Hey everyone.

This project helps you to connect the soil moisture sensor to Arduino and shows how it works. Check out this link for learning:

Plant Health: Basic Soil Moisture Sensing

The Soil Moisture Sensor (Resistive type) is a simple but effective way to start with plant automation. It allows you to monitor the health of your indoor garden by measuring how easily electricity flows through the soil.

Interaction Logic

The project uses a simple probe that you insert into the soil:

  1. The Signal: Dry soil has high resistance, while wet soil conducts electricity better.
  2. The Goal: The Arduino converts this into an analog reading (0 to 1023).
  3. Thresholds: You can set an "Alert" value—for example, if the reading drops below 300, a red LED flashes to tell you the plant is thirsty.

Components List

  • Arduino Uno/Nano: The logic brain.
  • Resistive Soil Moisture Sensor Module: The primary hardware.
  • LEDs (Red/Green): To show "Thirsty" vs "Saturated" states.
  • Piezo Buzzer (Optional): For an audio reminder to water your plants.

Maintenance Tip

Note that because this sensor is "resistive," electricity flowing through the probes causes electrolysis, which leads to corrosion over time. To make your sensor last longer, only power it up when you are actually taking a measurement (once an hour) rather than leaving it on constantly.
