IOT Based Patient Pneumonia Monitor
Project Area of Specialization Internet of ThingsProject SummaryPneumonia has been labelled as the single largest cause of child mortality for the children under five in developing countries around the world. We propose a method to continuously monitor parameters like Respiration Rate, Heart Rate, Blood Oxygenation (Spo2) and Body Temperature in a noninvasive and nonobtrusive manner behind the ear. The device used is a low cost Bluetooth-based, ear-worn multi-parameter monitoring platform. The data is streamed using WIFI to attendants smartphone or a smart gateway device which uploads it to the server.
The device also enables doctors to track if medication is effective by seeing changes in various physiological parameters. For the measuring of parameters multiple sensors are used. This will enable health workers in rural areas that are extremely understaffed to assist more children. The device also have alarm modes to alert doctor of sudden onset of fever or difficulty of breathing.
Project ObjectivesLearning of the traditional way of diagnosing and monitoring pneumonia and the death rate due to this disease in children we propose a novel method to monitor pneumonia wirelessly in low-cost.
- To design and develop a low-cost, low power, wearable multiparameter sensor for pneumonia diagnosis and monitoring.
- Development of a system for doctors to remotely monitor the child by sending data to the cloud through a WIFI with a mobile phone as a gateway device.
- To reduce the mortality rate of pneumonia, by early detection and timely treatment.
- To help community healthcare workers in assessing and treating children in low to medium income countries.
- To monitor vital parameters like respiration rate, SpO2 levels, heart rate, body temperature of a child noninvasively and nonobtrusively to enable rapid diagnosis wirelessly.
- To monitor parameters through sensors can provide insight into effectiveness of medication.
The model which we are using in this project is the prototype model.
- Reduces development time and costs as the errors, bugs and defects can be detected much easier.
- Requires user involvement. Increases the user involvement even before implementation.
- Missing functionality can be identified easily.
- Encourages innovation and flexible designs.
- Results in higher user satisfaction as quicker user feedback is available leading to better solutions.
- Specifications can be developed incrementally.
- Scope for accommodating new requirements.
- Part of the product is visible at early stage.
- Allows instances to inherit run-time state from other instances and inheritance to be changed at run-time, by making parents slots assignable.
Since in this methodology a working model of the system is provided, the users get a better understanding of the system being developed.
- When prototype is shown to the user, he gets a proper clarity and fell of the functionality of the software and he can suggest changes and modifications.
- It reduces risk of failure, as potential risks can be identified early and mitigation steps can be taken.
- Time required to complete the project after getting final the SRS reduces, since the developer has a better idea about how he should approach the project.
- secure server and the data could be presented intuitively to a doctor.
- We have demonstrated that use of noncontact temperature sensors would be a viable way to monitor respiration.
- A powerful microcontroller is used for interfacing various sensors. A lithium polymer battery is used to power the prototype.
- The comfort of the child was the priority while designing this device. If the design is obtrusive, the usage will be limited. So this device is designed with MCU, wireless unit and battery behind the outer ear helix to provide high degree of comfort.
- The system would be inexpensive due to the low bill of materials cost and would be light to wear at 38 grams.
- The data is viewed through graphs and doctor can set specified alerts for each parameter. If the data crosses a set limit, the doctor is alerted and the data id highlighted in graph.
- Due to the portability of device it would be way easier for doctors and health care workers to diagnose and monitor pneumonia in hospitals as well as in remote areas which are highly understaffed and allows to treat more patients in less time .

- Respiration Sensor
The variation of the nasal temperature is measured accurately using the MLX90614 noncontact infrared temperature sensor which is pointed to the nasal passage
- Heart Rate and Blood Oxygenation Sensor
Photoplethysmography (PPG) and Pulse Oximetry (SpO2) are carried out by a single sensor which is used to measure reflectance of three LEDs of different wavelengths.
- Body Temperature Sensor
The body temperature was also measured nonobtrusively by checking the ear canal temperature using the LMT70 temperature sensor.
- Activity and Sleep Sensing
An ADXL345 accelerometer is also used to provide activity and sleep data of the child. The technique of actigraphy is used to continuously record the motion data.
- STM32F205 Microcontroller
A powerful STM32F205 microcontroller is used for interfacing various sensors.
