Daylight Detector

A daylight detector[a] is a block that outputs a redstone signal based on sunlight.

Using it inverts it, causing it instead to output a redstone signal based on the darkness of the sky.

Obtaining

Breaking

Daylight detectors can be broken fairly easily by hand, but can be broken faster by using an axe. Inverted daylight detectors cannot be collected directly; they drop a regular daylight detector. In Bedrock Edition, the inverted sensor may be obtained via inventory editing or add-ons.

Usage

Redstone component

Graphed daylight detector output in clear weather.
See also: Redstone circuit

A daylight detector can be used to produce redstone power in proportion to the daylight cycle.

A daylight detector is 0.375 blocks high (3/8ths of a block). Daylight detectors can be moved by pistons.‌[Bedrock Edition only] Water and lava flow around daylight detectors without affecting them.

Placement
To place a daylight detector, use the "Use Item/Place Block" control.
A daylight detector can be "inverted", which reverses the power levels produced by the daylight detector. To invert a daylight detector, aim at the placed daylight detector and use the "Use Item/Place Block" control.
Activation
A daylight detector activates when exposed to sufficient daylight (daylight detector mode) or when exposure to daylight is low enough (inverted daylight detector mode).
Sources of block light (torches, glowstone, etc.) cannot activate a daylight detector.
Behavior
An active daylight detector:
A daylight detector has no effect on other adjacent blocks (for example, it cannot power a block the way a repeater can).
The output signal of daylight detectors in the loaded chunk is updated every 20 gametime‌[JE only]/daytime‌[BE only]. Block update have no effect on daylight detectors.

Daylight Detector

The daylight detector power level depends on the time of day, the weather, and the internal sky light level.

Inverted Daylight Detector

Using a daylight detector inverts it. However, the output of the inverted detector is not a simple inversion of the daylight detector's output; it uses a much simpler algorithm that depends only on the internal sky light level. Specifically, it outputs a signal strength of 15 minus the current internal sky light level, where values over 15 or below 0 are taken as 15 or 0 respectively. This means that an inverted daylight detector actually outputs a strength of 11 at midnight when it's clear weather, if it has line of sight with the sky. The effects of shade are applied before inverting, so shade increases the signal strength when it isn't already full, and prevents it from reaching zero.

Fuel

Daylight detectors can be used as a fuel in furnaces, smelting 1.5 items per block.

Note Blocks

Daylight detectors can be placed under note blocks to produce "bass" sounds.

Block data

A daylight detector has a block entity associated with it which stores only its entity ID and position (the minimum data for a block entity). Although the daylight detector's block entity stores no additional data, the block entity ensures that the daylight detector is updated every game tick.

Java Edition:

  • Block entity data
    • Tags common to all block entities

Bedrock Edition:

See Bedrock Edition level format/Block entity format.

July 6, 2010Notch suggests that he may implement daylight sensors (in the blog post mentioning Alpha 1.0.2_01).
November 24, 2012Jeb stated that there may be a daylight sensor.
January 2, 2013Jeb tweeted an image of the daylight sensor.
