Thirsty Light Original

The Thirsty Light is an intuitive digital plant moisture sensor that blinks an LED to alert the user when it is time to water a potted plant. It is designed to be unobtrusive when left in the soil of a plant, where it continuously monitors conditions, testing the moisture level once per second.

The circuit that drives the device, called Drypoint, can sense 5 different levels of dryness, causing the light to blink faster as the soil gets dryer, increasing the urgency of its call to action, until it reaches the fifth level, “completely dry”, which puts the device in standby mode to conserve electricity, emitting a double blink every 3 seconds. There is a low-battery mode as well: a slow triple blink. The Thirsty Light comes with a comprehensive and informative user and watering guide, and is backed by a 30 day manufacturer’s warranty.
