Controlling of Temperature and Humidity for an Infant Incubator Using Microcontroller

The preterm infant care is one of the most important ,delegate and sensitive area in the Bio-medical field. Preterm baby requires surrounding exactly similar as in the womb to cope with the external environment. To provide the similar environment as in the womb infants have to be kept in a device known as Incubator. An infant incubator provides stable levels of temperature, relative humidity. Air temperature has to be maintained around 35C The relative humidity should follow set values according to the incubation day number. The purpose of this project is to design and implement a closed loop control system to regulate the temperature and humidity inside a neonatal incubator. Also it is used to monitor and control the light and oxygen level in the incubator Microcontroller and PID controller will be used for implementing the hardware. The closed loop control system is a combination of sensors and actuators that operates synchronously to provide a stable thermal environment inside the incubator [3].
