Door handle state detection device and method

The invention discloses a door handle state detection device, which is arranged in a door handle, and comprises a setting module used for presetting the angle of the door handle in an open state and the angle of the door handle in a closed state; an acquisition module, used for acquiring the current angle of the door handle in real time; a processor, used for comparing the current angle with the angle of the opening state and the angle of the closing state, if the current angle is consistent with the angle of the opening state, the current state of the door handle being judged to be the opening state, and if the current angle is consistent with the angle of the closing state, the current state of the door handle being judged to be the closing state; a communication module, used for sending the current state of the door handle to the gateway. By installing the detection device in the door handle, the opening and closing state of a door or a window in an intelligent home system can be monitored at low cost. 本发明
