The proposed system integrates distributed sensor nodes built around the Heltec Mesh Node T114 platform, combining an nRF52840 microcontroller with an SX1262 LoRa transceiver to support low-power, long-range communication in agricultural environments. Environmental data acquisition is performed using integrated BME280 temperature, humidity, and pressure sensors, capacitive soil moisture sensors, and TEMT6000 light sensors. A custom firmware architecture extending the Meshtastic framework was developed to support sensor integration, telemetry generation, packet forwarding, and energy-aware scheduling within the LoRa mesh network. The platform combines embedded telemetry modules, intermediate routing mechanisms, and cloud-based microservices responsible for data aggregation and processing. Experimental results showed stable radio-link conditions in the tested node-to-router configuration, with RSSI values around −55 dBm and SNR values of approximately 6–7 dB. Channel utilization varied between approximately 4% and 12%, while transmission airtime utilization remained below 5%. These results support the feasibility of the proposed sensing, communication, and data-processing architecture under the tested configuration. The architecture is designed to accommodate additional sensing and routing nodes, while multi-hop performance, long-term energy consumption, and network scalability remain to be evaluated in larger deployments.","本文提出了一种基于嵌入式物联网传感、LoRa网状通信以及边缘—雾—云架构的低成本农业监测平台，专为智慧农业应用中的实时环境监测而设计。所提出的系统集成了围绕Heltec Mesh Node T114平台构建的分布式传感器节点，该平台将nRF52840微控制器与SX1262 LoRa收发器相结合，以支持农业环境中的低功耗、远距离通信。环境数据采集通过集成的BME280温度、湿度和气压传感器、电容式土壤水分传感器以及TEMT6000光照传感器完成。开发了一种扩展Meshtastic框架的定制固件架构，以支持LoRa网状网络内的传感器集成、遥测生成、数据包转发和能量感知调度。该平台结合了嵌入式遥测模块、中间路由机制以及负责数据聚合与处理的云端微服务。实验结果表明，在测试的节点到路由器配置中，无线电链路条件稳定，RSSI值约为−55 dBm，SNR值约为6–7 dB。信道利用率在约4%至12%之间变化，而传输空中时间利用率保持在5%以下。这些结果支持了所提出的传感、通信和数据处理架构在测试配置下的可行性。该架构设计可容纳额外的传感和路由节点，而多跳性能、长期能耗和网络可扩展性仍有待于在更大规模部署中评估。",null,"Sensors","2026-09-15T00:00:00Z","论文",10,false,71,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},12,20,17,13,9,1,"基于Meshtastic与LoRa组网的农业多传感器监测平台，含实测链路数据与云微服务架构，技术方案具体但尚属小规模验证，适合作为智慧农业物联网技术参考。",[25],{"name":10,"url":6},[27,28,29,30,31],"智慧农业","农业物联网","边缘计算","环境监测","LoRa",0,"10.3390\u002Fs26185839",{"doi":33,"openalex_id":35,"authors":36,"venue":10,"cited_by_count":32,"oa_url":6,"card":47,"direction":51,"ingested_from":53},"W7213352397",[37,39,42,45],{"name":38,"orcid":9},"Cătălin Negulescu",{"name":40,"orcid":41},"Theodor Borangiu","https:\u002F\u002Forcid.org\u002F0000-0002-4801-1951",{"name":43,"orcid":44},"Silviu Răileanu","https:\u002F\u002Forcid.org\u002F0000-0003-2301-4854",{"name":46,"orcid":9},"Victor-Valentin Anghel",{"tldr":48,"method":49,"finding":50,"direction":51,"opportunity":52},"提出基于Meshtastic LoRa网状网络与云微服务的低成本农业多传感器监测平台。","Heltec T114节点、BME280\u002F土壤湿度\u002F光照传感器、LoRa mes","测试链路RSSI约-55dBm、SNR 6-7dB，信道占用4%-12%，验证架构可行性。","智慧农业 \u002F 农业物联网","多跳性能、长期能耗与大规模网络扩展性尚未评估，可作后续研究切入点。","openalex","2026-09-16T23:30:12.438822Z"]
