FC-28-D Soil Hygrometer Detection Module + Soil Moisture Sensor

Detect and/or monitor soil moisture level. Using this sensor and ARDUINO or similar microcontroller you can make an automatic device to monitor plants moisture level and water plants as needed. You can wire this module’s output as digital or analog. In a digital mode where the output is low bellow preset threshold, sensitivity (threshold) can be adjusted using an onboard adjustable potentiometer. Onboard  LM393 chip does the work. In analog mode, you read moisture probe via Arduino analog input pin.

  • Dual output mode, analog and digital.
  • A fixed bolt hole for easy installation.
  • Having LM393 comparator chip, stable.
  • Panel PCB Dimension: 3cm x 1.5cm.
  • Soil Probe Dimension: 6cm x 3cm.
  • Cable Length: 21cm.
  • Interface Description(4-wire):
  • VCC: 3.3V-5V.
  • GND: GND.
  • DO: digital output interface(0 and 1).
  • AO: analog output interface.

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