Let's Code ESP8266 0x03: Temperature and Humidity sensor BME280

In this episode the BME280 humidity and temperature sensor gets added to the mix and we switch libraries around. I chose the Sparkfun libraries, because they work together quite well, are open source and support both the BME280 and the CCS811 CO2 sensor.

When buying hardware, make sure to buy 3.3V versions, since the ESP talks 3V, or you will have to use level shifters. Sparkfun sells the necessary modules, but for about 20 USD each. From china you can also get clones for around 5 USD. Quality may vary, Sparkfun will supply of course reliable modules.
