Abstract

DESIGN AND IMPLEMENTATION OF SMART AIR QUALITY DETECTION SYSTEM ABSTRACT Pure air is the need of every human as air pollutants affect both human health and the surrounding environment. Air pollution causes both long term and short term health effects. Several researchers are attracted towards detection of air quality based on technology. This invention focuses on development of a smart system for detecting the quality of the air. This work involves design of an intelligent sensor able to detect the air quality automatically. This sensor system is able to monitor environmental parameters such as concentration of carbon dioxide (C02), temperature, smoke, humidity and dust particles in the air. These parameters are key terms indicating the quality of the air. The sensed data is communicated wirelessly via Wi-Fi network utilizing the control system based on the modern protocol of MQTT. The user is able to access the sensed data from remote locations through wireless network. The technology of Internet of Things is involved for visualizing the measured data in real time from any location. This kind of real time air quality detecting system is high demanded in home automationapplications. Dustsensor SCD30 Fan 0C, 02 It Figure 1.

TITLE OF THE INVENTION DESIGN AND IMPLEMENTATION OF SMART AIR QUALITY DETECTION SYSTEM APPLICANT
The following specification particularly describes the invention and the manner in which it is to be performed
DESIGN AND IMPLEMENTATION OF SMART AIR QUALITY DETECTION SYSTEM Description of the system
" In this invention, a smart air quality detection system is proposed based on
the technology of Internet of Things, allowing the user to access air quality
and related parameters from remote location through Application.
• Safe level of air quality is between the ranges 350 PPM to 1000 PPM. When
it exceeds this limit it causes side effects such as sleepiness, stuffy
& stagnant air and headaches.
• If the air quality exceeds 2000 PPM then different diseases are caused with
increased heart rate.
• The air quality detection system utilizes ESP8266 microcontroller along
with analog sensor GP2Y101AU0F and digital sensor SCD30.
• Prototype system operates at power supply of 5V able to access MQTT.
• The digital sensor SCD30 is able to sense amount of carbon dioxide in the
air, humidity and temperature of the air. This digital sensor is able to
communicate data through 12C bus.
• This digital sensor measure the parameters every two seconds which is
enough for analysis purpose and updates it to cloud storage which can be
accessed by the detection system and the user from any remote location.
" The concentration of dust particle in air is sensed by the optical analog
sensor included in the detection system which can distinguish dust from
smoke. This sensor involves an infrared diode along with an optical detector.
• Infrared diode and optical detector are enclosed in a well defined angle.
• The lens system of the optical detector focuses on the small particles such as
dust and smoke which measures particles larger than that of carbon dioxide
molecule. Wired connection is provided between the controller and the
analog and digital sensor system.
• The sensor chamber is provided with a low speed fan for ensuring
continuous flow of air in order to measure the environmental parameters
with less error especially while measuring concentration of carbon dioxide.
• Any changes in pressure results in huge error in the C02 measurement.
• Measurement process can be controlled by a transistor switch physically or
through remote locate through MQTT (Message Queuing Telemetry
Transport) which controls the device from remote location through IOT
(Internet of Things)
• On one end of the proposed air quality detection system, the fan pulls the air
inside the system, followed by SCD30 sensor which senses the carbon dioxide present in the air and then the air is allowed through dust sensor involving optical detector and infrared diode.
• Temperature, humidity, concentration of carbon dioxide, amount of dust and
smoke is displayed to the user.
• Web application is developed for facilitating the display of these parameters
such that user is able to access the sensed data from remote locations.
• The controller of this system namely 32 bits RISC microcontroller
ESP8266 operates at 80MHz integrates WiFi module for ensuring
communication with the control system.
• The controller is programmed such that the sensed data is compared with
threshold data already stored in the program.
• If the sensed parameters are more than the threshold values then the result is
displayed as polluted air. Level of pollution is indicated as less polluted air,
moderately polluted air and highly polluted air.
• Air quality is represented using PPM, harmful gases such as NOx, NH3 and
benzene are detected using MQ135 sensor and detection of LPG gas is done
through MQ6 sensor measuring their amount accurately.
• The proposed invention facilitates monitoring the air quality from anywhere
either using mobile or using computer.
• The pollutant level when crosses threshold level, then alert SMS is sent to
the user with the recommended measures to be taken.
• If the air quality is less than 1000 PPM then webpage displays "Fresh Air".
• If the air quality is beyond 1000 PPM then webpage displays poor air,
provide ventilation and buzzer in the system beeps.
• If the air quality is beyond 2000 PPM then web page displays Danger! Move
to fresh Air, along with an alert message to the user.
• Live data of all parameters indicating air quality is displayed on the web
page too.
• The invention is herein described, with the accompanying block diagrams.
