Outdoor Temperature Sensor

[Plummet]

I am looking for the ability to see, on my iMac, the temperature outside my home. I currently have a La Crosse Technologies weather station that uses an outdoor sensor for the indoor display. I would like to replace that with a simple, inexpensive sensor that will report to my iMac. I am NOT looking for one that reports via app to an IPhone or iPad. I did search but didn't find simple. Any help?

Thanks!

Not sure if it's the answer to your need butI did once use a raspberry pi with various sensors fitted, which would feed information back to my iMac.
