The moisture sensor for micro:bit allows your micro:bit to detect moisture, so if your plant is thirsty you'll know about it! or how about using one and a couple of micro:bits to tell you when your bath has reached the correct level?

To hook this up to your micro bit you will require alligator cables alternatively you can solder headers or a screw terminal to the board to make hooking it up to your other micro controller projects a dream.
