Daylight Sensor

Daylight Sensors are Redstone-related blocks that were added in Update 0.13.0, and produce a redstone signal based on the amount of sunlight it receives.

Crafting

 * 3 Wooden Slabs + 3 Glass Blocks + 3 Nether Quartz Blocks => 1 Daylight Sensor

Uses
Daylight Sensors are mainly used to produce redstone signals in proportion to the amount of sunlight and moonlight.They can also be used as fuel in a furnace, and last for 1.5 operations. They can be inverted by tapping on it.

Regular
Regular Daylight sensors activate when exposed to a sufficient amount of sunlight, or when the sky light level drops to 0.

Inverted
Daylight Sensors can be 'inverted'. During this mode, they activate only when the sunlight level is low enough.

Trivia

 * Daylight Sensors cannot be activated through artificial light sources (Like Torches).
 * Since the signal is directly proportional to the sunlight (or inversely in 'Inverse Mode'), if a block is placed above it, it will not function.
 * Daylight Sensors have a thickness of 3/8 of a block.
 * If you tap a daylight sensor, it will go into night mode, where it turns on at night and off at day.
