12V Soil Moisture Monitoring Module and Automatic Watering Device
12V Soil Moisture Monitoring Module and Automatic Watering Device USD 6.99

12V Soil Moisture Monitoring Module and Automatic Watering Device 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 condition is detected the relay does not flicker. 4. High quality Songle relay can withstand a load of 1500W meeting the requirements of most people;5. It has a power indicator and relay instructions;Electrical parameters:Supply voltage: 12V DC Input current: more than 100mALoad: AC 250V 10A or DC 30V 10A (current below this range is available to use)Module Using Instructions:1. It can be applied in soil moisture detection.2. The blue potentiometer is used to adjust the soil moisture threshold; if adjusted clockwise humidity will become high; if adjusted anticlockwise lower.3. Because of delay in the regulation of humidity values each adjustment needs to wait for 5-8 seconds or so to see changes in the relay and the green LED light also has corresponding changes.
