Automatic watering control system

The invention relates to an automatic watering control system. The automatic watering control system comprises a flower body and a plantation container. The lower portion of the flower body is provided with an annular water-dripping pipe supported by four support legs. A temperature and humidity sensor is inserted in soil in order to collect temperature and humidity values of soil. Then, collected data is sent to a single chip microcomputer having an A/D and D/A conversion function. Proper temperature value T0 and proper humidity value S0 of a flower are stored in the single chip microcomputer. The single chip microcomputer is used for correcting proper humidity value S0 according to temperature deviation Delta T equal to T1 minus T0. Correction S Delta is equal to S0 plus Delta T/T0*S0. Then, the single chip microcomputer makes a comparison between soil humidity value S1 and corrected S Delta in order to control the working state of an electromagnetic valve. A pressurized water tank is used for watering the plant by means of the annular water-dripping pipe.The automatic watering control system has following beneficial effects: the automatic flower pouring control function is fulfilled in order to provide good technical support for living and an office environment of people.
