量传感器设计，但我们的最小设计使用了现成的组件和标准制造技术，大多数研究小组都应该可以使用这些技术。在这里，我们报告了我们的传感器的设计和性能，并提供了用户友好的校准协议。该传感器的测量范围为0-2m/S，精度为0.1m/S，角分辨率为3，时间常数为3 S。
Many collective behaviors in social insects are mediated by airflow, such as honeybees fanning their wings to drive nest ventilation or to disperse pheromones during olfactory search and aggregation. Empirical investigations of how the local sensing and actuation of individual insects scale up to produce such large scale flows require distributed flow measurement techniques. Common vision-based techniques, however, are not workable in the cluttered dynamic environments in which these social insects live and behave. Here, we developed a customizable, low-cost 2D flow sensor that can measure both magnitude and direction and be deployed in dense sensor arrays on experimental surfaces. While many 2D thermal flow sensor designs have been published, our minimal design uses off-the-shelf components and standard fabrication techniques that should be accessible to most research groups. Here we report on the design and performance of our sensor and provide a user-friendly calibration protocol. The sensor has a measurement range of 0–2 m/s with accuracy of 0.1 m/s, angular resolution of, and a time constant of 3 s. We also discuss modifications that can be made to tune sensor performance for a given application.
