For example, the humidity standard includes a lower humidity limit and an upper humidity limit, and if the acquired soil humidity is lower than the lower humidity limit, the irrigation is started, and if the acquired soil humidity is higher than the upper humidity limit, the irrigation is stopped. The drip irrigation unit automatically monitors the soil humidity based on the humidity sensor, drip irrigation is carried out when the humidity is lower than a set value, alarm reminding can be preferably carried out, and irrigation is stopped when the humidity rises to a normal level. It should be noted that, it belongs to the prior art to compare the humidity obtained by the sensor with the humidity standard prestored to control whether the switch is turned on, and this application does not relate to the improvement in the method. When the water in the water storage device of the irrigation unit comes from a condensation water taking unit, air is blown into the device by a first fan when the condensation water taking unit works, the air introduced into a semiconductor condenser is pre-cooled by a waste heat recovery and exchange device, an outlet of the waste heat recovery and exchange device is connected to a cooling space surrounded by semiconductor refrigeration sheets in a semiconductor refrigerator, and when the temperature of the air is reduced to be close to the dew point temperature, condensed water is separated out from the surfaces of the semiconductor refrigeration sheets and is collected by a water condensation chamber; and meanwhile, dry cold air after condensate water is separated out enters the tail air channel, heat exchange is carried out again when the dry cold air passes through the waste heat recovery and exchange device, carried cold energy is transferred to newly introduced external environment air in a heat conduction mode, and finally the dry cold air is introduced into an exhaust port through a second fan and exhausted to the external environment, and meanwhile, heat dissipation is carried out on the semiconductor heating end. In addition, air temperature information can be acquired through a temperature sensor at a condensation air duct of the semiconductor condenser, and when the air temperature is reduced to zero, the condensation water taking unit is automatically started. When setting up solar panel and battery simultaneously, solar panel can be stored solar energy transformation for the electric energy when the intensity of sunshine is enough in the battery, and the dc-to-ac converter is used for protecting supply circuit. For example, the conversion rate of solar photovoltaic power generation is about eleven percent, and about 14W of power is supplied per square meter under sunny days, so that most of energy can be supplied for the system to work.
In conclusion, the drip irrigation unit controls whether to continue irrigation or not based on the humidity sensor, and when the humidity is insufficient, the drip irrigation water supply branch is opened for drip irrigation; when the humidity is in the proper range, the drip irrigation water supply branch is closed to stop drip irrigation.
