Thermometer
Overview¶
The Thermometer is a decorative wall-mounted device that displays the temperature of its surroundings, based on the biome and the adjacent placed blocks. It works just like a wall torch, requiring a supporting block behind it.

Temperature Display¶
The Thermometer displays the current temperature through its glass, and can also be displayed on screen when looking at the block.
This feature can be enabled or disabled through the F3 + F6 debug options. It is enabled by default.

Redstone Output¶
The Thermometer emits a redstone signal based on its current temperature.

Extreme temps
Due to the extreme temperatures at these dimensions, the Thermometer does not work and emits no signal in the Nether or the End, though it will still display the temperature.
