4. Sensor (a) Sensor(b) NPN ON

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

6. Labview Interface Design Front panelFunction 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.

7. Labview Interface Design Front panelFunction 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.

15. Conclusions This 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.
