    Disclaimer:

    1 This is a summary of the moisture sensor can be used to detect the moisture of the soil, when the soil is dry , the module outputs a high level , whereas the output low. Using this sensor make an automatic watering system , so that your garden plants need people to manage .

    2 adjustable sensitivity ( shown in blue digital potentiometer adjustment )

    4 Operating Voltage 3.3V-5V

    5 Module Dual Output mode , a simple digital output , analog output more accurate.

    6 with fixed bolt hole for easy installation

    7 small PCB board size : 3cm * 1.6cm

    8 power indicator ( red ) and the digital switch output indicator ( green )

    9 using LM393 comparator chip , stable

    • VCC external 3.3V-5V
    • GND GND External
    • DO small board digital output interfaces ( 0 and 1 )
    • AO small board analog output interface

    Instructions

    • A soil moisture and humidity module most sensitive to the environment , usually used to detect soil moisture .
    • Modules in the soil moisture reach the set threshold , DO port output high when soil moisture exceeds a set threshold, the module D0 output low ;
    • Digital outputs D0 small plates can be directly connected with the microcontroller through the microcontroller to detect high and low , thereby detecting soil moisture ;
    • Small plates digital output DO OUR relay module can directly drive the buzzer module , which can be composed of a soil moisture alarm equipment ;
    • 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 ;
