Advanced Health Wearables: COVID-19 Detection Eyewear
As society adapted to life during a pandemic, the need for hands-free, non-intrusive monitoring became paramount. This project takes health technology from the pocket to the face, creating a pair of smart glasses designed to identify nearby environmental heat signatures associated with fever—a key symptom of COVID-19.
Intelligent Thermal Scanning for Personal Safety
The "Eyeware" system utilizes a high-sensitivity DS18B20 sensor mounted on the frame to read the temperature of the immediate surrounding air and objects.
- Range Calibration: The device is tuned to detect the peak temperature within a 1-meter radius.
- Clinical Threshold: If a heat source above 38.0°C (100.4°F) is detected, the device enters an alert state.
- Dual Feedback: The wearer is instantly notified via an onboard Piezo Buzzer as well as a push notification sent to their smartphone.
Connectivity and Mobile Integration: MIT App Inventor 2
Leveling up from a basic stand-alone alarm, this project incorporates the HC-05 Bluetooth Module. This allows the glasses to communicate with a custom-built Android application created in MIT App Inventor 2.
- Real-Time Dashboard: The app displays a live feed of the highest detected temperature and the current safety status.
- Interactive UI: Users can see historical alerts and monitor connections in a user-friendly interface.
- Smart Notifications: Leveraging the smartphone's built-in alert system ensures the wearer never misses a critical warning, even in noisy environments.
Evolution of Durable Prototyping
The project went through a rigorous development cycle. The initial "fragile" prototype was refined into a "Stage 2" design that prioritizes durability and wearer comfort. By moving away from loose jumper wires to soldered connections and secured mounting, the device is now capable of surviving the daily rigors of a school day or a commute.
How did the idea originate
The idea came to me when I got to know that schools would reopen after lock down so to be sure that I would be safe from corona virus I created this project to alert me whenever a carrier of corona is around me.
Working of the project
The project has a ds18b20 sensor which will provide the highest temperature within 1 meter of range and if the temperature exceeds 38*C then the device will send a message on the mobile phone and it will also ring a buzzer to notify the user.
How was this project made
This project was built in two stages, in the first stage it was a simple circuit which sent notifications via bluetooth to a mobile phone and the app only showed the notification and the project was also very fragile. In the second stage the project is very durable and to notify the user of corona virus the device uses a buzzer and an in-mobile notification to notify the user of close range contact with a COVID-19 suspect. The app in the second stage also has an interactive user interface and it also displays live temperature and status of contact with a COVID-19 suspect.
