Soilbot

a UTRAHacks 2023 hackathon project: a soil moisture sensor that tracks a plant's watering status.

the whole thing runs on an arduino. a moisture probe sits in the soil and the arduino reads how wet it is, then turns that reading into a simple watering status so you know at a glance whether the plant needs water.

an LCD on the front gives the live readout, so instead of guessing or poking the dirt with a finger you just look at the screen.
