Indoor Water Sensors

 A water sensor is a very handy device for those of us who keep forgetting to water our houseplants.  When the water in the soil is low, the sensor will alert you with a light or a sound.  They can mean the difference between having beautiful houseplants or having a dead houseplant. 

Fertile Earth WaterStik Plant Moisture Sensor

by Fertile Earth

  • By using the WaterStik InstaRead button the user can simply push the button and know immediately the status of the plant
  • The Waterstik identifies when the plant has been over watered
  • Color of light indicates if the plant needs water or not
  • Blue means overwatered Green mean good Yellow means water soon and Red means water now
  • Depth gauge allows you to adapt the WaterStik to different plant types and watering habits

The WaterStik is a revolutionary moisture sensor designed to automatically remind you when to water your indoor plants. The multi-colored LED instantly tells you the status of your plant. The WaterStik not only reminds you when to water, but it also tells you if you've overwatered. The WaterStik is the only indoor moisture sensor that measures the actual variance between the soil and the water, thus is not susceptible to variations in the soil. The depth gauge tells you how deeply into the soil to place the stick. These were determined by analyzing the moisture demands of specific plant types. The WaterStik runs on two 1-1/2 volt button cell batteries, which last approximately one year. The color of the light indicates if the plant needs water or not. Blue indicates too wet, green indicates good moisture level, yellow notifies you to water soon and red warns you to water now. The WaterStik works in 4 inch to 10 inch planters. Sensor will flash red when the plant is in need of water. You can also test the moisture level at any time in any potted plant by pressing the button for an instant reading.

Hydrofarm HGTL Thirsty Light Original Digital Indoor Plant Moisture Sensor

by Hydrofarm

  • LED light alerts user when plant needs water
  • Corrosion resistant brass probe
  • 2 Replaceable 1/5v batteries
  • ABS plastic casing
  • Perfect for forgetful plant waterers

The Thirsty Light is a 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. Thirsty Light 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. When it reaches the fifth level, "completely dry", the device goes into 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.
