E. ) that makes the water pump like this came out is through irrigation conduit, and the irrigation is in charge of, at last from the shower nozzle spout to the field everywhere, realized the purpose of irrigating. Wherein controlling means adjusts the water yield of irrigating through controlling the control flap on each irrigation conduit. Wherein soil moisture content detection device's soil moisture content detects the soil moisture content that soil can be gathered to the sensor to converting it to electric signal transfer and giving processing circuit, send the single chip circuit to after processing circuit handles, the single chip circuit is recycled the output data line and is sent controlling means to, and under the effect of PID regulator, irrigation water quantity is adjusted to controller adjustment control flap's aperture, realizes accurate the irrigation.
