Iot based smart cradle for crying baby
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryAs we are very well familiar with the hurdles faced by Parents to nurture their infant and especially in case if both the Parents are working. To give 24 hours of time in such cases is next to impossible. Thus, we need to develop something unique that can help Parents to have a continuous surveillance/watch on the Baby/Infant and can notify about the same.
Thus, we have come up with an idea to design a Smart Cradle System using IOT which will help the Parents to monitor their child even if they are away from home & detect every activity of the Baby from any distant corner of the world.
It is an innovative, smart & protective Cradle System to nurture an infant in an efficient way. This system considers all the minute details required for the care & protection of the Baby in the cradle.
Project Objectives- To design and fabricate a baby cradle with auto swinging support, web camera and musical toy.
- Reduce burden on women as a mother.
- Allow women to contribute more towards the society.
- Develop a system capable of soothing and monitoring the baby itself.
When the child is made to sleep on the cradle various sensors like noise sensor, DHT sensor, PIR sensor and camera module are implemented to monitor the various actions of the child.
• The equipment Baby care includes a dc motor, link, and an oscillating bed and sensors. The electric powered motor will actuate the links by shaft. Links actuates the rod attached to the bed at constant speed.
• The carriage is attached to the metal rod through springs which will provide a vibratory motion. It will also ensure the cradle motion even when the baby cries or moves using sensors. Motor, link and sensors are attached to the side of the cradle frame.
• When the motor rotates in clockwise direction it pushes the bassinet to front side & when motor rotates in anticlockwise direction it pushes the bassinet on the Either side. And in this way the system will keep working.
• Baby Cradle swings automatically when baby cries, for this it has a cry analyzing system which detects the baby cry voice and accordingly the cradle swings till the baby stops crying. • The speed of the cradle can be controlled as per the user need.
• The system has inbuilt alarm that indicates two conditions first when the mattress is wet, which is an important parameter to keep the baby in hygienic condition, second when baby does not stop crying with in a stipulated time, which intimated that baby needs attention
The working methodology of the proposed smart cradle system is as shown in Fig.
The above diagram depicts the complete working of the smart cradle system. When the child is made to sleep on the cradle various sensors like noise sensor, DHT sensor, PIR sensor and camera module are implemented to monitor the various actions of the child.
Benefits of the ProjectThe benefits of this cradle include:
a) It serves as a user friendly; it also reduces the manpower. The cradle can be adjusted in custom as per the user’s requirement and need.
b) User can set a particular time for cradle movement and while the user can complete their chores.
c) The most beneficial use of the product is, it uses neonatal and maternity units in hospital as bio-medical product. As this dwindles the labor of the nurses for taking care of infant and pamper them whenever they need.
Technical Details of Final DeliverableThe design of smartness & innovation comes with the use of technologies/methodologies which include Internet of Things (IOT) (Modules like Raspberry Pi, Arduino, Humidity & Temperature sensing), Swing Automation, Cry Detecting Mechanism, Live Video Surveillance, Cloud Computing (Data Storage) & User-Friendly Android Mobile Application (for User Controls).
