ESP8266 Community Forum

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.

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 should add that i first made it with only wires between the pins, but then made a pcb. You can order here: (I get 1$ credit if you do)

I used one of these modules

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

Havn't see this similar product in the market.
