Chirp, a plant watering alarm

Chirp, a plant watering alarm via DP.

It’s a “plant watering alarm” – you set the dry point, then water the plant and then it starts to chirp when the plant dries out. Chirps are rare at the beginning and more frequent when the water level gets really low. It has a LED hooked up as a light sensor, so it does not make noise at night.
