Smart Monitoring and Security System for Infants

Project Title

Smart Monitoring and Security System for Infants

Project Area of Specialization Wearables and ImplantableProject Summary

In Hospital Nurseries, Nurses usually take care of Infant’s health and the abnormalities of the Infants, but nurses are not available all the time for observing the child. Sometimes, In the absence of hospital nurse, abduction of the Infant take place by the kidnapper and sometimes Child’s health becomes abnormal. Different Monitoring Systems for the Infants utilized various wireless technologies, but these wireless technologies like Wi-Fi, Bluetooth, etc contain radiations that are very destructive for the Infants. After considering all the critical consequences regarding Infant’s Health and Infant’s Protection, we are developing such a Robust Wireless Li-Fi based Health Monitoring and Protection System for the Infants that will efficiently monitor Infant’s Health and Presence. Li-Fi as compared to other Technologies, it can be utilized for the wireless transmission of data near Infants because light is naturally safe. Hence, Infant’s Health and Protection can be monitored 24x7.

Project Objectives

1. We are developing such a robust system which will keep an eye on Infant Abduction by introducing li-fi based security system

2. Our system will efficiently monitor different parameters of Infant’s health, such as

• Heartbeat
• Temperature
• Oxygen Level

3. Li-Fi as compared to other technologies, light is naturally safe and can be used in areas where Radio Waves are often considered problematic such as in hospitals

Project Implementation Method

The project “Smart Monitoring and Security System for Infants” is based upon Sensors, Controllers, and Li-Fi Transmitter & Receiver.

The first and important part of our system is sensors. Sensors can be attached with the Infant's for continuous monitoring of an Infant’s health. DS18B20 and MAX30100 sensors used for Infant's health monitoring.

Data comes from the sensors are fed into Lilypad Arduino which is specially used for wearable devices. Sensor’s data are in analog form. Firstly, we have to convert the sensor’s data into digital form, that can be done through the LilyPad Arduino because it has built-in Analog to Digital converters. After conversion of the data into digital form, then this data is fed to the Li-Fi transmitter for the wireless transmission. Li-Fi transmitter consist of a switching circuit, that will quickly switch on and off the lights then data can be send through LED lights.

Solar plates are used to receive the data from Li-Fi transmitter. Solar plates will convert the data into electric signal then it is fed to LM339 IC.

LM339 is used in the receiver’s circuitry. It will adjust the coming voltage to 5 then it will fed into the Arduino. And arduino ethernet shield is used to upload the data into web server.

Now, data is compared with the normal parameters, if any abnormal condition occurs then respective department will be notified.

Benefits of the Project

1. Smart Monitoring and Security System for Infants can be used to monitor the health of the Infants and it can timely inform the doctor if any abnormal condition occurs.

2. It can also be used as a protection system, if anyone tries to kidnap the Infant then it will timely inform the security guard.

3. Li-Fi Technology provide radiation free environment to Infants.

4. It can also be used in day care centres and for patient monitoring in Homes.

Technical Details of Final Deliverable

1. Li-Fi Technology:

    The range of our Li-Fi Transmitter and Receiver is 8 metres and it is basically Multi-point to point communication. Its baud rate is 9600 bps. BC-547 NPN Transistor is used for the switching of LED lights. Solar Plate is of 5v.

2. Sensors:

MAX30100 is an integrated Heart-Rate and Pulse Oximetry monitor sensor that combines a photodetector, optimized optics, low-noise analog signal processing, and two LEDs. MAX30100 is especially designed for wearable devices and medical monitoring devices. Heart-Rate and Pulse Oximetry will be calculated when the finger is placed on the tip of the sensor.

DS18B20 is a temperature sensor consist of steel Nozzle and attached with the infant to measure temperature of the infants. It has three terminal such as red (5v), black (ground) and yellow (data). The sensor has tolerance accuracy of ±0.5°C.  It is usable with 3v to 5v. its accuracy is more at long distances because it did not produce signal degradation as it has 12bit digital configuration.
