Arduino Soil Moisture Sensor

This video tutorial explains how to use a resistive soil moisture sensor with an Arduino. It covers the sensor's functionality, wiring, and coding using Tinkercad. The tutorial also discusses powering the sensor intermittently to prevent probe oxidation and using LEDs to indicate soil moisture levels. Calibration and practical applications are highlighted for effective sensor use.

What is the primary function of a resistive soil moisture sensor?

Explain how the resistance between the probes of a soil moisture sensor changes with soil moisture levels.

Describe the wiring connections needed to set up a soil moisture sensor with an Arduino.

What is the purpose of using a digital pin to power the soil moisture sensor intermittently?

How can you use the readings from the soil moisture sensor to control LEDs?

Discuss the importance of the threshold value in the context of soil moisture monitoring.

What steps are necessary to calibrate a physical soil moisture sensor?
