“In this Instructable, I’m going to be showing you how to build an automatic plant watering system using a Micro:bit and some other small electronic components.
The Micro:bit uses a moisture sensor to monitor the moisture level in the plant’s soil and then switches on a small pump to water the plant if the soil gets too dry. This way, your plant is always looked after, even when you’ve forgotten about it or you’re away.
