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 ;

Package Included:
