This project presents a low-cost, portable hydrogen sulfide (H₂S) monitoring device designed to measure real-time exposure among Sargassum cleanup workers and coastal communities. Built on open-source hardware (Arduino MKR Zero), it integrates an electrochemical sensor, OLED display, RTC, and microSD data logging. Its modular, design enables continuous environmental health monitoring in remote or resource-limited settings.
