Soil Moisture Meter Detection Module for Arduino Gardening

Hi guys,

Have Created program to detected soil sensor using arduino which helps to determine the condition of the soil before planting and while watering the plants.

Hope you are been helped with this instructable.

cheers

Step 1: Using Arduino Uno

Connecting the arduino with the soil sensor

Step 2: Material Requirements for Soil Sensor With Arduino

1) Arduino uno

2) Soil sensor http://www.amazon.in/gp/product/B00AYCNEKW?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00

3)LM393 comparator chip

4) 2 Female jumper

5) 3 Male-Female Jumper

Step 3: Circuit Diagram

Step 4: Code and Out Analysis

Output Result analysis:

Output

• Sensor in air:

value = 0

sensor = 0

sensor = 0

sensor = 0

sensor = 0

• Sensor in dry soil:

0 < value < 300

sensor = 35

sensor = 41

sensor = 38

sensor = 49

• Sensor in humid soil:

300 < value < 700

sensor = 578

sensor = 576

sensor = 582

sensor = 589

• Sensor in water:

value > 700

sensor = 934

sensor = 940

sensor = 938

sensor = 940
