Story

The air pollution has been increased all over the world, if this continues we cannot live a healthy life in the city. Most of the Metropolitan cities have installed pollution-monitoring devices in industrial areas, but these devices are not much effective, since the factories located either inside or outside the city. The people in the city are living without knowing their quality of breathing air. a city with on average holds more than 25, 000 small, medium, large-scale industries which may produce up to 6050 units-mil tons of Carbon dioxide (CO2). Hence there is no device for notifying government/city municipality/people about the quality of the air in their residential area.

the main idea is to notify the people about the amount of pollution present in their city by installing various devices all over the city and their respective data can be accessed via ubidots dashboard

the device uses a soc- particle photon that gathers the data from the mq135 gas sensor which measures the amount of co2 present in the atmosphere and the data is sent to the ubidots cloud, from which we can access the data via dashboard
