Abstract

In today’s world we see that most of the families consist of mainly the

parents and children. When a baby is born in a family there has to be

someone to look after the baby. Some parents have to do a double task of

keeping a check on the baby as well as do the household work. Keeping a

nanny could be an option but not all can afford nannies and also it is always

difficult for parents to rely on some strangers to look after their baby. So to

help such parents we have decided to come up with a smart cradle gear

which will help a mother or a father have a track of their child and do some

household work simultaneously. The idea is to design a smart cradle

alarming system that will signal the parents of the baby’s activities. The gear will be such that it will fit most of the common cradles or cribs. The

system will comprise of sensors, which will detect the baby’s activities and alarm their parents.

I. INTRODUCTION

In today’s world, the safety of the baby is of utmost importance, so to help such parents out we have decided to come up with a smart cradle gear, which will help a mother or father to

have a track of their child and do some household work simultaneously. The idea is to design

a smart cradle alarming system that will signal the parents of the baby’s activities. The gear will be such that it will fit most of the common cradles or cribs. The system will comprise of

sensors that will detect baby’s activities and alarm their parents.

IoT has truly change the way of everyday living of the people ensuring safety, security, new

technological innovations where several devices are connected over the network and data is

exchanged from device to device. IoT has various applications over various fields such as

healthcare, automotive, monitoring devices, home automation, security devices using

alarming systems etc. Combining IoT with cloud and distributed computing, data science has

contributed greatly towards the new smart innovations.

II. BACKGROUND TO THE STUDY

Chau-Kai-Hsieh developed a system which includes an amplifier circuit for amplifying a

sound signal that is received. For this sound signal generated as output ,a pulse signal

having zero crossings which is generated by a pulse generator which are aligned with zero

crossings of the amplified sound signal. The pulse signal is the input to a signal

recognition circuit. An output signal is generated by signal recognition circuit indicating

whether a baby was crying or not.

Amritha Ebenezer proposed to design a baby cradle equipped with cry analyzing system

that detects baby cry. According to the intensity of sound the cradle swings. It has wet

sensor to indicate the wetting of baby. Whenever the baby wets, resistance would change

thus sending a signal. Other sensors include temperature sensor to display baby

temperature. GSM modem via RS232 has been used to send message to parents in case

baby does not stop crying with in a particular instant of time.

III. OVERVIEW & PLANNING

3.1 Proposed System Architecture Overview

The overview of the gear consists of an Arduino board to which all the three sensors are

connected. These serve as the inputs to the Arduino as they feed the Arduino with analog

data which it manipulates according to the sketch provided to the Arduino. Bluetooth

Module has been used for transmitting the data to mobile device. According to the data,

parents can take the action they want to, depending upon the situation.

Whenever the baby will cry in the cradle, the noise will detected by the electret microphone

and will be amplified, the changes in the readings are then used as input for manipulating

the code and the readings are sent to the mobile app.The 5V battery powers the Arduino and

all the sensors will be properly soldered so there is no error in the readings.

3.1.2 Architecture Specification

The architecture consists of Arduino board and 3 sensors namely Water Sensor YL-83,

Electret Microphone and CZL601 Load Cell (40kg) with HX711.

The serial transfer of data from serial monitor is communicated by Bluetooth module

to an android application.

Here are the pin diagrams for the following components :-

V. ALGORITHM DESCRIPTION

Nowadays most of the parents are working parents or single parents who are working and

have a busy schedule throughout the day so there is heavy dependency on the security

electronic devices to monitor the safety of the baby, which is of the utmost importance. The

dependence on the technology has also increased due to the increase in number of criminal

cases reported when the baby is alone with the guardian or nanny. Here we propose an

application of IoT (Internet of Things) based on the sensor devices that record the real-time

reading and send it to mobile and if necessary create an alert so that immediate action is

taken and baby can be rescued accordingly. The most important aspect of this algorithm is

that the data recorded must be accurate so that there are no false alarms. To ensure this, we

did excessive testing to make the gear error free.

The gear comprises of three sensors namely the water sensor, load cell and electret

microphone; all connected to Arduino board through analog and digital pins. Load cell

comes with an amplifier module attached to it, which amplifies the signals of load cell. The

load cell measures the stress value and the change in stress value can be manipulated

according to our need. The water sensor has thin lines on its surface which gets connected as

the water droplet falls on it. Electret Microphone detects the signals in form of sound and

converts it to electrical signals, which needs to be modulated using an amplifying circuit.

Clapping circuit is used as an amplifying circuit .Buzzer can also be added as an alarming

mechanism. On receiving the data from the sensors during the testing phase ,readings were

noted and code can be manipulated accordingly to get the desired update on the mobile app

which can be seen in the screenshots(Figure. 8 & Figure 9) Electret microphone will also

give the readings of the noise disturbances so to avoid the errors , we could set a certain

threshold according to the pitch and the noise of the baby , only if that threshold is crossed,

the sensor will give the reading as “Baby is crying”.In the last phase of the algorithm, all the data is sent to mobile app triggers an alarming system that would immediately rescue the

baby.The flowchart of our algorithm is as shown in Figure. 6. It depicts the exact algorithm

as explained here used to detect fallacy and sharp changes,. It shows the step by step how

the devices work and on what condition the message will be sent to mobile device.

VI. RESULT

Here the baby was put into the cradle and the readings were taken by sensors. Initially the

baby started crying so it was sent to the app that baby is crying. When the baby was picked

up from the cradle and simultaneously little water was put on the bed-sheet of the cradle, it

showed the result as baby is wet and baby is out of cradle in serial monitor and the same

reading is being sent to mobile application in real-time. Figure. 6 & Figure. 7 show the

screenshots of serial monitor and mobile application.

VII. ADVANTAGES

1. The gear is cheap and easy to install in any cradle, stroller, or small bed of the baby.

This is entirely dependent on user’s choice. 2. Usage of three sensors make sure that the baby is overall secured unlike other smart

cradle which focuses on one of the functionality not ensuring full security.

3. Apart from having a Buzzer and alarm system, the gear is also connected to mobile

device which is an excellent application of IoT that will help in increasing the

connectivity of parents with their baby, so that they can peacefully carry on with their

work even from far places.

VIII. CONCLUSION & FUTURE SCOPE

The above proposed IoT based algorithm is designed to connect the parents to the baby

through a device in order to keep the parents informed about the security of baby when they

are not close to their baby. The sensors used ensure that the major aspects of security are

covered. Parents can keep a check on their baby very easily through a mobile device. The

algorithm fits best for the working parents or those who travel a lot especially for business

purpose. There is also large amount of opportunity that opens up in order to modify the

system further to extend the level of security using other different sensors, using cloud

computing technique and machine learning to extend the further research. The IoT has

transformed our everyday lives at a significant exponential rate. The idea of connecting the

information recorded from surroundings using complex sensors and sending it to mobile

device shows the vast possibilities of how IoT can influence the lives of people through

smart devices - what they are called these days. We have already seen the reach of IOT in

medical, security, environmental and many other fields. For example – The Running hand or

wrist gear that measures all the vital statistics of the body and sends it to your device in real-

time and you can easily monitor your performance.

To enhance the security of the baby apart from the basic requirement more modules can

be added like PIR sensor to detect the motion, camera to see the surroundings or the

person who has been around the baby.

To extend the range of the signals we can implement the same circuit with help of GSM

module and Wifi module. Using GSM module, the message can be send to parent even in

different city, country so parents can monitor their baby even on business trips for

companies.

One of the most important feature that can be added to this device is that a trigger can be

added in such a way that if the parents are very far away in different city or they could

not reach to their baby than through the app they should be able to trigger an emergency

help with nearest police station. For this GPS services can also be included. This ensures

expert level safety for the child.

More sensors to record statistics of body like body temperature, heartbeats, sleeping

pattern can be observed and using data science technology more information about the

baby can be known.

The data received from the sensors can be stored in the database and using data analytics

a pattern can be recorded when the baby cries or at what time of the day the baby wets

the bed the most. This would increase the credibility of the gear using the machine

learning techniques, prediction & modeling.

The mobile app we used for the prototype model is the built-in app for Bluetooth module.

Depending upon the requirement, android or ios app can be made which increases the

scope of project in app development framework. Additional functionalities like triggering

emergency from app, tracking the baby from app using GPS can also be added.

This cradle gear opens up the enormous opportunities in fields of cloud computing, data

science, algorithms, security, statistics & databases. As a result, we conclude our algorithm

by developing a prototype gear, which can be fitted into any baby cradle to ensure the safety

of the baby. The sensors used in the project will send the data to the serial port which is send

to the android app of the android phone of the parents and they get alerted that their baby

might be in danger and need some urgent help. We have also included a buzzer that can alert

the parents at home directly.
