Description:


  1. Using the company's high-quality soil sensors do detect soil moisture , the surface of nickel plated , has widened the induction area can improve conductivity, prevent contact with the soil rust problems and prolong life ;
  2. When two products can be a wide range of soil moisture control , regulation and control by potentiometer corresponding threshold , the humidity is below the set value , DO output high , higher than the set value , DO output low ;
  3. Using LM393 comparator chip , stable
  4. Operating Voltage 3.3V-5V

       5.  Has a fixed bolt holes for easy installation

       6.  PCB Size : 3.2cm * 1.4m

Wiring instructions: ( 4 -wire )

1. VCC external 3.3V-5V

2. GND GND External

3. DO small board digital output interfaces ( 0 and 1 )

4. AO analog output voltage of small plates

 

Module for use:

1 sensor for detecting moisture in the soil ;

2 module is the blue potentiometer to adjust the threshold for soil moisture , clockwise adjustment, control humidity will be bigger, smaller counter-clockwise ;

3 digital outputs D0 can be directly connected with the microcontroller through the microcontroller to detect high and low , thereby detecting soil moisture ;

4 small plates AO analog output modules can be connected and AD through the AD converter , you can get a more accurate value of soil moisture ;

 

Packing list:

1*Soil sensor module and a set

1* DuPont line
