Abstract: An irrigation system that controls the irrigation operations based upon soil irrigation decisions and weather forecasts generated by specific meteorological data, including soil temperature, soil moisture, air temperature, air humidity, air pressure, and rainfall collected by different sensors. The system comprises an irrigation decision module, a soil decision module, an air factor decision module, a rainfall information sensor, an irrigation controller, and a mobile APP. The irrigation system uses low-power radio frequency networking technology to communicate between different modules and devices.
Abstract: The present invention provides a method and a device for iris recognition. By providing a sensing unit under the iris recognition region of the display unit, the invention can capture the iris information of the user's eyeball in time, and then compare with the presetting iris information, and execute the operation instruction corresponding to the iris information, thereby effectively improving the precision of the iris recognition. In addition, the sensing unit is disposed under the display unit, and the overall thickness of the mobile device can be effectively reduced compared with the structure in which the camera is protruded and disposed independently outside the region of the display screen, so that the wearable device or the mobile device is thinner and more suitable for flexible wearable devices or mobile devices, to meet the needs of the market.
