Child safety seats with alarms notify the driver of a vehicle that an infant is in its carrier inside of the vehicle when a door is opened. Forgetting a child inside of the vehicle can result in severe injury to or the death of the child from extreme temperature conditions and/or dehydration. Child safety seats with alarms not only protect the child in the event of accident, but also detect the opening of a vehicle door and remind the driver of the presence of the child through visual and audio alerts. The detector and alarm system are automatically engaged when the buckle of the child safety seat is closed. The condition of the batteries powering the detector and alarm system are also monitored so that the user can be confident that the detector and alarm system have adequate power to function. A pressure transducer is employed as a detector to sense the changing air pressure caused by the opening or closure of a vehicle door. When such a condition is detected, red LEDs light up and an alarm is sounded from a speaker.
