ITEM NAME:12V Soil Moisture Monitoring Module and Automatic Watering Device #JT1 Product Description Description: Descriptions: When soil moisture is below the set humidity, the relay will automatically pull start the spray, pump, do humidifying action. It will stop automatically when it reaches the set humidity. Applications: By adjusting the soil moisture threshold value on the potentiometer, you can automatically water your vegetable farm and garden, and control soil moisture in your flowerpots. The large power relay enables you to control large current equipment. When the humidity is below the set value, the relay starts; when the humidity is higher than the set value, the relay shuts down. The delay function can solve the problem that when in no delay moisture critical state, the relay keeps flickering. It is easy and practical to use. Features: 1. This high-quality nickel plated soil moisture sensor is used to detect soil moisture. Its widened sensing area can improve conductivity, prevent rust easily contact with soil problems and prolong life; 2. It can be used to control soil moisture over a wide range by adjusting the corresponding threshold value on the potentiometer. When the humidity is below the set value, the relay starts; when the humidity is higher than the set value, the relay shuts down; 3. It has a delay function with 3-5 seconds delay. When the humidity in the critical.When the humidity is below the set value, the relay starts; when the humidity is higher than the set value, the relay shuts down. It is easy and practical to use. It will stop automatically when it reaches the set humidity.
