FIXING PROBLEMS OF AIR POLLUTION SYSTEM
ABSTARCT
ABOUT
ABSTRACT
Internet of Things (IoT) may be a worldwide system of “smart devices” which will sense and connect with their surroundings and interact with users and other systems. Global air pollution is one of the major concerns of our era. The level of pollution has increased with times by lot of things like the increase in population, increased vehicle use, industrialization and urbanization which ends up in harmful effects on human wellbeing by directly affecting health of population exposed to it. Air quality goes down when enough amount of harmful gases present in the air like carbon dioxide, smoke, alcohol, benzene, NH3, and NO2. In order to analyses we are developing an IOT Based pollution Monitoring System which we'll monitor the Air Quality over an internet server. Existing monitoring systems have inferior precision, low sensitivity, and need laboratory analysis. Therefore, improved monitoring systems are needed. To overcome the issues of existing systems, we propose a three-phase pollution monitoring system. In this IOT project, you can monitor the pollution level from anywhere using your computer or mobile device. It measures their amount exactly and finds out harmful gases.

DATA TRANSFER AFTER RECONNECTION
WIFI RECONNECTION
DATA STORAGE
WHILE WIFI IS OFF
FLOW OF SOLUTION
- WIFI RECONNECTION
- DATA STORAGE WHEN THERE IS NO INTERNET.
- DATA TRANSFER AFTER RECONNECTION
> FLOW OF SOLUTION
Wifi reconnection
> WIFI RECONNECTION
- In the project the drawback was the frequent wifi disconnection.
- We have solved the problem by using
WiFi.setSleepMode(WIFI_NONE_SLEEP)
which reconnects to wifi automatically.
DATA STORAGE AND TRANSFER
Storage of data when wifi is OFF
Transfering data after reconnection
>RECOVERING DATA
The data stored in EEPROM is transferred to cloud.It can be displayed on the BLYNK APP which is a platform to cloud storage.
The ESP8266 microcontroller has a Flash memory area to simulate the EEPROM of the Arduino. This is a special memory location in the microcontroller where data remains in memory even after the board is turned off.
The overall flash memory size is usually 4MB. The EEPROM of the ESP8266 has a size of 4kB.

- Running out of EEPROM memory storage.Which can be solved by using a SD card.
- Change of WIFI credentials
FUTURE SCOPE
> FUTURE SCOPE
- An alarm can be added and can be made to ring when the concentration levels reach a higher fixed value.
- A message can be sent when a large change in concentrations are observed about some time period.
