Soil Hygrometer Humidity Detection Module Moisture Water Sensor Soil moisture for Automatic Watering Device 12V
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;
