In this study, we developed a smart mat with Internet of Things applied technology. The smart mat system composed of the hardware and software. The hardware contains multiple sensors connected to wireless network to transmit data from sensors to remote server. Also, the system can set the temperature at the optimal sleeping condition using a microcomputer. Furthermore, it can control the precision temperature controller at the unit of 1 grade and can control the controller at the minimum grade of 25–55. And the sensing data from smart mat are for remote monitoring of the elderly living alone or healthcare users, and a system model that can collect data on bedtime, wakeup time, and sleep quality. We developed an algorithm which could decides the status of sleep according to data from the sensors of the smart mat. There are nine types of status flags, which have the values from 1 to 9. This system can process the recorded contents and send the data to the smartphone application of the caregivers in real time for remote monitoring. Also, we developed the management system on the web to check the device status, permission, custom information, user information, and raw data.
