Abstract: The purpose of this study is to present a novel real-time baby sleeping position monitoring and correction system to avoid Sudden Infant Death Syndrome (SIDS). The sensing module composed of 3-axis accelerometer is placed on the baby's forehead to monitor its position during sleeping by calculating the angles between gravity vector and its axis. System is driven by an inexpensive and low power microcontroller. The baby's sleeping position information is integrated to the correction system, which consists of a cradle and two servo motors. Cradle is designed to correct the sleeping position of the baby, and to avoid the SIDS.
