Smart Plant Moisture Sensor

Build a simple sensor to measure soil moisture and learn when plants actually need water! Explore how sensors and data help improve sustainability and reduce water waste.

Materials:

• Soil moisture sensor

• Microcontroller (such as Arduino or similar)

• Jumper wires

• Breadboard

• USB cable or battery pack

• Small plant and soil

Instructions:

1. Connect the soil moisture sensor to the microcontroller using jumper wires.

2. Place the sensor into the soil near your plant.

3. Upload a simple code to read moisture levels from the sensor.

4. Observe the data and identify when the soil is dry or moist.

5. Use the readings to decide when to water your plant.

Try adjusting the sensor position or testing different soil types to see how the readings change.
