The modification MoreObservers adds 4 new observer blocks to the game.
Mobserver - can detect all living creatures in a 5*5*5 area in front of it and also detects through solid walls.
Surveyor - measures the distance to the first block in the direction it is facing. The redstone signal decreases as the distance increases.
Toggle Observer - works like the vanilla observer, but it changes the signal strength between 15 and 0. After changing, it ignores further actions for 25 ticks.
Discerner - checks the block's stage and gives a signal (for example, the growth stage on a farm).
