For many sensor applications it would be of great use to have an adc on the chip.

But from what I have seen so far, I came to the conclusion that the esp8266 does not have adc.

Did anyone see something different?

Regards

Their demo boards use this MEMS temp/humidity sensor with an I2C interface.
