Design of a home care instrument based on embedded system

An infant monitoring system based on the ARM embedded platform is proposed in this paper. Since both the parents need to work and look after their babies/infants simultaneously, these families bear more workload. Thus, this paper presents an innovative infant monitoring system consisting of an embedded system platform with a Linux kernel 2.4.18 embedded operation system using the TCP/IP protocol, a CMOS image sensor, and peripheral control systems. The key feature of the system is that it can be used to monitor the living environment and the activities of the babies and/or infants through a web browser at any time from any place in the world. In order to increase the accuracy of the temperature sensor, the measured values from the TMP75 digital temperature sensor were calibrated using regression analysis methods, resulting in an accuracy of plusmn 0.1degC, a correlation coefficient of 0.996, and a standard deviation of 0.124. The experimental results show that the proposed concept and the resulting system are feasible.
