AirGradient Arduino Library for ESP8266 (Wemos D1 MINI)
=====================================================================================================

Build your own low cost air quality sensor with optional display measuring PM2.5, CO2, Temperature and Humidity. 

This library makes it easy to read the sensor data from the Plantower PMS5003 PM2.5 sensor, the Senseair S8 and the SHT30/31 Temperature and Humidity sensor. Visit our DIY section for detailed build instructions and PCB layout.
