Wireless Sensing Circuit Design
Sensing signal input
Control relay signal output
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.

ConclusionsThis system can economize on water, and it can observe quantity of water in every season. The best advantage can reduce consumption of human resources. So, this paper emphasis on making green by planting trees, saving of time and labour and saving energy.
