product description:
Product description: 1 using the company s high-quality soil to make the soil moisture sensor detection surface is nickel plated, has widened sensing area can improve conductivity, prevent rust easily contact with soil problems and prolong life;
(2) products can be controlled over a wide range of soil moisture , adjustable via potentiometer control the corresponding threshold , the humidity is below the set value, the relay starts , higher than the set value, the relay is switched off ;
3 product with a delay function , delay 3-5 seconds , when the humidity in the critical condition is detected , the relay does not flicker , flicker occurs;
4 high-quality products using Songle relay can withstand the load of 1500W, meet the requirements of most people;
5 products with a power indicator and relay instructions;
Electrical parameters:
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)
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.
