Crash Course: Using the Soil Moisture Sensor

Objective

Teach learners how to use the soil moisture sensor to measure soil moisture, and integrate its readings with a TRIOE microcontroller.

Materials Required

  • Soil Moisture Sensor Module
  • TRIOE
  • Breadboard and jumper wires
  • USB cable for programming the TRIOE
  • Computer with Arduino IDE installed

Steps

1Understand the Soil Moisture Sensor

  • The soil moisture sensor measures the moisture content of soil.
  • Pin Description: VCC: Power supply (3.3V or 5V), GND: Ground, AO: Analog output signal.

2Set Up the Circuit

  • Connect the VCC pin to the TRIOE's 5V.
  • Connect the GND pin to the TRIOE's GND.
  • Connect the AO pin to the TRIOE's analog pin A0.

3Install the Moisture Sensor Library

  • Open the Arduino IDE.
  • Go to Sketch > Include Library > Manage Libraries.
  • Search for 'MoistureSensor' and install the library.
  • Also, install the 'MoistureSensor' library, if prompted.
