A sensor is operated through an aduinounobod, and a motor is driven to open and close the window.
In order to create an aduino code, the criteria for the PM2.5 sensing sensor were taken separately when the window was closed and when they were open.
First, if the window is closed, if the concentration of fine dust is less than 100 (if the air is good), open the window and if the concentration of fine dust exceeds 100 (if the air is bad), make sure that the window does not change at all the same time.
If the window is open, if the concentration of particulate matter is less than 100, the window will remain unchanged, and if the concentration of particulate matter exceeds 100, the window will be closed.
If the concentration of carbon monoxide gas sensor is 400 ppm lower, there will be no change, and if the concentration is higher than 400 ppm, the door will be opened.
Rainwater sensors should be set to 340 when one or two drops are detected and 300 when three drops are detected. If more than eight drops of rainwater are detected, the sensor value should be set to 60 and the other sensor values should be set up.
