Abstract

Air quality, temperature, and air humidity are pivotal factors that impact human well-being. These factors hold particular significance for children, especially infants, in comparison to adults. The quality of the air is gauged through the air pollution index, where a normal range falls between 0 and 100 IPUs. Air pollution indexes exceeding 100 are considered poor and are likely to impede respiratory health. Elevated temperature values surpassing room temperature can lead to increased energy consumption when utilizing fans or air conditioners to regulate indoor temperatures. Unnecessary energy wastage can occur if fans or air conditioners continue running even when the ambient temperature drops below room temperature. Excessive indoor air humidity promotes mildew growth, resulting in respiratory issues and potential harm to occupants within the household. An arrangement has been devised employing WEMOS D1 Wifi, alongside MQ135 and DHT11 sensors, with the aim of gauging and overseeing indoor air quality, temperature, and humidity through online connectivity. The obtained readings for air quality, temperature, and humidity levels will be viewable on the Blynk mobile application. This mechanism is geared towards notifying the occupants if the current air quality becomes unsuitable for breathing, subsequently activating the ventilation system automatically. The primary purpose of this system is to vigilantly monitor and enhance the well-being and living conditions of residents, particularly children, and infants. This is achieved by mitigating the risks of respiratory ailments, and fungal contamination, and ensuring more efficient electricity consumption.Keywords: Air quality, air quality index, WEMOS D1, Blynk.
