Light meters are extremely useful tools in photography. Essentially, light meters help photographers capture the perfect image tone. These light measuring devices help photographers know if part of an image is overexposed or underexposed.

Thermal anemometers, or hot wire flow sensors, measure the flow rate by monitoring the amount of heat removed from a surface using one or more simple temperature sensors. They have found wide use in the automotive industry for monitoring the air intake of the engine.
