Arduino driver for CCS811 digital gas sensor

SEN5X to RS485

Sending measurement data(eCO2, TVOC, temperature and humidity) from CJMCU-8118(cheap chinese board with CCS811 and HDC1080) to your InfluxDB database.

This is a small sketchbook for a voc (eco2, etvoc, temperature and humidity) sensor. It uses a NodeMC ESP8266, DHT22, CCS811, an OLED Display, a red LED and a switch.
