Experience

Environmental Monitoring App

This project is a network of inter-integrated circuit (I2C) sensors that gather information about the local environment. I was tasked with building the embedded C code used to sample sensors, store metrics on an SD card, and reply to requests over Bluetooth Low Energy (BLE) to provide information used to render different views of the data.
