| Research Abstract |
Wireless modems were used and the usage methods were investigated in order to data transmission. Collected data by meteorological observation instruments were tried to transmit from computer A to computer B through wireless modems.
In conclusion, data transmission by wireless modem is a possible method. But, because power supplies are necessary for computer operation in both side's, wireless modems have some limitations for the investigations in the field where power supply is not useful. Data transmission by wireless modem is convenient in cases both sites can use power supply, but cannot connect on lines between them. Environments related to crop cultivations was investigate from a view point of water stress. It is concluded that the growth of roots is influenced by soil moisture, and the water stress are appeared on water potential in crops and leaf temperature in close relation to conditions of atmosphere in SPAC model.
