Yes, it's a brick.
If you want to get fancy, you can also add a webcam to the set-up but the brick is pretty essential. The main condition is that it has to be located outside with no shielding from the elements.
How does it work ? Three conditions can be embedded in two bits of information.
- If the brick is dark brown, it's a sure sign that it's raining outside.
- If the brick is bright, then it's sunny outside.
- If the brick is not there anymore, it's a tornado.
