The system comprises:
the formaldehyde sensor 1 is arranged indoors, the humidity sensor 2 is arranged outdoors, the output ends of the formaldehyde sensor 1 and the humidity sensor 2 are connected with the input end of the controller 3, the output end of the controller 3 is connected with the driving motor of the electric window I4, the electric window I4 is generally arranged in a living room or a bedroom, and the controller is of the type stm32f103c8t 6;
if the formaldehyde sensor 1 detects that the concentration of the indoor formaldehyde is smaller than a first threshold value and the outdoor humidity detected by the humidity sensor 2 is smaller than a humidity threshold value, the controller 3 controls the electric window I4 to be in an open state;
if the formaldehyde sensor 1 detects that the concentration of the indoor formaldehyde is smaller than a first threshold value and the outdoor humidity detected by the humidity sensor 2 is larger than a humidity threshold value, the controller 3 controls the electric window I4 to be in a closed state;
if the formaldehyde sensor 1 detects that the indoor formaldehyde concentration is greater than or equal to a first threshold value and is smaller than a second threshold value, and the outdoor humidity detected by the humidity sensor 2 is smaller than a humidity threshold value, the controller 3 controls the electric window I4 to be in an open state;
if the formaldehyde sensor 1 detects that the indoor formaldehyde concentration is greater than or equal to a first threshold value and is smaller than a second threshold value, and the outdoor humidity detected by the humidity sensor 2 is greater than a humidity threshold value, the controller 3 controls the electric window I4 to be in a closed state;
if the formaldehyde sensor 1 detects that the indoor formaldehyde concentration is greater than the second threshold value, the controller 3 controls the first electric window to be in an open state, the second threshold value is greater than the first threshold value, the formaldehyde concentration corresponding to the second threshold value is large, harm to a human body is large, the formaldehyde concentration corresponding to the first threshold value is small, and influence on the human body is small.
