How to measure: Temperature & humidity

In my project I use DHT11.

The reason is the speed - when you ask the sensor, you get the temperature (and humidity). For sure - 1wire & dallas are great, but you need to wait for a while...therefore it is not implemented (yet :-).

Arduino scheme

1) dht11

You need to power DHT +5V : 3.3V is not enough and it is not working!

2) 1wire - dallas

Easy to add one or more temperature sensors. You need to add 4.7k resistor.
