• Abstract:

  Sudden infant death syndrome or better known as crib death, is the death that a baby usually suffers when they are asleep and have an interruption in air absorption because they do not yet have adequate control of their respiratory response. This project consisted of the design and construction of a control system that allows to detect when a baby in a crib is at risk of suffering the crib death. The designed control allows to control a mechanism with servo motors that will move to the crib so that the baby returns to a safe position. An important part of this project is the design of the PID Control Circuit that includes a Kalman Filter that will allow more effective control of the movement of the crib where the baby is sleeping. An accelerometer will detect the position of the baby in her crib and allow it to determine when the baby has been placed in a sleeping position that could cause crib death. When this happens, the corresponding control will be activated by means of servomotors placed at the base of the cradle to return it to a suitable position where there is no such danger. The device will also emit an audible alarm so that the parents or people close to the baby act accordingly. The microcontroller card used is the Raspberry Pi Pico. Tests were carried out on newborn babies to confirm the functionality of the designed device in terms of returning the baby to a suitable position for breathing when the baby's movement put this function at risk.
