PROJECT 2: BABY MONITORING SYSTEM USING

RASPBERRY PI

Introduction and Objectives

Parenting a small baby could be very hard when you have a large home and need to cook or

work in another room. Parents often find it very hard to check their baby continuously in the

cradle while they are in another room. Surely, you can’t leave the baby and focus on the work.

To resolve this problem we are going to build a baby monitoring system which can also be

described as a smart cradle system by using the power of IoT. This system could also be used

when the baby is under the supervision of a babysitter and parents are away as the system is able

to detect every activity. The parents are able to get every single minute detail that is required for

the care and protection needed for the protection of the baby in the cradle.

Methods

The Smart Cradle System will be using technologies and methodologies of IoT (Internet

of things). Our project will be utilizing smart modules like Raspberry Pi, Humidity&

temperature sensor, and camera sensor. The user will be able to use Cry Detecting

Mechanism, Live video Stream, Cloud Computing Storage, and a User-Friendly Web

Application (to control the system). To sense and detect the activities of the baby different

sensors could be attached to the cradle for accurate detection. For example temperature and

humidity sensing modules are used to detect the wetness of the bed, a camera mounted on

the top of the cradle to broadcast live footage of the baby to the parents. The data derived

from all the sensor of the system goes directly to the cloud (ThinkSpeak) and are analysed at

regular intervals. Lastly, a health algorithm is conducted to the datasets to receive informa-

tion about the body conditions of the baby. This greatly helps the parents to identify any

regular symptoms of a disease.

Nurturing a child when both the parents are working could the huge task filled with

hurdles. Thus, developing this system parents could have continuous surveillance over their

baby. In our method of building this project, both sensors and cloud technology will be used

to provide data with high accuracy about the activities of the child. The surveillance video

feed will be using a camera with Wide Area Network (WAN). This means the parents can

view the footage in the web application that can be accessed easily from any corner of the

world with an internet connection.

Hardware Requirements for the Project

• Raspberry Pi as the mainboard computer,

• Temperature sensor (LM 35),

• Humidity sensor,

• Sound sensor,

• MCP3008 (ADC IC),

• USB camera for the surveillance,

• SD card to store data, and

• Monitor.

Software Requirements for the Project

• Raspbian Jessie,

• HTML and PHP,

• MQTT protocol,

• Language-Linux, and

• Python.

What we will be Achieving?

Once we complete the Smart Cradle System, we will be able to analyse the activities of the child.

This will be completely enabled with Video Enhancement and Instant Web App notification

to provide superior monitoring of the baby. Plus, the system will have atomization with Real-

Time Database in the cloud. Lastly, the accurate sensors in the right placement will make baby

monitoring much easier and accurate for the parent.
