The utility model discloses an automatic door control circuit with low cost. The system comprises a main control module, the main control module is provided with an analog-to-digital converter and a pulse width modulator; the main control module is connected with a detection module; the main control module is provided with a direct-current motor driving module; the direct-current motor driving module is connected with a direct-current motor; the main control module provides pulse voltage for the detection module; the detection module transmits a microwave signal; a microwave signal reflected by the object is received; the emitted microwave signal is inconsistent with the microwave signal reflected by the object; the output voltage of the detection module is changed; the output voltage is converted into a digital signal through an analog-to-digital converter; whether an object moves or not is judged according to the size of the digital signal, if yes, the main control module sends out pulse electricity with a
