1. New low-cost options to long-term acoustic monitoring in terrestrial ecology are becoming increasingly available. However, integration of acoustic stations with sensors for logging of additional data, such as temperature and barometric pressure is rare. Separate environmental loggers often come at a cost of >US$100 whereas the same sensors for use with microprocessors come at a cost between US$ 1–15. The cost savings integration entails as well as the crucial need for the recording of some of these variables in acoustic studies mean that this is an important development avenue.
2. Overcoming these issues is important to enable insights into the long-term dynamics of ecological systems and how they respond to changes in the environment at varying temporal scales and is especially important for studies involving species that are heavily influenced by microclimate.
3. Here we present a hardware system for both acoustic and environmental data logging where the board design is released under a creative commons license. The system has been field tested in a tropical setting and is called the Kinabalu Recorder. The presented configuration came at a cost of <US$100 per station. This cost is for professional manufacture and assembly of the boards, temperature and barometric sensor, two batteries, waterproof housing and two 64 GB micro SD cards.
4. The system has been extensively tested in a tropical setting along an altitude gradient and with over 1.3 TB of data (>2,000 hr of data with over 10 months in the field) presents a robust solution to long-term acoustic monitoring integrated with environmental data sensors.
5. Work on hardware and software systems is an important part of the technological development of field biology as it allows greater flexibility in terms of cost and configuration of systems whilst promoting cross-field collaboration and information flow.

Kinabalu Recorder，一种新型无源声学和环境监测记录器

1. 陆地生态学中长期声学监测的新低成本选择正变得越来越可用。然而，将声学站与传感器集成以记录额外数据（例如温度和气压）的情况很少见。单独的环境记录器的成本通常超过 100 美元，而与微处理器一起使用的相同传感器的成本在 1-15 美元之间。成本节约集成需要以及在声学研究中记录其中一些变量的关键需求意味着这是一条重要的发展途径。
2. 克服这些问题对于深入了解生态系统的长期动态以及它们如何响应不同时间尺度的环境变化非常重要，对于涉及受小气候严重影响的物种的研究尤其重要。
3. 在这里，我们展示了一个用于声学和环境数据记录的硬件系统，其中电路板设计是在知识共享许可下发布的。该系统已经在热带环境中进行了现场测试，被称为 Kinabalu Recorder。所提供的配置成本低于每站 100 美元。这笔费用用于专业制造和组装电路板、温度和气压传感器、两块电池、防水外壳和两张 64 GB 微型 SD 卡。
4. 该系统已经在沿海拔梯度的热带环境中进行了广泛测试，数据超过 1.3 TB（超过 2,000 小时的现场数据，超过 10 个月的现场数据）为与环境数据传感器集成的长期声学监测提供了强大的解决方案.
5. 硬件和软件系统的工作是野外生物学技术发展的重要组成部分，因为它在成本和系统配置方面具有更大的灵活性，同时促进跨领域协作和信息流。
