Labview Interface Design Front panel Function

A diagram of curves is showed 0(have water) or 1(have not water).

A pilot lamp is similar to a diagram of curves.It showed green lamp when the pot culture had water ,otherwise it would show red lamp.

Each computer has to choose itself USB com port.

Labview Interface DesignFront panel Function

The table is showed a potted plant's humidity each moment.

The coerced switch will be used when automatic switch  had a breakdown.

The computer's notepade will be recorded one time when the pot culture's humidity had water and had not water.
