Air, water, and soil are essential for terrestrial life, but pollution, overexploitation, and climate change jeopardize the availability of these primary resources. Thus, assuring human health and food production requires efficient strategies and technologies for environmental protection. Knowing key parameters such as soil moisture, air, and water quality is essential for smart farming and urban development. The MeteoMex project aims to build simple hardware kits and their integration into current Internet-of-Things (IoT) platforms. This paper shows the use of low-end Wemos D1 mini boards to connect environmental sensors to the open-source platform ThingsBoard. Two printed circuit boards (PCB) were designed for mounting components. Analog, digital and I2C sensors are supported. The Wemos ESP8266 microchip provides WiFi capability and can be programed with the Arduino IDE. Application examples for the MeteoMex aeria and terra kits demonstrate their functionality for air quality, soil, and climate monitoring. Further, a prototype for monitoring wastewater treatment is shown, which exemplifies the capabilities of the Wemos board for signal processing. The data are stored in a PostgreSQL database, which enables data mining. The MeteoMex IoT system is highly scalable and of low cost, which makes it suitable for deployment in agriculture 4.0, industries, and public areas.

MeteoMex：用于网络环境监测和农业4.0的开放基础架构

空气，水和土壤对于地球生命至关重要，但是污染，过度开发和气候变化危害了这些主要资源的可利用性。因此，确保人类健康和粮食生产需要有效的环境保护战略和技术。了解关键参数（例如土壤湿度，空气和水质）对于智能农业和城市发展至关重要。MeteoMex项目旨在构建简单的硬件套件并将其集成到当前的物联网（IoT）平台中。本文展示了如何使用低端Wemos D1微型板将环境传感器连接到开源平台ThingsBoard。设计了两个印刷电路板（PCB）用于安装组件。支持模拟，数字和I2C传感器。Wemos ESP8266芯片具有WiFi功能，可以使用Arduino IDE进行编程。MeteoMex Aeria和terra套件的应用示例展示了它们在空气质量，土壤和气候监测中的功能。此外，显示了用于监视废水处理的原型，该原型说明了Wemos板进行信号处理的功能。数据存储在PostgreSQL数据库中，该数据库可以进行数据挖掘。MeteoMex物联网系统具有高度的可扩展性和低成本，使其适合在农业4.0，工业和公共区域中部署。可从https://github.com/robert-winkler/MeteoMex免费下载电路图，PCB布局和代码示例。和气候监测。此外，显示了用于监视废水处理的原型，该原型说明了Wemos板进行信号处理的功能。数据存储在PostgreSQL数据库中，该数据库可以进行数据挖掘。MeteoMex物联网系统具有高度的可扩展性和低成本，使其适合在农业4.0，工业和公共区域中部署。可从https://github.com/robert-winkler/MeteoMex免费下载电路图，PCB布局和代码示例。和气候监测。此外，显示了用于监视废水处理的原型，该原型说明了Wemos板进行信号处理的功能。数据存储在PostgreSQL数据库中，该数据库可以进行数据挖掘。MeteoMex物联网系统具有高度的可扩展性和低成本，使其适合在农业4.0，工业和公共区域中部署。可从https://github.com/robert-winkler/MeteoMex免费下载电路图，PCB布局和代码示例。这使其适合在农业4.0，工业和公共区域中部署。可以从https://github.com/robert-winkler/MeteoMex免费下载电路图，PCB布局和代码示例。这使其适合在农业4.0，工业和公共区域中部署。可从https://github.com/robert-winkler/MeteoMex免费下载电路图，PCB布局和代码示例。
