While exploring the world of connected things (a.k.a. #IoT) the ESP8266 popped up as an new platform for measuring and sensing data - making Things becoming more relevant. SENSable Things are starting to sense our environment, while feeding data to a cloud the question comes up: what should I read out of the values?

Did you know that VOCs (volatile organic compounds) are emitted by bread? Fresh bread smells not only to us - it has a meaning to VOC sensors, fresh bread smell like value 170! Or can you sense  the air in your house - when and how long you should open windows? ...

Even we build on ESP8266 the first prototype was on BLE /"Platinchen"

But let's first dig into the hardware part:
