Development

Program Download

• Download and unzip the programFile:Sensor-Moisture Test.zip

Programming

• Follow the Software Getting Started Guide.
• Select the Board, Processor and Port.
• Click [File]->[Open], browse to the project program address, and click "Sensor-Moisture Test.ino" to open the program.
• After confirming all these items are correct, click "→" to download the program to the development board.

Hardware Setup

• Referring to the following diagram, connect the 将Sensor-Moisture to analog pin A0/A1 of Microduino-Sensorhub.

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.
