GuardianBeam is a palm-sized, non-invasive safety beacon designed to provide 
continuous, contactless vital sign monitoring, aligning with Sustainable Development Goal 3: 
Good Health and Wellbeing. The project addresses a critical gap in current monitoring 
systems, which often require physical contact or lack real-time emergency alerts for events 
such as respiratory distress, sudden falls, or children left unattended in vehicles. By bridging 
these gaps, GuardianBeam offers a proactive solution for vulnerable groups, including 
infants, bedridden patients, and the elderly. The system employs ultra-wideband (UWB) 
radio waves to detect subtle chest movements and heartbeats from a distance of up to two 
meters. This methodology utilizes an ESP32-C6 microcontroller and a non-contact heart rate 
and respiration sensor to analyze physiological signals. The architecture integrates Home 
WiFi Router to connects the device to the internet. Key findings demonstrate that the system 
accurately monitors heart rates between 60-150 bpm and respiration rates between 10-25 
bpm, providing reliable data with a radar angle of 100o x 100o. The project has reached 
Technology Readiness Level 7 (TRL 7), confirming its functionality as a portable, USB
powered prototype in operational environments. In conclusion, GuardianBeam enables 
remote, real-time monitoring via the Favoriot IoT Cloud and Telegram API Bot, ensuring 
caregivers receive immediate alerts during critical events. The significant impact on the 
community lies in its ability to offer unprecedented peace of mind through a non-intrusive 
monitoring solution. Prototypes were tested across simulated hospital rooms, homes, assisted
living flats, and vehicle interiors, achieving a 90% accuracy rate in identifying anomalies, 
with alerts triggered within 5 seconds and a false-positive rate below 6%. By setting a new 
standard for preventive care and automotive safety, GuardianBeam ensures timely life-saving 
interventions for those most at risk.
