In a world grappling with the COVID-19 pandemic, Open Green Energy rose to the challenge by developing a battery-powered portable thermometer. This ingenious device, aptly named “Fever Finder,” is designed to detect elevated temperatures and alert others, acting as a vigilant guardian against the spread of infection.
iRobota’s Symphony of Sensors
At the heart of Fever Finder lies the iRobota Nano, a compact yet powerful microcontroller. Like a maestro, it orchestrates the symphony of sensors, processing and interpreting their data to provide accurate temperature readings.
GY-906: The Temperature Sentinel
The GY-906 module stands as the sentinel of temperature, equipped with an infrared (IR) sensor. This vigilant sensor continuously scans for elevated temperatures, acting as an invisible shield against the threat of infection.
OLED Screen: A Clear Window to Health
The 0.96-inch OLED screen serves as a clear window to health, displaying temperature readings in bold, easy-to-read digits. With a quick glance, users can assess their temperature and take appropriate action.
IR Emitter/Receiver: A Beacon of Detection
The IR emitter and receiver duo act as a beacon of detection, constantly scanning for the presence of a person. When someone enters the device’s vicinity, the IR emitter sends out a pulse of infrared light, and the receiver stands ready to capture its reflection, confirming the presence of a potential subject for temperature measurement.
LEDs: Illuminating Health Status
A pair of LEDs, one green and one red, serve as visual indicators of health status. When the temperature reading falls within the normal range, the green LED glows reassuringly, signaling all is well. However, when the temperature crosses the threshold into fever territory, the red LED springs into action, issuing a warning.
Buzzer: A Sounding Alarm
The buzzer acts as a sounding alarm, emitting a piercing tone when the temperature reading exceeds the predefined threshold. This auditory alert ensures that even in noisy environments, the user is promptly notified of a potential fever.
Bonus: DIY Fever Finder – A Community Shield
The Fever Finder project is not just a technological marvel; it’s a symbol of community resilience. Open Green Energy has made detailed instructions and a comprehensive project write-up available on Instructables, empowering individuals to build their own Fever Finders. Additionally, a video tutorial on YouTube provides step-by-step guidance, making the project accessible to makers of all skill levels.
This open-source approach allows communities to take ownership of their health and safety, creating a network of Fever Finders that can help contain the spread of infection. By working together, we can turn this DIY project into a powerful force for good, protecting our communities from the invisible threat of COVID-19.
In the face of adversity, the Fever Finder stands as a testament to human ingenuity and the power of collaboration. It’s a beacon of hope, reminding us that even in the darkest of times, we can rise to the challenge and create solutions that protect and empower our communities.
