I’ve built a couple of DHT11 wifi gadgets with ESP boards. Fair warning: they are not very accurate except in mild / middle temp ranges. When it gets too cold or too hot their readings can get way off the mark.
Here’s some other people complaining about them: forum.arduino.cc/t/dht11-accuracy/373416
At least they are cheap. If you want a basic temp / humidity sensor, it will do that but I wouldn’t use it for anything crucial.
