This smart hygrometer consists of two parts - white and black. The black part is stuck into the coconut substrate and the white part serves to signal the condition of the soil. The white part is not intended for direct contact with water, so pay attention to this when watering. The signal diode in the white part has three active states, thanks to which you will know how your plant is doing with humidity.

​

• Blue - shows that the plant is sufficiently watered and the soil has high moisture. (61% - 100%)

• Green - means medium humidity of the substrate, the plant is fine (16% - 60%)

• Red - low soil moisture and the plant should be watered as soon as possible. (0% - 15%)
