Daylight sensors will work when placed even in the deepest caves as long as at least some natural light is getting through to them, even if it’s not coming from directly above them. Note this means you cannot over-power a sensor using, say, a glowstone block.

Daylight sensors produce an output proportional to the current natural light level.If there are 91 entities on the plate, the signal strength is 10. Iron pressure plates increase the signal strength by 1 every 10 entities.If there are 5 entities on the plate, the signal strength is 5. Gold pressure plates increase the signal strength by 1 every 1 entities.Note that stacks (such as 64 cobblestone) and the player count as one single entity. Weighted pressure plates produce an output proportional to the number of entities currently on that pressure plate (note even player entities count as just one entity).If two players have it open on their screen, the signal strength is 2. Trapped chests produce an output proportional to the number of players simultaneously accessing that chest.These sources do not use a redstone comparator, but are still capable of varying signal strength. Non-comparator-based, of which there are only four.Again, we want to consider two types, but this time the distinction is even simpler: Variable power sources, as the name indicates, output a signal strength which changes or varies according to their input. The advantage of this is you can create arbitrarily separated redstone pulses by placing detector rails at arbitrary intervals. Detector rails produce a short pulse when a minecart passes over them, or constant output if the minecart remains on them.The signal is taken from the blocks to which the tripwire hooks are attached. The signal turns off immediately when the entity’s hitbox exists the string’s hitbox. Tripwire hooks connected with a piece of string will trigger and produce a constant output while an entity falls through or steps on said string.Similarly to buttons, the signal remains for longer using a wooden pressure plate over a stone one.



Power sources which are off by default.Their main advantages are the fact that they act just as a normal block and as thus can be moved by pistons, in addition to being placeable on ceilings. Redstone blocks are created by combining 9 redstone dust on a crafting table.If they are placed directly below a block, they will strongly power that block, but if they are placed on it the block will be unaffected. They are the basis of all logic gates in Minecraft and they can be placed on the sides or top of a block, but not on the bottom. Redstone torches are created with a stick and redstone dust.There are just two components in this group: You cannot turn them off in any way and you must destroy them or move them to unpower wires near them. They will also strongly power any block they are connected to, with the exception of the redstone torch (see below). They will power any redstone wire adjacent to them with signal strength 15, the maximum possible. Fixed power sources always output the same exact signal strength.
