A baby monitoring system for remotely monitoring a child's breath rate and body orientation is disclosed. The system comprises, in one embodiment, a parent unit retained by a supervisor, a sensor unit removably engaged around the child's abdomen, and a nursery unit positioned proximal the child, preferably in the same room. The sensor unit provides at least two tri-axial accelerometers positioned and configured such that each is independently capable of measuring both the child's breath rate and body orientation, even where the child's body is oriented such that movement of at least one of the accelerometers is restricted. The sensor unit then wirelessly transmits this information to the nursery unit, which performs necessary calculations and transmits this data to the parent unit, which displays the data on a display screen. Additionally, the system is capable of recording and reproducing a heart beat sound of the child's mother. |
