IoT Air-Care

Vulnerable populations such as juveniles, the geriatrics, gestating females and individuals managing antecedent health concerns like COVID19 are particularly susceptible to the harmful ramifications of air pollution. According to the World Health Organization, each year, 3.2 million people die prematurely from illnesses attributable to the household air pollution caused by the incomplete combustion of solid fuels and kerosene. The proposed system aims to analyze the quality of indoor air using Raspberry Pi Pico W interfaced with sensors and implements real-time monitoring through Internet of Things (IoT). It employs MQ-135 sensor and DHT11 sensor to observe the smoke levels, temperature and humidity in the atmosphere. The accrued quantifiers are utilized to analyze the Air Quality Index (AQI). If the cleanliness standard exceeds safe thresholds (above 400ppm), an alert will be activated, to signal that dangerous air quality levels are present nearby. The information thus collected is monitored continuously through ThingSpeak and MQTT server.
