Child Guard: A Child Safety Monitoring System

Preterm delivery is defined as the occurrence of birth at less than 37 weeks of the gestation period. In 2015, the World Health Organization (WHO) estimated that in 1 million among 15 million of preemies do not survive due to prematurity, making in turn preterm birth ranked as the second-leading reason for death for children who did not complete their fifth year and the number one fatal syndrome in the first month after birth.

Infants who born before 37 weeks of the gestation period are known as preterm or premature babies. Study shows that in every month of birth around 4 million infants die in the world. 25% of the deaths are cause due to complications of prematurity, most often heat and water. Vital organs or enzymes of premature babies grow to the very lesser extent and thus requires special attention to cope with external physical condition like temperature, humidity, light etc. The infant has several disadvantages in terms of thermal regulation.

An infant has a relatively large surface area, poor thermal insulation, and a small amount of mass to act as a heat sink. The new-born has little ability to conserve heat by changing posture and no ability to adjust their own clothing in a response to thermal stress. So these parameters are most important to control for saving the lives of infants. In developing country because the economy is very low so the cost of medical devices should be kept low. Thus there is a need to develop a low cost incubator which provides the facilities required for the infants. This proposed system which includes system structure, hardware circuits and software program of the incubator for premature infant. In this project we use a temperature sensor, GSR (galvanic skin response) sensor. The goal of this project is to bring a new incubator which will be cost effective with improved usability.
