A nice block to help you guys automate crops such as sugar canes or anything else you can think of! Simply place a block or item inside the interface of the block detector and it will emit a redstone signal as soon as that block touches any of the sides! Also works with buckets of lava and water to detect water and lava... obviously...

Emits a redstone signal when the block in the interface touches any of the sides. Can be useful for farming and growing stuff!
