For anybody looking at this video an easier way to do the sensor is to have the blocks above the watering system and having the sensor point upwards so you don't have to upgrade it.
Thanks man, I was able to recreate this. It's a game changer from manual farming. Do you have any ideas to disable the sensor on the return trip? It uses 2x as much water as it needs to right now.
Great job keep doing scrab mechanic survival '..... Just that you should have shown us the working machine not just the tutorel part .....any nice job...👍🏻
