Laliva 3D Printer – DC 12V Soil Moisture Sensor Relay Control Module Automatic Watering of The Humidity Starting Switch

Product Details
12V soil moisture sensor controller module Lower humidity start automatic watering
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.
Product Descriptions:
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 modul

5V 2 Channel Relay Module Shield For Arduino ARM PIC AVR DSP 10A

Description : 2-Channel Relay interface board- Just use 5V input signal to control. You can do some simple design about it. This module can be used with Arduino Special Sensor Shield V4.0. Each relay has a normally open- normally closed contact group. It can control various appliances and other equipments with large current. Equiped with high-current relay- AC250V 10A- AC150V 10A-DC30V 10A-DC28V 10A. This is a 2-Channel 5V Relay Module Shield can be controlled directly by a wide range of microcontrollers such as Arduino PIC ARM AVR DSP. Easy to be controlled by a lots of Microcontrollers( Such as Arduino – 8051- AVR- PIC- DSP- ARM- ARM- MSP430- PLC-TTL logic). Specifications : Size: 3.9cm x 5.1cm Materials: PCB board and electronic components Package included : 1 x 5V 2-Channel Relay Module Shield Each relay has a normally open- normally closed contact group.
