Template:BlockTileEntity
A Daylight Sensor is a block for use with redstone circuitry, added in the Redstone Update. It works like a solar panel, emitting a redstone signal if it is bright enough (sunlight level) to do so. The strength of the redstone signal varies by the time of day. For example, the sensor will emit redstone for 15 blocks at midday but roughly 5 blocks at evening. The daylight detector emits a redstone current to any/all blocks placed directly (within 1 block) above/below/next to it.
If the Daylight Sensor has an opaque block above it, then it will emit a weaker signal, or none at all, as it is directly proportional to the sky light, which can be useful for controlling light levels with redstone lamps and pistons to cover and uncover the sensor. Using a NOT gate (also known as an inverted Redstone signal) can reverse the sensor's signal, creating a "night sensor." This can, for example, allow redstone lamps to come on at night and off during daytime or a bunker that locks itself at night using the reverse signal and sticky pistons.

Uses
As a night time detector
The simplest NOT gate that can be created. The redstone lamp will turn on during the night, and turn off at sunrise. The block in the middle can be anything on which a Redstone Torch can hang (Except for a Redstone Block).
By connecting the sensor to a NOT Gate(inverter), it will output a signal when the light level is LESS than 4, so you can, for example, make lights that turn on at night, or gates that automatically close.
You can also detect moonlight by blocking off the detector so it cannot see light, then pointing a comparator away from it.
As Decoration
Sensors may be used solely for decoration.
As a clock
Because you can measure exactly what light level it is, you can make a clock. For example, for every light level it is, 1 light goes on a board. When it is night, the word "Night" is illuminated on the board displaying light level or time. This can be useful for servers, especially if you do not have the ability to create one using piston memory, or do not wish for one as it can be complicated or laggy.
As a timebomb
The daylight sensor can be placed atop TNT unlike most redstone devices. If planted at about midnight, this can make for an excellent timebomb, as the TNT will be ignited when the sun rises. Since the skylight is measured, which is shadowed out by blocks above, the sensor on TNT can be used in traps for players breaking the (e.g. ore or cake) blocks above the sensor. The Daylight sensor bomb can be rigged to go off at different times. If you want it to go off during the day, wire redstone to the TNT from the daylight sensor. While you can just place the sensor on top of the TNT, the TNT will glitch, and you will see the TNT go above the daylight sensor. If you want a bomb to go off during the Night, You will need a NOT-Gate (See NOT gate), but other than that, its the same. For a bomb to go off at noon, you will need a comparator. The Daylight sensor will go through the TNT, but since the lever is always full power, and the daylight sensor gets best power at noon, the bomb will go off at noon.
Timed jingle
Using some note blocks and redstone circuitry, you could make a set jingle that plays at certain times of the day, such as a device that warns you that nighttime is over, or is beginning. This could be used as a sort of morning alarm if you do not use a bed.
As a signal
The daylight sensor can easily be used to signal things at different times of day. With command blocks in the game, it can do many more things, like broadcast messages or change everyone's gamemodes (For whatever reason). Below are different methods for it.
Mining signal
If you are mining and you want to come up at a time of day, you can connect the day light sensor and make it either send a redstone pulse down your mine or broadcast a command block message.
Command block command for message:
/say <message>
NOTE: On servers this will broadcast a message to the entire server. So use this command:
/tell <your name> <message>
As a server signal
Message
You can send out a message to the entire server at a certain point of day. The command block command for this is:
/say <message>
OR
/tell <player> <message>
First broadcasts a message to the server, second one tells a message to a player.
As a Weather Monitoring Station
Using an old fashioned redstone clock that is synchronised with the Minecraft day that is broken up into segments according to the daylight sensor power output schedule, it is possible to use many daylight sensors to build a rainstorm and thunderstorm detector. Use a comparator to reduce the redstone clock's signal strength to below that of the daylight sensor's clear day output. Wire this into the side of another comparator that has a daylight detector wired to the back. The wire coming out of the end of the comparator will deactivate whenever there is a storm. Using this you can detect both rain and thunderstorms using two lines with adequate comparator sensitivity. Using this you can signal an alarm whenever there is a storm, count the number of storms, count the duration of the storms using another clock and some type of memory, and even all three.
Output
These tables link output values to the time they occur as well as co-occurring light levels. Note that while the sensor responds to changes in light level, the light level only modulates a separate scale that more or less follows sunlight. This modulation does make the tables invalid if the sensor doesn't have a direct view of the sky.

'''Flint''' is a mineral obtained from [[gravel]].
== Obtaining ==
=== Mining ===
When a block of [[gravel]] is mined, there is a 10% chance for a single piece of flint to drop instead of the [[gravel]] block. When mined with a [[Fortune]]-enchanted tool, this chance increases to 16% at Fortune I, 25% at Fortune II, and 100% at Fortune III. Gravel mined using a tool with [[Silk Touch]] or gravel that fell on a non-solid block never produces flint.
=== Trading ===
Novice-level [[Trading#Fletcher|fletcher]] [[villager]]s have a 50%{{only|bedrock}} or {{frac|2|3}}{{only|java}} chance to offer 10 pieces of flint for 10 blocks of gravel and an [[emerald]].

Issues
Issues relating to "Daylight Detector" are maintained on the bug tracker. Report issues there.
Trivia
- Daylight Sensors only work by sunlight and cannot be activated by other light sources such as luminescent blocks or torches.
- Daylight Sensors are less than a slab tall, which is like redstone repeaters, redstone comparators and trapdoors.
- A daylight sensor connected to a powered dispenser via redstone wire will cause the dispenser to fire every time the light level changes.
- Rain will affect the sensor.
- Daylight Sensors, as well as most redstone technology, appear more similar to modern technology compared to most other blocks.
- Daylight Sensors can be used as fuel in furnaces.
- Due to the fact that a covered sensor gives output at night, it is possible to create a 24H Redstone clock that is synchronous with the Day-night cycle, that still works during the night.
- If you are playing an old world and still have plain wooden slabs from before wood types were differentiated, note that these slabs will not work in the crafting recipe for the daylight sensor.
