IoT Based Smart Cradle System

IoT or the internet of things is characterized as a forthcoming innovation that empowers us to create worldwide networked machines and also the devices that can be helped for exchanging of communication. As we all know that the real-time application has been increasing day by day, the smart connection also had increased. Rapid population growth, led to the increase in global life expectancy and the advance of technology, paving the pathway for the creation of age-friendly environments. This had led to the necessity in designing new products for Infants protection. 

Infants or toddlers need parents’ attention 24×7. In this present era, the number of working mothers has greatly increased. As a result, baby care has become a daily challenge for many families. Thus, most parents send their babies to their grandparents’ houses or to baby care houses. However, the parents cannot continuously monitor their babies’ conditions either in normal or abnormal situations. Still, certain incidents like infant attacks have been reported, it is necessary to protect the baby.

Our proposed system is based on the Internet of Things-based Smart Infant Cradle System designed as an efficient and low-cost IoT-based system for monitoring infants in real-time. This system plays a key role in providing better baby care while parents are away.

“Smart infant cradle” is designed as an automated cradle that operates on sensors.  Whenever a baby cries, sensors will get activated. This cradle is mainly designed to console a  crying baby and put it to sleep without the presence of parents. This system consoles the baby’s cry and it makes the baby sleep. It is designed in such a way that it works with a mobile app, which allows the parents to ON and OFF the cradle and also overrides its automated functions. This cradle  system  allows  the  parents  to monitor  their  babies from their place of work

PROPOSED SYSTEM:

This project was designed as 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. The system utilizes IOT technology comprising of Modules like Raspberry Pi, Arduino, Humidity & Temperature sensing providing features such as Swing Automation, Cry Detecting Mechanism, Live Video Surveillance, Cloud Computing (Data Storage) & User-Friendly Android Mobile Application (for User Controls). 

IoT-BBMS: Internet of Things-Based Baby Monitoring System for Smart Cradle

In order to detect each & every activity of Baby, different Sensors/Modules are attached to the Cradle: Humidity & Temperature Sensing Module for detection of Wetness of the bed, A Camera on top of the Cradle for live video footage & Cry Detection Circuit to analyze Cry Patterns which eventually triggers the swinging mechanism (if required based on the range of frequency). 

All the data which has been taken from the sensors/modules will be stored in Cloud (Google Firebase) & analyzed at regular intervals. Moreover a  Health Algorithm is applied to these datasets to get information about the regular symptoms

BENEFITS OF SMART CRADLE SYSTEM

  • Video Enhancement
  • Instant Mobile App Notification
  • Better Monitoring of Baby
  • Automation of System
  • Real-Time Database
  • Accurate Sensors
  • Cry Analysis Pattern
  • Analog to Digital Conversion

SYSTEM ARCHITECTURE

HARDWARE REQUIRED:

  • Arduino Mega:

The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. 

  • Wet Sensor 

In older days there was no wet detection system, so baby skin gets wet and there are chances of getting allergies, rashes. So we came up with the idea to use a moisture sensor to detect wetness on the baby diapers. This system gets notified when the diaper is wet. And sends messages to parents.  

  • Sound sensor module:

A sound sensor is used to detect the cry of a baby.  It quantifies the intensity of noise. Microphone finds the infant weep auditory sensation when toddler weeps in the cradle and after which it is changed to the electrical signal

  • Temperature and humidity sensor

A temperature sensor is designed as an electronic device that measures the temperature of its environment and converts the input data into electronic data to record monitor or signal temperature changes.The DHT 11 is a low-powered electronic device that lets us get the value of the temperature and the moisture. The sensor consists of a capacitive humidity sensor and a Thermistor connected to a high-performance 8-bit microcontroller. .

  •      GSM Module:

This Module is used to establish communication between a computer and a GSM system. Global System for Mobile communication (GSM). This is an architecture used for mobile communication. The GSM module sent messages to the parent’s phone when the cradle gets wet or when the baby doesn’t stop crying for a specific time.

  • 12V DC geared motor: This 12V DC Geared Motor designed asa high torque widely used for industrial applications. They offer a wide range of applications makes it perfect for DIY project makers as well as small business machines.
  • PIR Sensor:

A Passive Infrared sensor is defined as an electrical sensor that detects the infrared light radiated by a warm object or used to sense motion. It is widely used to detect the motion of a human body within the sensor’s range. Hence often referred to as “PIR”, “Pyroelectric”, “Passive Infrared” and “IR Motion” sensor.

CONCLUSION:

This Proposed system on Intelligent Smart Cradle System using a Sound sensor, Wet sensor, PIR Sensor, GSM Module, and Arduino Mega microcontroller modules is a cost-effective and efficient system designed for real-time monitoring of toddlers utilizing Internet of Things (IoT) technology. This system continuously monitors the Toddler’s movement and if anything unusual occurs, the system will inform the parents via SMS through Mobile phone. This system also provides functions such as a Camera on top of the Cradle for live video footage & a Cry Detection Circuit to analyze Cry Patterns which eventually trigger the swinging mechanism. Moreover a Health Algorithm is applied to these datasets to get information about the regular symptoms
