It is heartbreaking to acknowledge the fact that about one million of the babies born each day, die on the first day in the world. Shockingly, four million more of them die in the first month. These babies are vulnerable because of Preterm birth (birth at an early stage). About 25% of these deaths are related to neonatal babies with low birth weight (LBW), they are the ones in great danger. These babies are threatened because their bodies can’t withstand the inconsistent heat associated in the world outside the mother’s womb. A steady, warm temperature is required to keep their body fat and metabolic rate functioning properly. This paper tries to provide a solution to prevent the death of such babies. We have modeled, designed, and developed a neonatal incubator that has been embedded with a temperature and humidity control system. The chamber consists of two compartments; larger and smaller. The smaller compartment consists of a temperature and humidity control unit and the larger compartment consists of a space where the baby is kept. The smaller compartment or the control system components include relative sensors like a pulse sensor, fans, bulbs, heater, Arduino Nano microcontroller, etc. It functions with the help of the Arduino program which operates by controlling the temperature at the set level of 36°C and relative humidity at the set level of 65%. The microcontroller-based baby incubator helps people from all criteria; the cost of this project is very less than today’s baby incubator which is used in larger hospitals. So, everyone who belongs to the economic backward can also use it. This project does not only control the temperature and humidity inside the chamber but also provides several advantages such as displaying sensor data in the LCD as well as the website that has been built. The data are stored in a database which therefore can be further analyzed to discover new features about the baby. Thus, enhancing the scope of this project.
