Where do they get temperature sensors for connecting to a PC?

Question

Do it yourself

Hello!
I want to measure the temperature of a heating radiator and receive data on a computer (ideally, of course, they would be sent to the Internet, but this will probably be much more expensive than I imagine).
I am unfamiliar with a soldering iron, so I would prefer a device that I imagine as follows: a pip at the end of a usb cable that can be stuck to a hot battery, and the data can be read, say, from some log file.
Search for snouts, but there are either thermal sensors separately, as components, or some kind of weather stations.
I would be grateful for any finds.

Answer 1

I took it on ebay, searched for the phrase usb thermometer , the quad sensor cost about 60 dollars. The software is scary, but it performs the task of logging.

Answer 2

There is a desire for yourself - Arduino + sensor (LM135, as an option).
No desire - www.dealextreme.com/p/temper-usb-thermometer-temperature-recorder-for-pc-laptop-81105?item=2

Answer 3

is this what it looks like?

Answer 4

There were many articles about this, for example habrahabr.ru/post/141713/
In short - a one-wire USB bus adapter, we hang on the bus as much as necessary with a temperature sensor like DS1820. There are also temperature and humidity sensors.
