Soil Moisture Sensor/ Soil Hygrometer

Soil Moisture Sensor/ Soil Hygrometer

Description:

  • 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
  • Adjustable sensitivity by adjusting the digital potentiometer (shown in blue)
  • Operating voltage:3.3V~5V

  • Adjustable sensitivity by adjusting the digital potentiometer (shown in blue)
  • Operating voltage:3.3V~5V
  • Dual output mode, analog output more accurate
  • A fixed bolt hole for easy installation
  • Panel PCB Dimension: 3cm x 1.6cm
  • Soil Probe Dimension: 6cm x 2cm
  • With power indicator (red) and digital switching output indicator (green)
  • Having LM393 comparator chip, stable

    Interface Description (4-wire)
  • 1. VCC: .3 V-5V
  • 2. GND: GND
  • 3. DO: digital output interface (0 and 1)
  • 4. AO: Analog Output Interface

    Instructions for use
  • 1. Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil
  • 2. 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
  • 3. The digital output D0 can be connected directly with the microcontroller to detect high and low by the microcontroller to detect soil moisture
  • 4. The digital outputs DO shop relay module can directly drive the buzzer module, which can form a soil moisture alarm equipment
  • 5. Analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture
