That's a fantastic project you're going to do. Okay, so for a stand-alone project like that, to be honest with you, you might get by with the Raspberry Pi Zero W. It's small, cheap, and perfect for little things like reading temperature and controlling a relay. You'll definitely need that temperature sensor (DS18B20 is a good one, a popular option), a 5V relay module (make sure it's rated for the power of your freezer!), and some jumper wires to connect things. As far as the specifics go, find libraries or tutorials that accommodate your sensor of choice and relay – makes the coding part a little easier!
