This Thirsty Light HGTL is a digital soil moisture monitor that blinks an LED to alert you when it is time to water a potted plant. Designed to be unobtrusive when left in the soil of a plant, it continuously tests the moisture level once per second.
As the soil gets dryer, the light blinks faster. When it reaches the fifth level, completely dry, the Thirsty Light goes into standby mode to conserve electricity, emitting a double blink every three seconds.
