• Why is soil moisture essential?

  It is essential for plant growth and agriculture
• Where does soil moisture come from?

  Precipitation, irrigation, groundwater movement
• What is the effect of overwatering on succulents?

  They may suffer from root rot
• What should you consider before growing plants?

  Time and care needed for plants
• What is a soil moisture sensor?

  An electronic device measuring soil water content
• How does a soil moisture sensor help plants?

  It optimizes water usage for growth
• What part of the sensor contacts the soil?

  The probe
• How does the probe detect moisture?

  By measuring electrical resistance
• What does higher resistance in dry soil indicate?

  Higher resistance means drier soil
