Soil Moisture Sensor Module

Digital and analog output Soil Moisture sensor Module

This is a simple Soil Moisture water sensor, can be used to detect soil moisture Module Output is high level when the soil moisture deficit, or output is low.  It can be used in module plant water device, and the plants in your garden no need people to manage.

• Operating voltage : 3.3 to 5 Volts.

• Dual output as well as analog output.

• Red LED for Power Indicator.

• Green LED for Digital output indicator

• LM393 comparator used.

Interface Description(4-wire):

• VCC : 3.3 - 5 Volts 
  
• GND : GND
  
• DO : digital output interface(0 and 1)
  
• AO : analog output interface

We have Various sizes of Sensor Modules. Check out our complete collection of Sensor Modules

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.
