Wind Chimes:

Wind chimes are crafted from gold and amethyst shards. They look like a gold plate, with 4 amethyst crystals hanging from gold chains. They must be placed under a block, similar to a lantern.

They make a quiet chiming sound, which grows louder during rain and a few minutes before when it gets windy.

Detecting Weather:

5 minutes before it rains, wind chimes will begin making a louder chiming sound. The sound is louder if it will thunderstorm. This keeps happening until the rain stops.

They also emit a redstone signal to the block above them when making sound. The strength of the signal depends on the type of weather, and if it's predicting rain or currently raining.

Detecting Entities:

If an entity is inside the block space of the wind chime, it will make a louder chiming sound and emit a redstone signal.

Putting an armor stand inside a wind chime would create some extra ambient sound. It would also work as a ceiling mounted wooden pressure plate.
