Hello

You can use a DHT11 to measure temperature and use a relay to switch on fans and ac if thats what you meant.
Also how do you plan to control the house temperature. You can't control temperature using sensors. Sensors just Sense :lol:

The DS18B20 sensor is easier to interface, it just requires one 4.7K resistor and the drivers are built in to Raspbian, they just need enabling through the configuration program (1-wire).

There are full suites of home automation packages that can run on the Pi.

For example https://www.openhab.org/

Though this may seem overkill, they give you a good base to grow as time goes by.

One big thing to consider is that you may be handling mains voltage at some point and are you qualified to do so?

Wired or Wireless?
..the only thing worse than a stupid question is a question not asked.
