Design and Development of Micro controller Based Temperature and Humidity Controller for Infant Incubator

Abstract

Infant incubator provides a controlled environment for newborns needing special care, such as those born prematurely. By placing an infant in an incubator, doctors and nurses can set and monitor different aspects of the child’s environment in order to create ideal conditions for survival and moreover it protect infants from pollutants and infection. Infant incubators and other advances in medical technology have made it possible for small or premature babies to survive in higher numbers than they did in the middle of the 20th century. Design and development of microcontroller based temperature and humidity controller for an infant incubator monitors and controls these two parameters constantly which are very critical for the normal growth of the new born (premature) babies In this thesis work, focus has been to develop: 1. Hardware for temperature and humidity control 2. Compatible software This system can automatically control the infant’s temperature at optimum level using PID concept and to maintain high relative humidity so as to minimize the thermal loss. The developed system must be user friendly, cost effective and accurate.
