This baby monitor provides monitoring of a baby's activities and vital signs from a remote location, possibly anywhere in the world. A sensor unit placed near the baby receives input from the baby, typically sound, image and vital signs such as heartbeat, respiration and temperature. Environmental conditions such as ambient temperature can also be monitored. One embodiment of the invention is worn on, or close to, a baby's chest while sleeping and monitors heartbeats and generates an alarm if the heart rate drops unexpectedly, indicating distress such as lack of oxygen. The invention can also be used for parental reassurance by indicating the baby's heartbeat through a pulsating LED or audible sound.
