When your plant is thirsty, the soil moisture sensor will show you by a blinking red light
It is always difficult to determine whether a houseplant is getting enough, too much or not enough water. This water meter is an excellent help! A sensor in the probe of the water meter indicates whether the soil is moist or not. When the red color blinks the soil is completely dry and with a green color it is still moist. When the soil is getting less moist, it turns orange.
Both instant and permanent mode. We recommend to use the Plant Thirsty Light indoors. Two LR44 batteries are included. They last about 1 year and are easy to replace. English manual.

The Plant Thirsty Light comes packaged in “off” mode to preserve battery life. Before inserting the item into the soil turn it “on” by pressing and holding the button for 3 seconds. Upon activation the item will blink 3 times and will immediately start to measure water content.
Insert the item into the soil of your plant. Make certain that the soil is gently compacted around the probe with your fingers. Push the soil moisture sensor into the soil until it reaches “5” on the probe. Once the item is turned on, it will test soil moisture every two hours. If the moisture level is normal, the indicator will blink green once. When the plant needs water the indicator will blink orange 3 times. The moment the indicator will blink red every six seconds it reminds you to water immediately. While adding water, the moisture level will go back to normal and the indicator will stop blinking red. It will soon blink green once, to indicate the moisture level is sufficient again. Easy to adapt if you want the sensor to warn you earlier or later dependent on how much water your plant needs (see the manual).
