Description

This is an easy to use digital
soil moisture sensor. Just insert the sensor in the soil and it can can
measure moisture or water level content in it. It gives a digital output
of 5V when moisture level is high and 0V when the moisture level is low
in the soil. 

The
sensor includes a potentiometer to set the desired moisture threshold.
When the sensor measures more moisture than the set threshold, the
digital output goes high and an LED indicates the output. When the
moisture in the soil is less thatn the set threshold, the output remains
low. The digital output can be connected to a micro controller to sense
the moisture level. The sensor also outputs an analog output which can
be connected to the ADC of a micro controller to get the exact moisture
level in the soild.

This sensor is great for making water gardening projects, water sensing, etc.

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;
