- Mon Mar 30, 2015 11:33 pm #13084 I am surprised that there are no simple temperature and humidity sensors based on the ESP8266 listed.

I have found similar designs, but they also involve an Arduino type device in the circuit.
Example: http://www.instructables.com/id/ESP8266 ... ty-logger/

I thought the ESP8266 along with only a DHT22 temperature and humidity sensor and a few passive components would have been all that is required, or am I missing something here?

I made a temperature logger with a DHT11 + ESP8266(-01) + USB 3.3v power. Very simple with the nodemcu firmware and some pieces of code I found on the net. https://thingspeak.com/channels/29692
DHT22 is more accurate than DHT11.

I used one of these modules

And didn't need any pull-up resistors on the pcb.
