From the project
a modular smart helmet device.
Ceremet is a custom hardware and firmware solution built to transform any standard helmet into a smart helmet. Originally created during the Genesis Hackathon, this project encompasses a custom-designed PCB, ESP32-based firmware, and a modular architecture.
Note: The firmware is currently undergoing optimization.
