In modern scenario parents are so busy in their professional life, so it is quite difficult for them to take care of infants. So, there is need of some system which can help parents to monitor their child from remote location. This cradle is designed using android application which helps parents to monitor their child from their work place they can login anytime and see the activity of their child. In proposed system baby cradle is attached with a system which consist of dc motor which helps to swing the cradle, a cry detector which detects whether baby is crying or not, a wet sensor which detects the whether the mattress is wet or dry.
Nitin Bhatnagar designed Automatic & Indigenous E Cradle. when baby cries then E Cradle
swings automatically, to detects the baby crying voice microphone was used and the cradle swings
accordingly till the baby stops crying .wet sensor is used to detect the wetness . The system was
developed with an alarm that determines two conditions – first swing of cradle when baby doesn’t
stop crying within the time period of 2 minute. And second if the mattress is wet, that is the important
parameter to keep the baby in hygienic [
Adwait B Kadu gave an approach towards designing an automatically swinging cradle system. It
was integrated with a wet sensor and alarm if the baby found in wet condition which indicates that
baby needs immediate attention. DC motor was interfaced to obtain the rotational motion. As per
programming, the motor stated rotating in clockwise direction it pushes the baby bassinet as the free
wheel mounted on shaft is in contact with the semicircular strip under the bassinet and then for
particular time interval it rotated in anticlockwise direction [
Misha Goyal developed low cost indigenous electronic baby cradle. The speed of the cradle
controlled with baby cries, for that purpose to detect the cry sound ,microphone was used electric
signal was used to convert the cry into sound signal , in order to amplify the signals received through
MIC the signal conditioning circuit was used . To found both the conditions wet and cry the alarm
was implemented with the system [
Anritha Ebenezer Designed an automatic cradle swinging system for assisting infant care. It
consisted a cry detection system which analyzes the baby cry; whenever peak cry was detected ,the
signals was send to microcontroller then control signal send to the drivers and drivers derived the DC
motor accordingly. Which made the cradle to swing according to sound intensity varies. If still the
baby does not stop the crying within a particular instant of a time a call or message was be send to the
caretaker’s mobile number via GSM [
Steven Bang originated an automatic baby rocker with noise sensor implemented to detect baby
cry. That sensor which picks the sound signal from surrounding consists of electric MIC having
preamplifier circuit. Signal generated from noise sensor is fed to microcontroller which was used to
control the DC motor attached with rocker. Few colorful lights made up of LED were used to
entertain the baby being rocked [
Chau-Kai-Hsieh designed a baby cry analyzer that includes an amplifier circuit to amplify a sound
received. As a reply to the amplified sound signal, a pulse generator circuit with zero crossings. They
are aligned with the zero crossing of the amplified sound signal that is used to generate a pulse signal.
Then after pulse signal was given as the input to a signal recognition circuit. The output of signal
recognition was specifying that a baby’s cry is detected [
Gim Wong presented an electronic device that would be connected to traditional pivotally
mounted style crib. This was driven by baby cry voice picked up by the microphone giving short
throw type rocking action to crib [
Marie R. Harper Implemented a baby crib adapted to be swing automatically by an oscillatory
action of motor having the same function as would be achieved by a motor rocking a crib containing a
baby. When the crib was manually tilted in one direction and then released, this provided the inertia to
actuate the locking and initiate arms to operate under the biasing force of spring in synchrony with the
gear. Hence, the motor loaded with spring begin to operate and the lever which is attached to crib was
swinging in back and forth movement [
It acts as a processing unit for the system. This will pick the signals from the sensors and process them to take appropriate action. Microcontroller will be interrupted for immediate actions like in case of wet detected or baby cry. Microcontroller controls the motor with the help of driver circuit and provides smooth swing. 3.2
This will play an important role as far as baby comfort is concerned. It will send the signal in the form of current when the mattress is wet due to pee and inform the controller about the wet detection. In this sensor conducting tracks are designed with a small gap between two neighboring tracks. Conducting pee will short these tracks and the resistance of the sensor will reduce to nearly zero.
MIC
MIC is a sound sensor used to capture the baby cry in real time. When baby starts crying sensor will detect it and send signal to the microcontroller. Microcontroller convert this sound signal into electrical signal and after that this signal is passed to the amplifier.
The signal from MIC will be compared and conditioned to differentiate the baby cry from other noises. Also, this unit will be used to match all the frequency of signals with the system requirements. 3.5
This system consists of cry sensor, wet sensor and application for smart phone. The proposed system is attached to the cradle. When baby cries or wets mattress, sensor detect and send the signal to the microcontroller. Motor driver is attached to the controller after getting signal from controller it starts swinging the cradle. Simultaneously microcontroller also send signal to the server, and server enables webcam. After that webcam clicks the picture of baby. These pictures are uploaded on the server and stored in database. On the other hand, an android application is developed and installed on parent’s mobile phone. With the help of this android application parents can login and see the pictures of baby from anywhere anytime.
MIC is used to detect whether baby is crying or not and wet sensor is used to detect the wet condition. If baby cries or wet the mattress, cry sensor and wet sensor detects it send the signal to the microcontroller after processing signal microcontroller send the signal to the server.
In this system webcam is used. When cry or wet is detected microcontroller gives instruction to the server.
An android application is developed and installed on parent’s mobile phone. Parents can login and see the pictures of baby. By selecting date parents will be able to see the pictures of previous days also.
Thus, proposed system will be very helpful to the working parents as well as it will be also beneficial for the hospitals and creches. With the help of this system parents can get the information about the baby from remote location.
In future, many advancements can be performed. A voice recorder can be attached to the cradle in which mother’s voice can be record which can be played when baby cries. Many toys can also be attached to entertain baby.
