“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.

Capacitive Moisture Sensor
Storage Containers (Not the same, but should work)
I’ve used the MicroBit version 2, but this project can be made using the first version as well.”
