DC 12V Relay Controller Soil Moisture Humidity Sensor Module Automatically Watering

Specifications:
Supply voltage:12VDC
Input current:more than 100ma
Load:250V 10A AC or DC 30V 10A (below a current of this range can be used)
Humidity is below the set humidity start means that when soil moisture is below the set humidity,the relay will automatically pull, start spraying,water pumps,etc.do humidifying action reaches the set humidity is automatically stopped.
Purpose:
Adjustable via potentiometer control soil moisture threshold,which can automatically vegetable garden,garden automatic watering,household pots of soil moisture control,electronic game,etc.,with a power relay,can control high current devices, less than the set humidity automatically start relay , more than the set humidity automatically disconnected,and a delay function to resolve without delay the humidity critical state relay flickered question is a simple and practical soil moisture control system.

Module for use:
1 soil moisture sensor for detection
2 module blue potentiometer is used to adjust the soil moisture threshold,clockwise adjustment, control humidity greater counterclockwise smaller
3 with a delay due to the module functions in the regulation of humidity values,each tune a need to wait for 5-8 seconds or so to see changes in the relay,the green LED lights also have the corresponding changes until transferred to meet the requirement.
Size:5x2.1cm/1.97x0.83inch
