12V Relay Soil Moisture Sensor

12V Relay Soil Moisture Sensor Controller Module Lower Humidity Start Automatic Watering

Product Description:
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.

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.

Package Including:
1 Soil Humidity Sensor
1 Relay Control Module
