This mod added four observer.
Mobserver, which detects all mobs and players in the 5x5x5 region in front of it. It can detect through solid walls.
Surveyor, which measures the distance to the first block in the direction it's looking. It outputs 15 if there's a block right in front of it, and the value drops as the distance increases.
Toggle Observer, crafted with an observer and a lever. This functions the same as a normal observer, but instead of outputting a 2-tick pulse, it toggles signal strength between 15 and 0. After it flips, it ignores further block changes for the next 25 ticks. So for example, if you wire up a stone button to the front, the output at the back will be as if you were toggling a lever instead of pressing a button. (You can build this in vanilla, but it's far more complicated and expensive than it needs to be.)
Discerner currently does the same thing as a comparator for single blocks' states, but supports a few extra integer properties. In a future version I'll change vanilla comparators to also work for those additional blocks, and then change this block to do something else.
