  • Pins of the sensor:
    • PIN1: GND
    • PIN2: VCC
    • General signal pins:
      • PIN3(IO1): digital/analog signal
      • PIN4(IO2): NC(null)
    • Special signal pins:
      • If it is IIC: IO1/IO2 are respectively SDA/SCL.
      • If it is soft serial port: IO1/IO2 are respectively tx/rx.
  • Special to Sensor-Moisture sensor pins
    • PIN1: GND
    • PIN2: VCC
    • PIN3(IO1): Analog read
    • PIN4(IO2): NC


Microduino sensor can communicate with core module through the connection with Microduino-Module Sensor Hub.

Result

  • After download, open the serial monitor
  • The return value of the sensor is "0.00" when it doesn't touch anything, and the value will be larger than 0 when it touches the soil. The displayed value respresents the moisture of the soil.

Application

It can be applied to potted plants, agricultural irrigation, soil loss and other soil moisture detecting situations, and it can serve for irrigation control.
