Measuring air quality is a crucial step in raising awareness among the public about the need to ensure the health of future generations. Even after receiving a good night's sleep, we frequently feel incredibly weak when getting out of bed. This occasionally occurs as a result of the nighttime enclosed room's poor air quality. This inexpensive air quality monitor uses a MQ135 air quality sensor to keep track of the air quality in a given space. Using a DHT11 sensor, it also measures the humidity and temperature of the room and displays the results on an OLED screen. This initiative is really helpful.
