ABSTRACT
The customary Automatic child cradle frameworks
are excessively lavish and they additionally don't
offer much usefulness. Baby cuddle bed / cuddle nest
is a concept originated in Sweden. Baby cuddle bed
makes a cozy sleeping place for the baby and protects
baby at night because of stable bumper. We intends
to help those moms who are excessively occupied and
don't have a cleaning specialist or sitter to deal with
their infants. This paper portrays the configuration of
a programmed cradle which fundamentally chips
away at location of infant development with the
assistance of a PIR sensor. PIR sensor detects the
movement of infant. Another important feature is the
automated swing of the bed by means of voice
command which will work through an app. The
cuddle will also swing when the baby will start crying
inside the bed. The cradle additionally incorporates a
wet sensor which will caution the folks or the
Attendant/sitter for bunk wetting of the infant. It will
help to keep the infant in a hygienic environment. The
framework is kept negligible as far as fittings as
greatest measure of usefulness of the cradle is
performed through Arduino. The cradle is vitality
productive and obliges no physical consideration.
Keywords: Automatic cradle, bed-wet sensor,
PIR sensor, swinging of cradle, movement
detection.
1. INTRODUCTION
Generally, the baby cradle is used for to make sleep
and soothe to baby. For example guardian have to
take care of their child till as they asleep. However,
conventional cradle does not electronically equipped
such like battery or adapter to automate the cradle
automatically. In Addition to that, these kind of
conventional cradle is used in villages areas or non-
developed cities due to its low prices. But the
problem of this kind of designated cradle is that you
need manpower to take care of your child and your
child may not be safe and feel comfortable in the
conventional cradle. Thus, we need automatic cradle
to take care of child which uses the battery or power
source. Besides, there are extra features or function is
provided by the newly automatic cradle that is
beneficial for parents. Because in the present world
people are very busy in their professional life so they
do not get ample time to take care of their infants. It
will be very difficult control the babies and if
someone is hiring professional to take care of their
infants. It may increase your expenses from monthly
expenditure. Moreover, in today, life it is very hard to
even for the homemakers (mummy) to sit nearby
their babies and sooth them whenever they feel
uncomfortable. Though, it is automatic this
application is very useful for the nurses in maternity
units of hospital.
1.1 Objective of the project
1.1.1 To design the development of an intelligent
baby care, which has ability for automated swing,
bed-wet condition and body temperature?
1.1.2 To make a baby cradle is safe and comfortable
for baby with using PIR sensor to detect the
movement of the baby body as well as bed-wet
condition to keep away baby from hygienic
environment.
1.1.3 Automated swing of cuddle when baby is
crying.
1.1.4 To make cradle innovation that is more flexible
and less expensive to market.
1.1.5 User friendly- simple and complete with
instruction
1.2 Automated baby cradle bed
The requirement of automatic intelligent baby cradle
is day by day increasing. Especially in metropolitan
cities. The benefits of Automatic cradle are:
1.2.1 It is very easy to operate and it’s reduces the
manpower work. The user can adjust the cradle
according to their comfort and use.
1.2.2 User can adjust the time as per need of the
parent’s the how long cradle will move and the
parents can finish their household work in that
period.
1.2.3 The one of the most benefit of this cradle is we
can use cradle as a biomedical product in the
hospital. Hospital have neonatal and maternity units.
It will be helpful for the nurses to take care of infant
and sooth whenever they need. They do not have to
seat nearby.
2. METHODOLOGY
2.1 Hardware design and description
The following section describes the hardware that is
being used in the project.
A. Hardware Requirements
1. PIR sensor
2. Motor shield
3. Arduino UNO
4. Bluetooth module
5. Surface temperature sensor
6. Wet sensor
7. Power source
8. MOTOR
9. Activated relay KYO38 MICROPHONE SOUND
SENSOR/voice.
2.2 Procedure and purpose of material
(1) PIR Sensor- The PIR sensor has been used the
model HC-SR501 in this project to detect the baby
movement and procured from the local store[5].
(ii) Arduino UNO- Arduino UNO is the
microcontroller board and the Arduino AT MEGA
328 model has been used in this project and procured
from the local store. And arduino has been used for
the quickly developed interactive objects, taking
input from variety of switches or sensors and
controlling a variety of outputs such as automate the
motor and detect the temperature sounds and light
this is called physical computing[6].
(iii) Motor shield- The arduino motor shield has been
used and it is based on the H-bridge chip L 298 driver
integrated circuit .this motor shield mount with
arduino and enable the geared motor which help in
swing of cradle. This is procured from the local
store[8].
(v) As the name implies, a “gear motor” or “geared
motor” is a motor having an attached ”gear
assembly” (or gear train) which enables the gear
motor to provide greater torque at a lower rpm than
the motor alone would be capable of providing. In
our experiments however, we didn’t need the gear
assembly. We used a 300 rpm, 12V motor to control
the speed and direction and it is also procured from
the local market or store.
3. EXPERIMENTATION
3.1 Implementation of the PIR sensor
monitoring device
Pyro electric infrared (PIR) sensor is a strong state
sensor which is fit for catching infrared radiation
emanating from the objects[11]. The sensor
fundamentally measures the adjustments in the
infrared radiation amid development of the items, set
with in the field of perspective of the sensor. Since
the sensor is equipped for distinguishing articles
while they are in movement, they are regularly
viewed as movement finders. In this study, PIR
sensor was appended on the pole of the support in
order to identify the development of the child. Once,
the development of the infant is recognized, a control
sign was created to swing the support for the 5
minutes. In the event that the sensor recognized the
development of the infant after the progression of the
swing stage, the swing was rehashed for an additional
five minutes.
3.3 Implementation of the bed-wet sensing
system
A mesh like structure was produced on to a copper
clad board the cross section was comprised of two
leads with extended structures. The expanded
structures of the leads don't cover one another. In
other vicinity of Bed-wet condition, the leads was
associated with a 5V force supply through the
resistance of 55 kilo-ohm. The second lead was
joined with the ground. The yield of the framework
was taken from the 55kilo-ohm resistance and the
lattice lead. The yield was associated with the AIO
information of the Arduino UNO board. Under
typical circumstances the lattice surface will carry on
as open circuit and the yield of the sensor will be 5V.
On account of Bed-wet condition, there will a drop in
the yield voltage. A not as much as rationale was
connected to produce a control signal for the
actuation of the GSM module.
3.2 Implementation through mobile app
We will connect Arduino UNO board through a
Bluetooth module, the Bluetooth module will be
connected to the phone Bluetooth. And then after
connecting to the Bluetooth module, we will give the
voice command through an app from the phone,
which will control the swing of the cradle. The
diagram is shown in fig-1
3.4 Implementation through noise sensor
When the baby will start crying the noise sensor will
detect the sound and gives the signal to the Arduino
UNO for the implementation of the motor and thus
causing the swing of the bed.The diagram is shown in

4. RESULT ANALYSIS
We are successful in swing the cradle bed
automatically by using the motor and power
supply/battery. Now we are controlling the swing of
the bed by means of voice command by using
Arduino UNO, noise sensor, Bluetooth module and
motor controller.
5. CONCLUSION
In the present study, an intelligent baby cradle system
was developed. The cradle was capable of detecting
the movement of the baby and initiate cradle swing.
This project emphasis on providing ease for caring &
safety of the infants and reducing the pressure on the
parents.
