/*
This is the code for the AirGradient DIY Air Quality Sensor with an ESP8266 Microcontroller.
It is a high quality sensor showing PM2.5, CO2, Temperature and Humidity on a small display and can send data over Wifi.
For build instructions please visit https://www.airgradient.com/diy/
Compatible with the following sensors:
Plantower PMS5003 (Fine Particle Sensor)
SenseAir S8 (CO2 Sensor)
SHT30/31 (Temperature/Humidity Sensor)
Please install ESP8266 board manager (tested with version 3.0.0)
The codes needs the following libraries installed:
"WifiManager by tzapu, tablatronix" tested with Version 2.0.3-alpha
"ESP8266 and ESP32 OLED driver for SSD1306 displays by ThingPulse, Fabrice Weinberg" tested with Version 4.1.0
If you have any questions please visit our forum at https://forum.airgradient.com/
Configuration:
Please set in the code below which sensor you are using and if you want to connect it to WiFi.
You can also switch PM2.5 from ug/m3 to US AQI and Celcius to Fahrenheit
If you are a school or university contact us for a free trial on the AirGradient platform.
