Over 62% of honey bee colony decline has been observed between June 2024 and February 2025. This study investigates bee stress level monitoring due to external disturbances like mechanical vibrations by measuring internal air temperature, relative humidity, and CO2 gas concentration levels of beehives. A new wireless sensor board for real-time monitoring of honey bee colonies was designed, built, and validated. The board incorporates NDIR-based SCD30 and SCD41 sensors for CO2, temperature, and humidity monitoring, integrated with a custom-designed two-layer printed circuit board and a Particle ArgonTM microprocessor for Wi-Fi communication. The developed board was tested and validated with live beehives in summer and winter of 2024 and 2025. The experimental study results showed the adequacy of the built sensor board. Bee colony responses on the applied stimuli (knocks) show that bees responded with a temperature increase of over 5 \u00b0C, CO2 concentration increase by 3000 to over 10,000 ppm, and, at the same time, relative humidity drop by about 10% inside beehives.<\/jats:p>","DOI":"10.3390\/s26061846","type":"journal-article","created":{"date-parts":[[2026,3,16]],"date-time":"2026-03-16T08:41:26Z","timestamp":1773650486000},"page":"1846","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["A Wireless Sensor Platform for Beehive Monitoring"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-2514-6180","authenticated-orcid":false,"given":"Sudipta Das","family":"Gupta","sequence":"first","affiliation":[{"name":"Department of Agricultural and Biosystems Engineering, North Dakota State University, Fargo, ND 58105, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey","family":"Erickson","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, North Dakota State University, Fargo, ND 58105, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph","family":"Rinehart","sequence":"additional","affiliation":[{"name":"USDA\u2014Agricultural Research Service, Fargo, ND 58102, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2575-7275","authenticated-orcid":false,"given":"Benjamin D.","family":"Braaten","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, North Dakota State University, Fargo, ND 58105, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7266-2201","authenticated-orcid":false,"given":"Sulaymon","family":"Eshkabilov","sequence":"additional","affiliation":[{"name":"Department of Agricultural and Biosystems Engineering, North Dakota State University, Fargo, ND 58105, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"180650","DOI":"10.1016\/j.scitotenv.2025.180650","article-title":"Insights from U.S. beekeeper triage surveys following unusually high honey bee colony losses 2024\u20132025","volume":"1003","author":"Nearman","year":"2025","journal-title":"Sci.
