The night period, despite being a more restful period in which animals are theoretically sleeping and resting, represents approximately half of the life cycle of animals; therefore, its study is of immense interest. Wearable sensors have become a widely recognized technique for monitoring activity, both for their precision and the ease with which the sensorized data can be analyzed. The present dataset consists of data from the sensorization of 18 Serra da Estrela sheep, during the nocturnal period between 18 November 2021 and 16 February 2022. The data contain measurements taken by ultrasound and accelerometry of the height from neck to ground, as well as measurements taken by an accelerometer in the monitoring collar. Data were collected every 10 s when the animals were in the shelter. With the collection of data from various sensors, active and inactive periods can be identified throughout the night, quantifying the number and average time of those periods.<\/jats:p>","DOI":"10.3390\/data7090134","type":"journal-article","created":{"date-parts":[[2022,9,15]],"date-time":"2022-09-15T00:50:45Z","timestamp":1663203045000},"page":"134","source":"Crossref","is-referenced-by-count":5,"title":["Sheep Nocturnal Activity Dataset"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2322-3624","authenticated-orcid":false,"given":"Ant\u00f3nio","family":"Monteiro","sequence":"first","affiliation":[{"name":"Instituto Polit\u00e9cnico de Viseu, CERNAS\u2014Centro de Recursos Naturais, Ambiente e Sociedade, Escola Superior Agr\u00e1ria, Quinta da Alagoa-Estrada de Nelas, 3500-606 Viseu, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7696-4231","authenticated-orcid":false,"given":"Pedro","family":"Gon\u00e7alves","sequence":"additional","affiliation":[{"name":"Instituto de Telecomunica\u00e7\u00f5es and Escola Superior de Tecnologia e Gest\u00e3o de \u00c1gueda, Universidade de Aveiro, 3830-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5981-3829","authenticated-orcid":false,"given":"Maria R.","family":"Marques","sequence":"additional","affiliation":[{"name":"Instituto Nacional de Investiga\u00e7\u00e3o Agr\u00e1ria e Veterin\u00e1ria I.P.
