Sensor-Moisture

The product number of Sensor-Moisture is: MSDT23 Sensor-Moisture is a soil humidity detection sensor.

Introduction of Sensor Pins

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.

Development

microduino-Moisture can be applied in soil humidity detection of the potted plant, agricultural irrigation and soil erosion.

Application

• All hardware needed: Microduino-Core, Microduino-USBTTL, Microduino-Sensorhub, a USB cable and wires;
• Software:　　
  • Make sure you build Microduino IDE. If not, please refer to: Microduino Getting start
• Stack all modules and connect the Moisture module to A0 port of Sensorhub with a wire.
• Open Arduino IDE, select File→Examples→Basics→ReadAnalogVoltage program examples, choose the right board from Tools→Board and then compile.
• Select the right port from Tools→Serial Port in Arduino IDE after compiling, then download program.
• After download, you can open the serial monitor and tell soil humidity from the displayed value, which is "0.00" when the Moisture sensor doesn't touch any object and will become bigger than 0" when touching the soil.
