From the project

gas sensing iot device(nrf52832)

Firmware version 1.0.2 for HHS's portable industrial gas monitor. The application runs on a custom nRF52832 board, measures multiple gases, and transmits real-time readings over Bluetooth® Low Energy. Environmental data is fused with the Bosch BSEC2 library to provide indoor air-quality indicators in addition to electrochemical gas concentrations.
