Therefore, residential institutions are eager to build an effective Internet of Things integration mechanism to assist institutions with automatic sensor detection and early warning capabilities. Although Internet of Things facilities have enabled prompt notification and warning of emergency events, the following problems exist when implementing Internet of Things in the facilities: (1) low compatibility between sensors has led to excessive installation costs; (2) warning systems that are based on fixed threshold values and lack of flexibility can cause false or omitted reports that result in the incapability of reflecting real conditions and additional labor costs would be required. This study uses a medical-grade Internet of Things module that can calculate the environmental values with edge computing to generate different levels of alarms by combining the index-weighted moving average method to dynamically calculate the optimal threshold value for the environment. It takes 2\u2009months to collect data from care institutions. The average F1-Score obtained in different environments is between 0.46 and 0.88. The results show that compared with using a fixed threshold, this method can effectively reduce sensor error notifications and missed notifications. <\/jats:p>","DOI":"10.1177\/15501477211059392","type":"journal-article","created":{"date-parts":[[2021,12,14]],"date-time":"2021-12-14T13:03:16Z","timestamp":1639486996000},"page":"155014772110593","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Using Internet of things technology to construct an integrated intelligent sensing environment for long-term care service"],"prefix":"10.1177","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6541-8641","authenticated-orcid":false,"given":"Lun-Ping","family":"Hung","sequence":"first","affiliation":[{"name":"Department of Information Management, National Taipei University of Nursing and Health Sciences, Taipei"}]},{"given":"Nan-Chen","family":"Hsieh","sequence":"additional","affiliation":[{"name":"Department of Information Management, National Taipei University of Nursing and Health Sciences, Taipei"}]},{"given":"Li-Ju","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Gerontological Health Care, National Taipei University of Nursing and Health Sciences, Taipei"}]},{"given":"Zong-Jie","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Information Management, National Taipei University of Nursing and Health Sciences, Taipei"}]}],"member":"179","published-online":{"date-parts":[[2021,12,14]]},"reference":[{"key":"bibr1-15501477211059392","first-page":"3","volume":"1","author":"Yin Y","year":"2016","journal-title":"J Ind Inform Integ"},{"first-page":"1","volume-title":"Proceedings of the 2011 2nd international conference on wireless communication, vehicular technology, information theory and aerospace & electronic systems technology (wireless VITAE)","author":"Rohokale VM","key":"bibr2-15501477211059392"},{"key":"bibr3-15501477211059392","doi-asserted-by":"publisher","DOI":"10.1109\/JSYST.2017.2662602"},{"key":"bibr4-15501477211059392","volume-title":"Introduction to statistical quality control","author":"Montgomery DC.","year":"2019","edition":"8"},{"key":"bibr5-15501477211059392","doi-asserted-by":"publisher","DOI":"10.1080\/00224065.1986.11979014"},{"key":"bibr6-15501477211059392","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2015.2437951"},{"key":"bibr7-15501477211059392","doi-asserted-by":"publisher","DOI":"10.1016\/j.iot.2019.100074"},{"key":"bibr8-15501477211059392","doi-asserted-by":"publisher","DOI":"10.1109\/TIM.2012.2218681"},{"first-page":"6","volume-title":"Proceedings of the 2006 1st international symposium on wireless pervasive computing","author":"Ohmura R","key":"bibr9-15501477211059392"},{"issue":"5","key":"bibr10-15501477211059392","first-page":"6","volume":"14","author":"Singh D","year":"2016","journal-title":"Int J Comput Sci Inform Sec"},{"key":"bibr11-15501477211059392","doi-asserted-by":"publisher","DOI":"10.1109\/JSYST.2014.2298837"},{"key":"bibr12-15501477211059392","doi-asserted-by":"publisher","DOI":"10.1016\/j.iot.2019.01.003"},{"key":"bibr13-15501477211059392","doi-asserted-by":"publisher","DOI":"10.1155\/2020\/8749764"},{"key":"bibr14-15501477211059392","doi-asserted-by":"publisher","DOI":"10.4018\/IJGHPC.2019100103"},{"first-page":"411","volume-title":"Proceedings of the 2015 IEEE recent advances in intelligent computational systems (RAICS)","author":"Kodali RK","key":"bibr15-15501477211059392"},{"key":"bibr16-15501477211059392","doi-asserted-by":"publisher","DOI":"10.1016\/j.apnr.2019.03.005"},{"first-page":"1","volume-title":"Proceedings of the 2018 wireless telecommunications symposium (WTS)","author":"Amiruddin A","key":"bibr17-15501477211059392"},{"key":"bibr18-15501477211059392","doi-asserted-by":"publisher","DOI":"10.1109\/TLA.2016.7786378"},{"key":"bibr19-15501477211059392","doi-asserted-by":"publisher","DOI":"10.1109\/COMST.2015.2444095"},{"first-page":"1","volume-title":"Proceedings of the 2015 2nd international symposium on future information and communication technologies for ubiquitous healthcare (Ubi-HealthTech)","author":"Shi Y","key":"bibr20-15501477211059392"},{"key":"bibr21-15501477211059392","doi-asserted-by":"publisher","DOI":"10.1109\/MPOT.2015.2456213"},{"first-page":"826","volume-title":"Proceedings of the 2015 12th annual IEEE consumer communications and networking conference (CCNC)","author":"Rahmani A","key":"bibr22-15501477211059392"},{"key":"bibr23-15501477211059392","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2017.10.011"},{"key":"bibr24-15501477211059392","doi-asserted-by":"publisher","DOI":"10.1109\/MNET.2017.1700030"},{"key":"bibr25-15501477211059392","doi-asserted-by":"publisher","DOI":"10.1016\/j.compeleceng.2018.02.047"},{"first-page":"356","volume-title":"Proceedings of the 2015 IEEE international conference on computer and information technology;
