Soil Moisture Sensor Module For Arduino & Other

Soil Moisture Sensor Module For Arduino & Other

Soil Moisture Sensor Specifications:-
Operating voltage: 3.3V~5V
Dual output mode, analog output more accurate
A fixed bolt hole for easy installation
With power indicator (red) and digital switching output indicator (green)
Having LM393 comparator chip, stable
Panel PCB Dimension: Approx.3cm x 1.5cm
Soil Probe Dimension: Approx. 6cm x 3cm
Cable Length: Approx.21cm
VCC: 3.3V-5V
GND: GND
DO: digital output interface(0 and 1)
AO: analog output interface

Connections:-
VCC connect to 3.3V-5V
GND connect to GND
DO digital value output connector（0 or 1）
AO analog value output connector

Usage:-
Soil moisture module is most sensitive to the ambient, generally used to detect the moisture content of the soil.
When the module can not reach the threshold value, DO port output high, when the the soil humidity exceeds a set threshold value, the module D0 output low;
The small board digital output D0 can be connected directly to the MCU, MCU to detect high and low, to detect soil moisture;
Small board digital output DO can directly drive the buzzer module or relay module in our store, which can form a soil moisture alarm equipment;
Small board analog output AO and AD module connected through the AD converter, you can get more precise values ​​of soil moisture;
