Welcome to the IoT4AQ Wiki!

Introduction

Part of the IoT4AQ project was a 2 day hands-on workshop during which a simple Air Quality system is assembled. It consists of

• a ESP32-DevKitC WROOM CPU
• a DHT11 temperature and humidity sensor
• a PlanTower PMS5003 dust sensor
• a DS3231 Real Time Clock module with an AT24C32 serial EEPROM
• a LCD2004 character display with I2C interface
• a SD card reader

At first a very basic review of the C++ programming language and the Arduino SDK is given. After that, small evaluation programs for each of the above devices are developed and finally the code is combined into a full system.
