Smart Social-Distancing Wristband
My first industrial project, run solo from hardware to design to software. Built at Mayfly for Bursa Ekol College — an ESP32 + C++ wristband measuring distance to cm precision.
Overview
A smart wristband we produced at Mayfly for Bursa Ekol College during Covid-19. I ran the entire process — hardware selection, mechanics/design and embedded software — single-handedly; it is my first industrial project (real, fielded use for an actual customer).
How It Works
I programmed the ESP32-based wristbands in C++ and, with a custom algorithm, detected the distance between two or more people wearing the same band to cm precision. When users broke the safe distance, the band gave vibration and audible warnings and showed an alert icon on screen.
Outputs & Versions
I produced two versions: the first (in the gallery) and an improved second version (the square-screen model on the cover). Beyond distance alerts I added step, heart-rate and temperature measurement, plus smartwatch features like clock, weather, navigation and alarm.

Building a wearable / IoT product?
I develop ESP32-based wearables and embedded devices with custom C++ algorithms — hardware to software, single-handed.
