Simple-Dust-Sensor

A simple dust sensor to monitor the clean room, utilizing 7-seg displays and a wifi-connected microcontroller

Software Development

• This project utilizes PlatformIO, an extension for VS Code. Install PlatformIO and open the VS Code workspace file in this repo to get started.
• Duplicate the include/wifi_credentials.sample.h to include/wifi_credentials.h, and fill the credentials to maintain wifi connectivity.
• The microcontroller is an ESP32 devkit, and can be programmed over USB from PlatformIO.

Wifi Interface

• This project displays the current and max dust values on the device itself, and also relays them over a network to view logs/a graph over time.
