Feature: 1. The module has a screen, which is convenient for the operator to watch the specific figures of soil moisture and make judgments. 2. The module has different operations when the soil moisture is different. When the soil moisture is lower than the set value, the pump starts watering, and when the soil moisture reaches the set value, it stops watering, so the operation is very simple. 3. The module has superior sensing performance and very good performance. 4. This module has a built‑in high‑quality relay, which can control the on/off of the watering system according to the set start/stop watering value. 5. The probe of this module can be directly inserted into the soil to get an understanding of soil moisture.
