For a successful implementation, these strategies require continuous feedback of the soil and crop water status. This feedback is provided by physical indicators from the soil\u2013plant\u2013atmosphere continuum, as is the case of the crop canopy temperature, which can be used for the indirect estimation of crop water stress. Infrared Radiometers (IRs) are considered as the reference tool for temperature-based water status monitoring in crops. Alternatively, in this paper, we assess the performance of a low-cost thermal sensor based on thermographic imaging technology for the same purpose. The thermal sensor was tested in field conditions by performing continuous measurements on pomegranate trees (Punica granatum L. \u2018Wonderful\u2019) and was compared with a commercial IR. A strong correlation (R2 = 0.976) between the two sensors was obtained, demonstrating the suitability of the experimental thermal sensor to monitor the crop canopy temperature for irrigation management.<\/jats:p>","DOI":"10.3390\/s23062915","type":"journal-article","created":{"date-parts":[[2023,3,8]],"date-time":"2023-03-08T02:08:14Z","timestamp":1678241294000},"page":"2915","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Automatic Crop Canopy Temperature Measurement Using a Low-Cost Image-Based Thermal Sensor: Application in a Pomegranate Orchard under a Permanent Shade Net House"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7170-5137","authenticated-orcid":false,"given":"Jaime","family":"Gim\u00e9nez-Gallego","sequence":"first","affiliation":[{"name":"Department of Automation Engineering, Electrical Engineering and Electronic Technology, Technical University of Cartagena, Campus Muralla del Mar s\/n, E-30202 Cartagena, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6746-2961","authenticated-orcid":false,"given":"Juan D.","family":"Gonz\u00e1lez-Teruel","sequence":"additional","affiliation":[{"name":"Department of Automation Engineering, Electrical Engineering and Electronic Technology, Technical University of Cartagena, Campus Muralla del Mar s\/n, E-30202 Cartagena, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1492-8347","authenticated-orcid":false,"given":"Pedro J.","family":"Blaya-Ros","sequence":"additional","affiliation":[{"name":"Department of Agronomic Engineering, Technical University of Cartagena, Campus Paseo Alfonso XIII 48, E-30203 Cartagena, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6375-0456","authenticated-orcid":false,"given":"Ana B.","family":"Toledo-Moreo","sequence":"additional","affiliation":[{"name":"Department of Automation Engineering, Electrical Engineering and Electronic Technology, Technical University of Cartagena, Campus Muralla del Mar s\/n, E-30202 Cartagena, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6432-2322","authenticated-orcid":false,"given":"Rafael","family":"Domingo-Miguel","sequence":"additional","affiliation":[{"name":"Department of Agronomic Engineering, Technical University of Cartagena, Campus Paseo Alfonso XIII 48, E-30203 Cartagena, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8205-8518","authenticated-orcid":false,"given":"Roque","family":"Torres-S\u00e1nchez","sequence":"additional","affiliation":[{"name":"Department of Automation Engineering, Electrical Engineering and Electronic Technology, Technical University of Cartagena, Campus Muralla del Mar s\/n, E-30202 Cartagena, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Kannan, N., and Anandhi, A.
