ESP32-based portable blood glucose monitor with e-ink display. Inspired by gagebenne/pydexcom and lmarzen/esp32-weather-epd.
SugarSentry is a portable device that displays blood sugar levels from the Dexcom API, shows historical data in a graph, and also monitors room temperature and humidity (because why not). The device uses an e-ink display for low power consumption and long battery life. For nighttime use, it features a proximity-activated RGB LED that dimly indicates the current blood sugar level.
