Do you tend to forget to water your plants? Overwater them? The cool new Thirsty Light is a digital plant moisture sensor that alerts you with a blinking LED light when your plant is thirsty and needs water. It has a Drypoint digital circuit that continuosly monitors conditions and tests the moisture level in the soil once per second. It's simple to use too, because it has no gauges or complicated readouts, just a blinking light telling you to add water.
I hope in a future version, it could whisper out warnings like, "Psst, I know you could care less about ferns like me, but could I possibly get some water? I'm dying -- crumbling into dust -- HELP ME!!!!"
