  • In this activity, students construct a simple, effective moisture sensor that is then used to give warning of dry, damp or wet conditions.

    By the end of this activity, students should be able to:

    • construct a simple moisture sensor
    • conduct a series of experiments to investigate how various moisture sensors work.
