In sensor categories, which option refers to monitoring electrical energy or supply for the system?

Explanation:
Power sensors focus on the electrical energy or supply feeding the system, such as voltage, current, battery level, or overall power availability. This helps ensure the controller and field devices have a reliable energy source and can alert you to under- or over-voltage conditions that could affect operation or cause failure. The other options describe different sensing aims: Location is about where a device or asset is, Humidity measures moisture levels in air or soil, and Flow assesses how much water is moving through a line. So monitoring electrical energy or supply falls under Power.
