Soil Hygrometer Humidity Detection Module Moisture Sensor For Arduino

This is a simple water sensor, can be used to detect soil moisture

Module Output is high level when the soil moisture deficit,or output is low

Can be used in module plant waterer device, and the plants in your garden no need people to manage

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

Interface Description(4-wire):

VCC: 3.3V-5V

GND: GND

DO: digital output interface(0 and 1)

AO: analog output interface

Instructions for Use:

Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil

Module to reach the threshold value is set in the soil moisture, DO port output high, when the the soil humidity exceeds a set threshold value, the module D0 output low

The digital output D0 can be connected directly with the microcontroller to detect high and low by the microcontroller to detect soil moisture

The digital outputs DO shop relay module can directly drive the buzzer module, which can form a soil moisture alarm equipment

Analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture
