Description: 1. Ideal for effectively monitoring soil moisture and automatically watering your plants and flowers. 2. This capacitive sensor, placed in the soil around your plants, uses a second sensor and a mainboard to detect if the soil needs more water to replenish moisture and if its dehydrated. When your soil is too dry, a pump activates, and water flows into the tube and vase.
