Amidst the challenges of global population growth and the need for sustainable, high-yield agricultural practices, PA, supported by modern technology and data-driven methodologies, emerges as a pivotal approach for optimizing crop yield and resource management. The proposed monitoring system integrates Wireless sensor networks (WSNs) into PA, enabling real-time acquisition of environmental data and multimodal observations through cameras and microphones, with data transmission via LTE and\/or LoRaWAN for cloud-based analysis. Its main contribution is a physically modular, pole-mounted station architecture that simplifies sensor integration and reconfiguration across use cases, while remaining solar-powered for long-term off-grid operation. The system was evaluated in two field deployments, including a year-long wild-flora monitoring campaign (three stations; 365 days; 1870 images; 63\u2013100% image-based operational availability), during which stations remained operational through a wildfire event. In the viticulture deployment, the acoustic module supported bat monitoring as a bio-indicator of ecosystem health, achieving bat call detection performance of 0.94 (AP Det) and species classification performance of 0.85 (mAP Class). Overall, the results support the use of modular, energy-aware monitoring stations to perform sustained agricultural and ecological data collection under practical field constraints.<\/jats:p>","DOI":"10.3390\/agriculture16010069","type":"journal-article","created":{"date-parts":[[2025,12,29]],"date-time":"2025-12-29T07:52:59Z","timestamp":1766994779000},"page":"69","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Interoperable IoT\/WSN Sensing Station with Edge AI-Enabled Multi-Sensor Integration for Precision Agriculture"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-5932-5718","authenticated-orcid":false,"given":"Matilde","family":"Sousa","sequence":"first","affiliation":[{"name":"C-MAST\u2014Centre for Mechanical and Aerospace Science and Technologies, 6201-001 Covilh\u00e3, Portugal"},{"name":"Department of Electromechanical Engineering, University of Beira Interior, Cal\u00e7ada Fonte do Lameiro, 6200-358 Covilh\u00e3, Portugal"}]},{"given":"Ana","family":"Alves","sequence":"additional","affiliation":[{"name":"C-MAST\u2014Centre for Mechanical and Aerospace Science and Technologies, 6201-001 Covilh\u00e3, Portugal"},{"name":"Department of Electromechanical Engineering, University of Beira Interior, Cal\u00e7ada Fonte do Lameiro, 6200-358 Covilh\u00e3, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-6599-6905","authenticated-orcid":false,"given":"Rodrigo","family":"Antunes","sequence":"additional","affiliation":[{"name":"C-MAST\u2014Centre for Mechanical and Aerospace Science and Technologies, 6201-001 Covilh\u00e3, Portugal"},{"name":"Department of Electromechanical Engineering, University of Beira Interior, Cal\u00e7ada Fonte do Lameiro, 6200-358 Covilh\u00e3, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0672-0378","authenticated-orcid":false,"given":"Martim","family":"Aguiar","sequence":"additional","affiliation":[{"name":"C-MAST\u2014Centre for Mechanical and Aerospace Science and Technologies, 6201-001 Covilh\u00e3, Portugal"},{"name":"Department of Electromechanical Engineering, University of Beira Interior, Cal\u00e7ada Fonte do Lameiro, 6200-358 Covilh\u00e3, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1691-1709","authenticated-orcid":false,"given":"Pedro Dinis","family":"Gaspar","sequence":"additional","affiliation":[{"name":"C-MAST\u2014Centre for Mechanical and Aerospace Science and Technologies, 6201-001 Covilh\u00e3, Portugal"},{"name":"Department of Electromechanical Engineering, University of Beira Interior, Cal\u00e7ada Fonte do Lameiro, 6200-358 Covilh\u00e3, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7177-751X","authenticated-orcid":false,"given":"Nuno","family":"Pereira","sequence":"additional","affiliation":[{"name":"C-MAST\u2014Centre for Mechanical and Aerospace Science and Technologies, 6201-001 Covilh\u00e3, Portugal"},{"name":"Department of Electromechanical Engineering, University of Beira Interior, Cal\u00e7ada Fonte do Lameiro, 6200-358 Covilh\u00e3, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4890","DOI":"10.1109\/JIOT.2018.2879579","article-title":"Internet of Things (IoT) for smart precision agriculture and farming in rural areas","volume":"5","author":"Ahmed","year":"2018","journal-title":"IEEE Internet Things J."},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Popescu, D., Stoican, F., Stamatescu, G., Ichim, L., and Dragana, C.
