Arduino Soil Moisture Sensor
Arduino soil moisture sensors are used to measure the moisture levels of plants or soil. They are commonly used to determine the watering needs of plants or for automatic irrigation systems. Here are some general facts about soil moisture sensors:
- Working Principle:
- Soil moisture sensors measure the electrical conductivity of water in the soil to determine the moisture level. Higher moisture levels result in higher conductivity.
- Structure:
- A soil moisture sensor typically consists of two or more electrodes buried in the soil. These electrodes measure the conductivity between them.
In this project, we will use a moisture sensor that produces analog signals. We will divide these analog values into specific intervals to monitor the soil moisture. Based on the moisture level, 3 LEDs will light up sequentially, providing us with information about the soil’s moisture content.
